Well an enine needs 3 things as you know, with spark there and obviously air getting in that leaves fuel. I would say that fuel is not getting somewhere. Possibly could be blocked injectors, could still be a fault with the fuel pump.

My guess is some sort of fuel problem, somewhere to start anyway.

Thanks for the quick Reply:thumbsup:
I have 2 cars here one for parts and i change the hole injector set up and was still the same there was lots of fuel in the injectors so looks like the fuel is getting to the injectors but the injectors are not letting the fuel in or some thing :unsure:

PS:the car i have for parts the moter runs nice so it cant be blocked injectors

and allso any one know if i can just change computers from one car to ather to test to see if it is that??

you could try that just so long as the computers were from the same make and model and same trans type.

I'm not too sure mate, what you described sounds wierd. if fuel is getting there then it sounds like a computer thing. I think its past me mate.

Spark, Fuel and Compression
Amen brother. Although in this case I think we can rule out compression as a problem, to lose enough compression on enough cylinders to stop it from starting would be fairly catastrophic and most likely would have been noticed.

Fuel, ok so it has pressure at the fuel rail, and you've chucked in a set of spare injectors and it still aint happy, hmmm. Might be worth taking a few minutes to whip off the throttle body and make sure the bugger is clean, unlikely to stop it from starting but it can't hurt right? Once you've ensured that it's getting air and fuel then it's time to move on to spark.

You say it has spark, have you checked the plugs on all cylinders? What condition are the plugs/leads/dizzy cap in? If they're all cool then things could become interesting.

Like slundy said, if the cars are the same model and transmission type the computers will be interchangeable, and once again it can't hurt to try, but I'd be making sure all the basics were eliminated first.
