Fuse? ESPS not hooked up, wrong hookup of wiring..low battery, flooded....

Need more data

zaksblaklabel

it will crank but just wont catch. i retraced my steps for the wires and all the connections are good. i think it may be flooded as it has done that before. i'm a newb to working on this car so idk how else to describe. sorry for the vague post. i did smell gas last time i just tried to start it so going to try to fix as if it was flooded.

smelling gas is an indication that it may be flooded. Recheck all of your wire connections first. Your car (even if it wasn't the initial problem) is definitely flooded now. So, after checking your wiring, go through the deflood process. If that does not work, then put back on your OEM coils, wires, and plugs and see if you can get it started to help narrow down the issue.

Correct, follow the usual deflooding procedures...Holding the gas pedal down while trying to start her up, teak the plugs out and let em dry/clean em, etc... and give it a shot. I'm glad they added that to the late year second gen RX7's....I am teh person who always had to have a kill switch under the dash

did the deflood, took 2 times of pulling the fuel pump fuse but car started. thanks guys, now i cant wait to go for a drive and see how much the small tune up helped

k, just got back from a quick drive, car ran fine for a moment, then started to act like it wanted to die a little bit and also noticed a noise under 3/4 throttle. got it back home and popped the hood and the car just died on its own. started again and it seems to be idling a little rough, almost like its cammed.

New technology.....


Try resetting your ECU

zaksblaklabel

been letting it run and it seems to have idled back to normal. for some reason the fan is staying on though. idk if that has something to do with it maybe? gave it a little gas in the driveway and it didnt hesitate

zaksblaklabel

just disconnected the battery so we'll let it sit for a little while and see if that does anything.

there arent any check engine lights like there were before i changed those things today.

i did notice on the oil change that i did also that the oil was 5-30 instead of 5-20 but idk if that would make it stall out.

After re-connecting the battery the ECU will have reset and will need to re-learn trims...

It will take a few drive cycles to settle down, and then it will be OK

If you connected the wires wrong it would be easy to tell

zaksblaklabel

not to sound like a moron, but what would happen if the wires were run wrong? i do work on my srt-4 all the time. this is the first kinda maintennance thing i have done to the gf's rx8. the thing is bone stock except for a rotary radio **** lol.

i have never reconnect wires incorrectly on my car or any friends car that i have helped on so i am assuming that the car just wouldnt turn over?

The 'wrong' oil will make zero difference to the way the engine runs.

Make sure you DON'T connect the leads wrong - he means it would be easy to tell by the smoke coming from your wiring.......

k, reconnected the battery, car started and died instantly. started the car again and again died instantly. started a 3rd time and gave some gas to get it to keep running. now the dsc light is flashing and the stability control signal (swerving car) stays on.

zaksblaklabel

let the car run for 15 minutes and those lights stayed on. disconnected the battery again and going to let it sit a little longer this time.

Mate every time you are disconnecting the Battery you are resetting ECU as Dan above says, it will take a few drive cycles (drive till HOT, stop, stone cold, drive, stop, stone cold, drive stop,etc) to re-learn Fuel Trims and car should settle down.

So stop disconnecting the battery.

DCS lights are on etc because you Disconnected battery.
You have to do the Power steering reset job, that is start car, turn wheel all the way to left and then right, or the other way around..can't recall as I have never had to do it.

USE THE SEARCH BUTTON>>>

zaksblaklabel

tried the search button but i guess i didnt put the right term in. thanks for the info

I had my ECL come on a few months ago. I connected my AccessPort to it and found it was part of the ignition was bad. I replaced the coils but the car wouldn't start. After a while of trying to start it I gave up and checked everything only to find that one of the plugs was the problem. Replaced all plugs and then I had the same issues you're talking about.

After all the times strying to start it when the bad plug was there it had completely flooded the engine. It did the start/die thing a few times. Eventually I got it started and left it running for 15 minutes to make sure it didn't die. Then I went out on the road and gave it f****n socks on the motorway. This got rid of the excess fuel and did a bit of spring cleaning when it came to the carbon build up.

The start/die thing is normal. It will happen a few times but when you get it going, leave it sit there for about 15 mins then drive the s*** out of it. Mine was perfect again after I did this If you get it started and it dies before 15 mins just restart it and keep doing this until it settles and runs for 15 mins without issue.

Hope this solves your problem

zaksblaklabel

thank you for the response. i got the car running but i need to take another look at the plugs. it seems to break up in higher rpms so i am going to check the plug gap and maybe shorten that a bit and try it again. the deflood definitely solved the problem.

EinHeisserSchrei

Good stuff. For me, it turned out that one of the leading plugs had cracks and burns around the white part hence it wasn't sparking at all which led to serious flooding Glad to help!

So your porcelain was cracked...good to hear it is fixed!!!

EinHeisserSchrei

Ah that's what it is! Porcelain! Good to know it's not plastic as some people told me haha

Yeah it cracked due to a very lean mix which has been resolved with some AP tweaking when I installed a new set of plugs.
