Sweet that would be awesome if we can (borrow) the parts lol. I was told check the ICM the advanced auto parts in goodlettsville has a tester to see if the ICM is good or not... I just pulled the fuel rail off and everything looks new. My friend from advanced auto said to put bottles under every injector and see if any of them leak and if not then crank the motor and see if all the injectors spray the same amount of gas and they all do and they spray good...

I think I said this once before,so have patience please. If you have fuel,have spark,compression,good compression above 100lbs and the correct timing,and injectors are opening,it has to fire,it has no choice,one of those is not correct.

I haven't checked the timing yet I didn't get off work till late tonight an dI couldn't get to an auto parts store. But I get off at 7 tomorrw and i'm gonna try the compression. I don't know if the timing is off or not. I'll check the compression tomorrow if nothing after the timing and I'm gonna try a 4 prong relay instead of the 5 prong relay if it still doesn't work i'll get a shop to check the timing. I can do some mechanics but nothing to messy the apartments we live in won't let any fluids get on the ground...

The end of the distributor looking like this couldn't have possibly had an effect on the firing.
