Doesn't want to hot start..?
 

I did a quick forum search and couldn't find my answer.
So, had my rx8 for 4 days now, she runs a dream, starts first pop, idles perfectly and has plenty of snot... BUT, my only issue is hot starts. From my house to the gas station, it takes about 30 mins, 90% is open rd driving. Once I finish filling, maybe 5 mins, it doesn't want to start. I hate to hold the key round and let it crank but it just doesn't fire up like it does from cold and its the only way I can get it to go. If I stop for like 45 mins, start up is fine.
Its a 2005 4spd auto and has 80,000kms, jap import.
I'm by no means technical and have no idea about codes and stuff, I've only ever had old school cars.
Just want to know possibly whats causing this, is it normal (water in the oil got me too) or is this the beginning of some bad news?

Could be bad news or it could be that it just needs some tlc .
Common issues :
bad battery
bad starter
bad coils
bad leads
bad plugs
or the big daddy ... bad compression

could be any one of those bad boys

4spd auto.
Check your compression and catalytic converter.
You should also try to understand what caused the problem to begin with. Bad ignition can kill the catalytic converter quick. Early pcm flashes had inadequate OMP rates etc.
It's a common problem, especially in early 4 speed auto models. A quick search will give you a lot to read.

Thanks, I was afraid you'd say that though :tear: sounds like money already :scared:
I just don't get how everything else seems great, when my skyline has issues, you know! the whole car runs like crap, but this is just one wee thing. Argh, frustration. I have alot to learn

If you live close to Hamilton I could diagnose it for you ...

Thanks Brettus but I'm down south, Oamaru. Pain in the arse cause I don't think we have a mazda dealership in town. I'd really only go to one of the reputable ones and they're in chch. Will have to read up, dig in, and see how much I can do on my own. Love rotas, but am begining to see why you don't see alot of them around. :suspect:

They require you to be dedicated that is for sure .

Have a look at this thread for starters :

Thanks Brettus, feeling like a bit of a dick not finding that on my own :uh:
Second thread, awesome. Bummed out about the compression tester though, have a piston one, thought I could get away with that for free at least.
Given me alot to start with, will have to figure out if anything has been done by mazda to my girl before she got imported.
Thanks again for the help :worship:

You can
just take out the check valve and when you do the test watch the needle pulses . Better yet - take a video of the gauge while someone turns over the engine . Then review the video frame by frame .

Don't forget to count the revs in a given amount of time to determine the rpms.

:icon_tup:

Oh wicked, thats good, very good.
Hey just cause I've got you on the thread, being a fellow kiwi ;) could you tell me what the availability of 6 spd gear boxes are in nz. I can't find any and im pretty keen to upscale. I thought the 4spd would be fine but this car just makes me want MORE :scared:
Oh and is there an easy way on the net to find out if my car has had any recall or warranty jobs, or do I just have to call mazda?
Thanks again

Not sure if anyone here has done that conversion (full motor and g/box has been done) but I think it would be a major. You would be better to sell the car and move to a 6 speed model.

I think you would like my turbo ;)



Think you would , yes .

But I just got it lol I love the car itself. Beaut colour, simple kit, wiked interior. Hmmm turbo... I do like that idea, but I think I like the whine of a supercharger.
Perhaps I should research some options, then by the time my finance is paid off, I should have a clearer idea in mind.
Spoke to some dick this morning who basically called me an idiot (which may or may not be true) for buying my car! I was put onto him as he rebuilds rotarys, and I wanted to ask him some questions regarding the compression test. He asked for some history on the car, which is in the 1st post, and no, I didn't get it checked out before I brought it :dunno: whatever. So he procceded to rant about it being a time bomb and blah blah blah, shoulda blah blah blah. And heres me just thinking WTF mate I just wanted some advice, not a goddam earfull.
So now I'm feeling like a scalded f*#king cat. Yes it was an impulse buy and yes I'm a relatively clueless female but I'm giving it a crack. I really didn't need that shit :mad:
Sorry, hadta blat

Oh boy - that is not what you want to hear about your pride and joy . Your description of events did give me a chuckle though .
Think of it this way - you have a unique car that is a blast to drive and looks fantastic. By owning one you set yourself apart from all the ho-hum toyota driving , jersey wearing boring farts out there.
But that comes at a price .

