I have an 89 Chevy caprice with 5.7 throttle body, I have
changed fuel pump, module, fuel relay, can't get fire to my
throttle body or fuel pump. Any suggestions
TM, he has no power to the fuel pump, or to the TPS by the sounds of it. I know your good on this...
The module you changed, was it the ECU, and did you have it flashed to the vehicles vin number? This controls fuel injector pulse and the power for the fuel pump.
