It's 15634278, I think. You can find it on the right side of your intake manifold.

Thanks did that and now i guess its down to a fuel problem not getting any it seems.

not getting any it seems.

It happens to the best of us.

check your fuel pump relay. Just switch it with the rear window defog relay. If that dosnt work, most likely the fuel pump. Either check fuel pressure, or if its original, change the pump, strainer, and fuel pump filter.

Hahaha! :thumbsup: It sure does...

Have you checked the rubber fuel lines? Mine rotted and fell off, so I got no fuel... but it did go all over the ground. ;)
