1987 Chevrolet Celebrity
The car starts as it should and idles normal. After letting the car warm up drive at about no more than 40 mph the problems start. When giving it gas it's like it wants to stop. If I try to start it the car it will turnover but almost instantly die back out. After letting the car cool for about 1 or 2 hours I can start it back up. Still having the same sluggishness. Almost like its out of gas. Put a new fuel pump on new filter new plugs. I put a new coils. New PCM. And a new Ignition Module new oxygen senser.

LOST PLEASE HELP

I posted how to get the codes and how to clear them see what codes you have but you set codes by running the car with connectors unplugged. Let me know what codes you find.

Yes depending on which connectors are unplugged it will set codes because the computer will see a problem with the circuit thats how the computer knows to set the code in the first place. So do we have spark when it wont start to all the plugs?Do we have the correct fuel pressure when it wont start?So when it doesnt start it cranks over normal speed etc no signs of battery or alternator not charging issues?

Yes have spark to all the plugs and I put a new fuel pump on new filter and new battery. Correct fuel pressure I dont know but with and new fuel pump and filter I would think so if not why. It will start now when it's not hot. But will die after about 1 min.
If I let it cool down till it is cold it will start fine and run good till it gets to op. Temp then it will die agian

We need to make sure you have the correct fuel pressure when it won't start and run even though you said it has a new fuel we still need to rule that out. Do you have a multimeter to do some testing?

Have you checked the fuel pressure when it has trouble running?Also it wouldnt be a bad idea when your car is running bad to perform a back pressure test?
