How do you test fuel pump on 1999 Chevy Tahoe?

Answer:
Fuel pressure test. If you cannot hear it run for a few seconds when you turn the ignition on without starting the engine, then check the fuse and fuel pump relay. If it runs but you are not getting enough fuel, replace the fuel filter. If you still have the problem have a fuel pressure test run to see if the pump is weak.
