I have a '02 Chevy Silverado v8 with a fuel problem. I was driving it one day and the truck just died and would not start. So I towed it home. I believed it to be the fuel pump so I bought a new one and replaced it. After the change, the pump comes on but no fuel is getting to at least the fuel filter. I made sure that all the lines and wiring was correct. I have checked fuses, relays and a few other things. Truck turns over and will start if I put fuel through the breather. Any help would be grateful.

Wiring harness was updated
If the replacement of the fuel pump didn’t include the wiring harness
recheck connector and wiring harness heck relay and its wiring

I think I found out part or all of the problem. I blew compressed air through the fuel pressure check valve and got the truck to run for about 5 minutes. I will be trying to do this to all the lines and replacing the fuel filter and go from there. @BMRFIXIT the new pump came with the new harness and I did replace it. Thanks for the response.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
