CHEVY SHUTS OFF AFTER STARTING

1992 Chevrolet Blazer

Engine Performance problem
1992 Chevy Blazer 6 cyl Four Wheel Drive Automatic 174, 00 miles

I've owned the car for 5 years and in those years I've
replaced the fuel injectors and have replaced 4 fuel
pumps. Today similar starting problems as when I've
replaced fuel pumps, the only difference is by pressing
the gas pedal the car will start, however shakes as
if it's about to shut off. ANY HELP

Check the fuel pressure to see if the pump is creating enough pressure. Should be between 40 and 50 psi. Are you installing after market fuel pumps? You may want to try and oem pump.
