92 CAMARO Z28 5.7 TPI CRANKS IDLES, GOES DEAD AFTER PRESSING GAS PEDEL. I HAVE REPLACED FUEL PUMP,ONE INJECTOR AND THE ECM.CAR STILL DIES,WONT START OR JUST IDLE

If you have an other car and there is an Auto Zone, lone out a fuel pressure gauge and see where your fuel pressure is. Auto Zone will have the step by step instruction for you to get the fuel pressure readings from the shredder valve. Can't recall what the fuel pressure should be when fuel is primed and when it's the engine is running. If your in the low area, you may not have enough fuel pressure to activate the injectors when it calls for. Thinking it's around 42 PSI to 45 PSI on the TPI engine. When the engine is running the fuel drops around 5 PSI and you may be at the bottom of the minimum amount of fuel pressure in the system to keep the engine running when called for more fuel. Then we can try the fuel filter change too if it has not been done yet. Keep me posted friend.  If you have an other car and there is an Auto Zone, lone out a fuel pressure gauge and see where your fuel pressure is.