If compression is your issue all is not lost - do a decarb .

he was right, the point being the sooner you accept and learn from your mistakes whether you want to hear about them or not the better off you will be the next time around ... but you'll probably just listen to what you want to hear and go do a pointless decarb that won't change anything

I have seen a 0psi (on one rotor) engine resurrected to run perfectly doing one of those "pointless decarbs" .

using the same technique as this guy

Hey unless you can't read, you'll see that I went for advice for a problem I KNOW I HAVE, I'm not in any kind of denial, I just don't think it was neccesary for him to be an asshole. Either he has a problem with 'females' or like you, he thinks he knows everything.
If you don't have anything constructive to add to this post, then piss off. I'm here to LEARN and sort out my car, not to listen to shit from egotistic wankers! :mad:

Yeah, I'm just a tad defensive :cwm27: I've been told that many times that females shouldn't be allowed near cars that the minute someone pairs 'idiot' and 'female', it's on! I bought the car knowing that at some stage it'd blow an engine, I just hoped, not so soonish.

Oh thats wicked news.
The hot start was better when I took her out last night. Maybe it's just been due a good thrash? Going to check out my coils, plugs, leads etc on Monday so I've got my fingers crossed it's something simple. My warranty forms are on their way so I can see what I'm covered for incase it is compression. If my cover won't front up with 70% + then I'll give that decarb a crack I think.
Although it'd be primo to start off with a fresh engine, then I know it'll be looked after.

Don't listen to Team - he is a grumpy old man that rarely has anything good to say .

To add to the above , i'm sure my compression is not good and i had hot starting issues as well . Fitting the faster upgraded starter motor completely cured the issue for me . another Kiwi on here had exactly the same experience.
Fast starter speed and good ignition will mask weak compression .

Perhaps I should just replace the lot? I got my insurance forms today from autosure, (not sure if you know them or not) all looks pretty legit. They wont cover stuff like the plugs and coils, or clutches and brake pads which seems pretty fair I guess, but they'll pay for any major mechanical breakdown to the market value of the car, obviously that wasn't caused by neglect or faulty parts.
Feeling much better now :mdrmed:
Wheres the best place to get genuine mazda parts? .... cheaply :o:
Can't wait to get stuck in and have her running perfect.
Brettus, you have saved my sanity this week :worship: thanks

hey,,

you for got to ask her what she was wearing!!!! :)

and i am impressed that the faster starter did it. i am with a old 120k motor and still the old style starter gets it done..

i am blessed! :)

beers :beer:

Mine did too - for a long time . but shove 12psi of boost up it for 30000 miles and then see how you get on .

I'm a farmer, so basically overalls, gumboots and plenty of cowshit :wavey:

I'm gunna show my workmate these, she'll wet herself laughing!!! Brilliant

You're really trying to test my google abilities.

brb

:fruit:





srsly though. Glad things are looking up for you and the car, and good luck getting the hot start sorted out.

HAHAH she called Team an egotistic wanker! I found this hilarious

my kind of girl ;)

is she colered in wool?

wow,

farmer with no common sense, dont believe that! but i joke brettus and you answer in a forum! well you screwed you self!!!! :lol:

anyway,

you will get great answers here between the pics and comments. i would mention the regional forum section. the aussi section is very helpful.

there is also a rx8 aussi site. i am a member there but have not been paying attention for a long while.. lots, and lots of info.

brettus knows is stuff. i am pretty good at the stuff that tends to break on the rx8, but specialize in the odd and obscure..

pm is good.

sorry about where the thread went!

beers :beer:

I just went through hot starting issues myself on an 05 with 65k miles and 40 on the engine, previous owner got new motor at 25k. At first cold starting was fine, but if it was not sitting for a couple hours, hot starting was very labored or not happening at all. Took it to the dealer, they said plugs coils and wires. Bought them myself, sure enough 2 of the plugs were sparking through, but still starting issues.

Finally just bought a remanufactured starter, took the old one out, which happened the be the one they released the tech service bulletin for, and now shes good as new.

I bought non mazda parts and replaced all of those things for around $400 usd. If you bought all those parts in genuine mazda form, thats more like 7-800. the only things that were oem that I bought were the spark plugs, everything else was not. Many people on the forums seemed to have tried the non oem stuff and have had good luck.

Supercharging gets expensive(last time I looked its between 4-7000) and obviously you have a few other things to take care of first. Good luck with getting it going properly, and hopefully it does not take too much.

:lol: I'm unconcerned, I just found it really funny in the first place considering Brettus is older than my dad :cwm27:

Getting back on topic, car declining fast now, did some jobs in town yesterday and had to give up and park the girl up and walk. Very embarrassing episode at the gas station where she refused to start for 15 minutes. A number of concerned citizens came and asked me if I knew what I was doing :dunno:
Another small matter of having no idea what oil is in it as it doesn't say on the service sticker so will be doing an oil change today (sigh) the garage in town I was counting on to test my bits and bobs were too busy so that'll happen next week. So, the tramp is going to be popped in the garage and I'll have to get the skyline out again.
Have got the most awefull feeling it's something sinister as I've noticed a noise akin to noisy tappits. Don't know yet what it means for a rotary but am sure it's not good.
On the plus, still love her when she's going, still the best car I've ever owned and I'm certainly a few grand away from giving up just yet!

