We just put a brand new fuel pump, fuel relay, and fuel filter on our 1988 Chevy 1/2 ton 2wd 350 5.7 truck. The fuel pump will pump out gas but we can not get the truck to start. IF you use gas on the throttle injector it will run. We are out of ideas and any help is greatly appreciated.

Check the fuel pressure with a gauge to make sure the fuel pump is producing the correct fuel pressure and also check if the injectors are pulsing

Ok thanks for the response. Ok we have gas going to the injectors but the injectors are not letting any gas come out. Is this an electrical problem or? Thanks again

Check if the injectors have power if so -could be a problem with the injector/s driver circuit in the computer or its not getting an ignition references signal
