P reg - no spark at all

K30DPC · Post by **K30DPC** » Sat Sep 13, 2014 6:40 pm

So basicaly we have here 5 gen P reg prelude which doesn't wanna fire up. There is fuel smell so this isn't an issue. But there is no spark at all. First I replaced the coil, then ICM, and then full dizzy. And it still doesn't start.

Acording to circuit diagram from manual what signals ECU is sending to dizzy and how can I check are they correct? (in case there is something to do with immobiliser)

I have been told that the car spend some time on driveway. During this on one afternoon it was running fine, and few days later they couldn't start it. I'm not sure how much of truth is in it.

Any help much appreciated

check the earths?

checked and all good. I've cleaned all and put little of copper grease around bolts.

Can this be immobiliser fault?

Airbags ok? Couldn't be the "needs a reset after an accident" thingy? (Even if there has been none). Seems to come up quite often

Sorted. Faulty ignition coil from dizzy which I bought as a known fully working one. Ohm meter was showing 15.4kOhm which is in spec but it wasn't producing any sparks. Well... never trust the seller

Thanks guys

if you checked it and it was showing good how can you blame the seller these coils aren't the hardest things in the world to kill

I bought fully working dizzy, which come incomplete and not realy in working condition. At the end of the day I don't realy care. I don't even remember who sold it to me. I do get it as he could be not aware about faulty coil as like you said they are very sensitive. And I didn't mean to blame anybody. I said this as I was 100% sure it is working one, and I was ready to buy another ECU, I spent about two afternoons before engine start running, but it was so easy and simple fault.

The only one think I'm happy with is I'm only one more step away from saving another prelude - unluckily it's Vgen but it's alive. And I will become intergenerational luder

ahhh right if it was described as working but wasn't even complete then fair enough I wasn't having a go but rereading the post does look like I was having a go sorry bud

Don't have to be sorry.
