Non starting Classic.
 

We have a 95 Classic in at the moment that will not start. We got the car in running, but with a knocking bottom end. The customer supplied a replacement engine complete less manifolds etc, so we swopped the ancillaries but the car now will not start. We have checked fuel and for spark, although weak, and it just fires slightly and that's it.
What we have found, on removing the cambelt covers is that the replacement engine has the metal cam pulleys with small sensor teeth on the rear, but the old engine has the plastic pulleys with the larger, round sensor marks. What I am trying to find out is whether the different pulleys would be enough for it not to fire, as this is causing a lot of head scratching.
Sorry for the long post, but any ideas would be apprieciated.

Hi, i have a sti v1. My old sti engine had metal cam wheels. My new engine has the plastic 1ns. Mine ran fine for over ayear now. But now wont start.

But i don't think your cam wheels are your problem.
You done a fault code check? Crank sensor maybe? Cam wheel had it? Cam sensor? Endless :(

I know you have probs done this but you got the coil packs pluged into the right connector?

Also your cam wheels obviously tells your cam sensor that the wheel is rotating, if it does not detect this obviously either cuts your engine or wont start. The change wont cause the problem, either a duff wheel or cam sesnor would.

But obviously there is also the other things that could stop your engine starting. Crank sensor, timing, idle control valve + many more. LoL will get scoob manual out again.

Anyway good luck, tell me how it goes. can't start mine either :(

Cambelt aligned with exhaust stroke rather than compression stroke?

I have just swapped my engine due to bottom end going, MY93 to MY97.

I had problem starting, would turn over just wouldn't fire, after checking everything I found it to be the cam sensor plug not pushed in fully.

Not sure if thats much help, but was the only prob I had and sounds very similar to yours

I have spoken to a few guys on here, and have gathered some useful info on this. It never hurts to learn more, and I will look at a few more things on this one.

Hope you get it sorted mate

hmmm i could answer this but as i work at a dealership and he thinks we're all thick i think i'll let him struggle

Here we go again with more smartarsed comments. I did not say dealers were thick, and sorry if you read it that way. What I was trying to say was that most dealers, not just Subaru, will not give technical information to independants, that's all. You can get down from your high horse now.:mad:

thats a bit of a p!sh attitude TBH

I'm starting to feel genuinely sorry for poor KPCraig. The tone/content of his posts come across as nothing less than sincere, honest and integral - totally on the level. What the hell has he done to deserve these comments FFS/!... He asked a perfectly sensible question and in totally good faith.

I bet he's totally miffed at some of the attitude shown - on a Subaru-dedicated forum to boot! (I know I would, FWIW?)

All I know is this... If I took my car in to a specialist and they came across a problem that, at first, they didn't know what it was, then I'd be very happy/gratefull that they managed to use their nouse and sort it with the help of using other people's knowlede/experienece! :) Rather that, than the outfit having too much pride, and charging me for loads of labour trying different things, but all to no avail! :confused:

At the end of the day, engine maladies can be very fickle and extremely hard to diagnose; no matter how many years of experience/expertise anyone may have (if only it were that easy)... And breathe.

no wonder alot of people feel these cars are driven by ar$eh0les after some of the replies this poor bloke has had so far in this thread and the other one there not far from being wrong, so what he had a problem he couldent fix were not all einsteins are we, he gave up his saturday/night/sunday to find a answer to his problem and had nothing but sh!t off of some members for it, such a helpfull lot scooby owners are ehh :Whatever_

Craig were not all to$$ers honest :)

Amen to that.

maybe that bloke just summed up why people have that view of dealerships with immature comments like that. just to let you kno KPcraig there are a lot of decent helpful people on this forum but you always get the odd idiot that ruins it. hope you get the problem sorted in the near future

The car is now running!
Turns out, after speaking to the owner, he forgot to tell me that it had a broken fuel pump connector!:mad: , so hidden under junk and the boot carpet we found the connecter, repaired it and now it runs fine. It must have got dislodged somehow when we were working on it.
How we would have located it I don't know, as it was priming, which threw us, as it must have been slightly touching, but maybe moving when the engine was cranked.
So, nothing that we had done was wrong, just would have been helpful if we had all the information from the customer. All done now though.