Thanks for the support, I'll be slowly working my way through the possibilities. It does have reasonably high ks and with no history (imported) it's hard to know what has or hasn't been done, but I'm fairly optimistic. I have a 12 month warranty that will cover the 'big stuff' so perhaps it wouldn't be so bad for it to be shagged, wouldn't mind a fresh egg beater :aroused:

I don't usually believe in those warranties - with the RX8 maybe it's worth it . Will be interested to hear how well you are looked after .

Yeah the Rx8 is the only rotary they cover, and after reading some fineprint, i'll get 5g max, but it'll still go a long way towards getting a new engine, rather than me paying the lot. Better than nothing eh?

Fuel Pump might be a place to look too...... :)

Rotagirl,

You might as well start with the least expensive, and easiest things to do.

Here, start with this thread:

https://www.rx8club.com/new-member-forum-197/congratulations-you-got-8-a-202548/

Once you're done with the simple things, like cleaning the MAF sensor, then go for a replacement starter, as that's going to help with the warm start issue.

Also, you might as well start premixing oil into the gas like a two stroke, as that might help a smidge with compression if the engine is borderline.

Coils, plugs, and wires will help if the ignition system is weak.
You can have these parts tested, or you can just call it maintenance since you probably don't know how old the components are in the car. If they are bad, they kill rotors quick.

You can have someone inspect the catalytic convertor if you want.
That's up to you.

After that, its time for a compression test.

BC.

Thanks, yeah I was pretty keen on replacing all I could as maintenance anyway. My question for you is though, I run her on the highest octane I can get- 98. Is this not nececarily enough? I know high octane fuel can hide alot of timing issues with piston engines but I'm just starting out with rotas and with alot of conflicting info, I'm still a bit cagey about trying things out, particularly with my shakey start groundings.
I know I can get this booster stuff for the gas, its not oil but that did wonders for an old car I had. Why would the extra oil help the compression? The oil I've topped up with is 10w-40 just to tide me over till the stuff I ordered arrived. I've only put in about 700ml so will that be enough to affect anything? Sorry if it's a dumb question but I'm trying to soak up all I can here.
I'm worried I'm going to do something incredibly daft :scared:

No need to run 98 octane in a stock 8 - just throwing money down the toilet . It will even run fine on 91 , but 95 is the recommended so stick with that.

The oil bladecutter is talking about is 2 stroke premix into the gas - it can help if compression is weak.

if thats a farm girl i need a ranch !!! :beer05: . hay rotagirl , my sister thinks like you... she can drive it break it , & fix most of what she broke . :D:. no, dont take any cow pattys from anyone !!!

Sorry it's been a while. Had the car at a rotary specialist at the dealers cost (found out a bit of dodgy background) and, not as bad as first thought. The mechanic didn't bother with a compression test, said she sounded sweet as. Just recommends replacing the O2 sensor and the coolant temp sensor. So, parts on their way, finally. Got a bit of info on my tappy noise too, port valves, brill. So going to get my no.1 local mech to price me up and sweet talk him into using the workshop and helping me :lol2:

If the temp sensor was not working at all it would affect starting - did he verify that ?
The 02 sensor -almost certainly not affecting it at all .

I hope it's not your money he is wasteing ?

All at dealers cost. The rotary guy said that the sensors were telling the car that it was cold and chucking in too much gas, thats why it didn't want to start. I can only go by what I'm told. Dealer has paid for the parts, not labour but again, I'm sure my mechanic in town can be pursuaded to help me out.
The guy at the rotary shop told me that the dealer himself had problems with the car when his gf was using it but didn't take it to a proper rotary garage to be diagnosed. Having this info, I'm pretty confident that I have some leverage should I have any more issues. The consumer guarantees act protects me too so stuff him. :evil_laug

If that is what is happening it is a pretty rare occurrence - not saying he is wrong at all but will be interested to hear if that fixes it .

So, was replacing O2 sensor, guess what...? Cat converter is shagged. :Wconfused And a rotary specialist couldn't have taken a quick peek??? Unscrewed the sensor and all this meshy shavings crap fell out, a wee wisp of smoke from one bit, brill. So I'm painfully reduced back to the skyline till I sort this out with the dealer.
When will I be able to drive my black beauty without a worry? :cwm27: Amazing how all other cars just feel so inferior

do what everyone else does and just have the innards taken out of the cat - will save you a lot of future heartache .

Get a compression test.

If your "rotory specialist" can't take the time to look at the condition of your convertor, and properly inspect your car, I wouldn't believe anything else he said about the car at all.

Go get a compression test.

BC.
