So my car had the cel light flashing and the code was a misfire, I recently had new spark plugs and wires so I bought new coils. The car was still running and working just fine before the install it only had that misfire cel, after I install the new coils, put everything back together the car wont start, the coils are not getting any power. I checked all the fuses, double check that the wires were connected right. I just can't find what I did wrong with such an easy install. Thanks in advance for any help you guys can give.

how long ago did you change the plugs/ wires?
it's usually recommended to change the plugs/ coils at the same time to ensure even wear.

Check your cat for damage, also

How do you know the coils aren't getting any power?

Did you disconnevt that battery when you did this change over? If so..............did you reconnect it?

Does the starter motor try to spin at all?


And...........are these OEM coils?


Go check all your wiring to the coils and makes sure all connectors are good to go and you didn't mix then up there.
Also, I think there is a ground that you better check as well.


If you look at the connectors leading to the coils, I think you will find the following colors to help you make sure they are in the right order, but I don't really suspect this is your problem at the moment.

Front leading............green wire
Front trailing.............white
Rear Leading............yellow/green
Rear Trailing.............blue/orange

Depending on the year of your car, the colored wires could either be in the middle of each connector or possibly on the outside.
04's should be middle and 05(and above as far as I know) the colored are on the outside.




When you say won't start, need you to be more specific!

OK did my checks and everything seems to be connected just fine, when I try to start the car you can tell that is all the starter and no fire inside, where is that ground you mentioned, researching in the forum I red about it but can't find exactly how to check for it. Thanks. Just got new wheels too and I can't wait to take it to the garage to have them install. Oh also something that I did not mention before, before installing the coils I also replace the power steering harness which it was pretty bad. But like I said everything was working perfect before the dam install. Again thank you guys for any help.

OK Try this the ESS reset. Turn the car to on but do not start. Press the brake pedal 20 times in a 8 second or period. If done right the oil pressure guage will sweep.

Did the ESS reset, took it out cleaned it (btw it was really really nasty) and put everything back together and it still the same way.

You guys think it may be the ECU? Will a AT ECU fit a 6MT? Thanks.

Manic Mechanic

Check the eccentric shaft position sensor and its connectors. If there's no sparks it might not see that the engine is turning.

VOODOO8

Wow, quite a leap from a presumed no spark condition to thinking the ECU needs to be replaced. What got you headed in this direction?

Before going down that path you probably should be sure you have exhausted other possibilities. Back to spark, have you physically checked (like pull a plug and physcially confirm it is not sparking when the engine is cranked - there are plenty of threads on this forum on how to do this if your not familiar with it)?

If you are actually getting spark, then there is the possibility that things got crossed up when doing coils, etc so your not firing the right plug at the right time.

Last, you could have inadvertently flooded it while doing other stuff. Might want to try a deflood procedure.

Bottom line, I'm thinking there are lots of other things to be looking at before jumping to the ECU - especially crossing ECU's between AT and MT vehicles.

Mazurfer

I gotta agree with Voodoo. I still wanna know how you verified no spark, but I can't get you to answer the question or I missed it.
So the car was running fine before the coil swap right?
Therefore, the ESS reset shouldn't have done anything at all. Now you've cleaned it(the ESS) and put it back in, so you added yet another variable.
Yeah, it possible you've flooded it now, so you may have to try that, but first please, please, please, confirm there is spark or no spark, just as Voodoo says.

Please read what he wrote once more:

Ok so, the coils are ok they have power, all four, I disconnect the cable but let it close enough to see the spark and all four are working, the thing is that before the install my car use to start right away, so when I try to start it after I only try for like 2 seconds each time, did this many times. So now I tried it again but this time I let it for like 5 seconds and the car sounds like is flooded and you can smell gas.

Mazurfer

Yep, go for the deflood proceedure then I believe.


Manunal or Auto.............I don't recall. If manual then pull start it. Get it up to about 18mph in 2nd gear and let the clutch out. When it fires, go to nuetral and don't let it stall. Then you need toi take for a spirited run after warm-up.

Auto..........gonna have to pull plugs, get them really dry, probably pull fuel relay, crank in short bursts of 5-7 seconds without plugs in until you see no puffs of smoke from plugs holes and no weepage of fuel/oil out the holes. Then install the plugs and fuel relay and give it a go.
Sometimes this process takes more than once and there are several methods. Might wanna search and see which one you wanna try.

Sorry guys that I did not confirmed before, I think is definitely flooded, I just suck at this, I would have taken it to a shop or ask Paul for help but I moved and can't get a hold of him. But again the coils are working just fine all four do have a spark.

Mazurfer

It okay, but we do ask questions for a specific reason and sometimes we even ask in a specific order. Now, seems like you need to deflood, so see my post above or do some searches. Good luck!
Let us know when it's running.

Pull those plugs and see how bad/wet they look!

OK finally, it was definitely flooded. I just unplug my fuel fuse and relay and crank it a couple of times to burn that extra fuel, the car actually try to start in the process, put the fuse and relay back and crank it again, took me like 4 to 5 times but it start, huge smoke cloud, took it for a ride and I saw my cel light is not flashing anymore and my power steering is back too. "OH HAPPY DAY!!". Thank you guys for helping me with this, sorry if I wasted some of your time by not testing them coils before. Anyway the car is working just fine again. BTW I'm going to be selling the 18" konig wheels with no tires for like 400+ shipping if any of you guys are interested I'll give you first dibs on it. The wheels are the ones in car right now and I have some pictures in my profile. Again thanks a lot for the help.

Mazurfer

I'm glad it finally cranked and got running, that's the main thing.
I don't think anybody was really frustrated, we were trying to help.
Now.........I imagine it's re-learning the fuel trims, so it might stall for a drive cycle or to when coming to a stop, but hopefully you won't even have that.

Now, you probably need to attack the power steering connectors when time as this is a widely known issue.
Searches will lead you to what to do there, but maybe you'll get lucky and it will stay as is......who knows?
