I am posting this again, so I can try and get the piece of junk running. I swear this has been the worst car I have ever owned.
I have a 88 GTA and it will not start. I will crank it over, and it will fire, and run for a second. Then it will die, and I can not get it going again. If I let it sit about a hour I will go through the same prosses again. It used to do this once a week, and I would let it sit for about 15 min, then it would fire and go. Now it won't start period.
It has a new fuel pump, a new motor that is a 350 L98, and it has all new distributor, wires, and plugs, I know it has spark, and I am not sure if it is getting fuel. I need some suggestions for what the problem might be. If any one can help please do so. THANKS.

 

Hook up a fuel pressure gauge and verify it is getting fuel.

 

I'd look into some VATS related issues cutting the signal to your injectors, thus shutting off fuel to the cylinders. Fuel pressure guage wouldn't reveal that problem.

Do some searches for Trickster.

This may help.

pull a easy to access plug. Is it drenched in fuel? What does the spark plug read?

Verify fuel pressure. See what color the spark is from a spark plug. Check out the spray pattern on your injectors.

Simple things should get you started well.

GOOD LUCK!
