whats wrong

[MATT2007]

I have a 95 Chevy c 1500 and with a 350 and TBI the problem is that when The truck warms up it stops getting fuel I have so far replaced both injectors the ecu the ignition module(at the shop) and the fuel filter and still dose the same thing the shop told me it was the ignition module and they replaced that then they sent it home and it died on the way home that was the 4th time it has been there and they still can not find anything wrong I am stumped and pissed off any help would be great

The pump could be on its way out.

Will it do it when parked? If so you need to check fuel pressure at the time of shutdown and also watch the injectors. If you have no pressure when it fails your fuel pump or the oil pressure sending unit is dying. If you have pressure when it fails then check the injectors for fuel while it is dying. If it sprays fuel as it dies then it is an ignition/electrical problem.

okay it stops getting fuel when warmed up, you've replaced the injectors and pcm.
it's possible that the oil switch is failing or it thinks the oil pressure is too low and causes the fuel to shut off.

or the pump could be bad, clogged fuel filter, bad map sensor, or coolant temp sensor...flowing enough fuel that you don't notice, and when it wrms up it could evaporate and the engine is'nt getting enough fuel, and seeing it's a gm they LOVE to get hot.

i say take off the lid and look at how the injectors spary from cold start all the way to operating temp, and see whats going on.
