I have a 92 Camaro RS with the 3.1 V6 MPFI a couple of months ago it died on me while i was driving and would crank right back up and run for a few seconds and die i was led to think it was the fuel pump so i replaced it and nothing changed since then i have replaced the IAC, ECM, TPS, distributor, fuel pressure regulator, plugs and wires, oil pressure sensor, fuel pump relay, and the ignition switch but it continues to die after a few seconds or if i even touch the accelerator. Any ideas where i should look next?

 

does the car have a catalytic converter on it? drop the exhaust from the manifolds to see if the converter is plugged. what's the fuel pressure? try putting a fuel injector noid light on one injector and a spark tester on a cyl to try and see what's dropping out when it stalls. check fuel injector resistance, should be around 12-13 ohms. this engine has an external coil right? check the two connectors on the coil for loose terminals or maybe even a bad coil. check battery cable connections at battery and starter/grounds.
