03 Fuel Problems
Have an 03 Chevy Av 1500.
Had a problem with the truck just dying but the fuel gauge still working (sender unit working)
Replaced just the pump and still nothing.
Replaced Fuel filter on rail, still nothing
new FPR on rail, Nothing.
What else could it be?
Check Valve in tank?

If you changed the fuel pump then you have a good check valve. Besides the check valve would cause longer cranking time, but it would start. Put a fuel pressure gauge on the fuel rail to see if you are getting good pressure.
