I said it COULD be that. I'd look.

No, you don't cut open any wiring, just look at it.

If you replaced the CKP, then it's not the sensor, it's gotta be the wiring or the ECU.

You could easily find out by testing the wiring following the instructions on HMAservice.com

Yes, your ECU could be bad.

Thanks, buddy!

I was just wondering about the cutting open the wiring because like 90% of it is in a taped-up bundle.

I keep you posted though!

Opening up the loom is fine to get at the wiring.

Ya just be careful not to slice anything while cutting it open or whatever.

I cannot for the life of me find any wiring schematics on HMAservice. I don't really see anything that'l help me there. Am I doing something wrong? I searched using "all content" and nothing seems specific to me issues.


Also, if I determine that my ECU is bad, how do I go about replacing it or fixing it?

You would just swap it out. Its not hard at all. If you knew anyone close to you then you could actually just swap quick and see if it worked.

Alright! Now I'm in the house and it's dark out... Can you tell me where the ECU is bolted? I've only been able to get to work on the car a few times and haven't tried to locate it, thanks. I'd love to be able to just run out tomorrow and locate it immediately. I don't mean to come off as lazy or stupid (even though I am both of those).

lol Its alright man. Its above where the fuses are inside. Its a silver box with 100 wires coming out of it. Removal is 2 10mm bolts on each side. Its a little easier if you take the lower part of the dash off.

My car still wont start... New discovery though, hence the new thread.

While turning my car over, a few seconds, stop, wait, try again etc. I go feel the header tube from cylinder #1 (drivers-side) and it get's warm/hot while 2, 3 and 4 are ice cold.

What's the significance of this?

Does this help dignose a no-start issue or at least lead me down a different path which was examining the CKP wiring.

I'm not willing to give in and have it towed!

That means they are likely not firing correctly. And no need for all the different threads my man. You cna have all the info in one and it would actually help to diagnose it all in one place.

Anyway how is spark? I know tis there but is it strong? Something is not letting any combustion happen. Have you pulled the rail off to verify fuel coming out?
