CHEVROLET LUMINA FUEL PUMP PROBLEM

1990 Chevrolet Lumina • 159,156 miles

It starts and runs, idles ok until it gets warm misses a little. When you give it gas in park it dies down and wants to stall. If you put it in drive and give it gas it stalls. Then starts right back up and does the same thing. Doesn't seem to be getting fuel. I have changed all 6 injectors, the fuel filter, idle air control, crank sensor. You can hear the fuel pump running when you turn the switch on. No vacuum leaks found. Please help.

Have you checked fuel pump pressure? It may not be producing enough pressure to run the vehicle. Let me know.
