How do i check to see if my fuel pump is working properly on my Chevy Silverado Z71
When you turn the key can you hear the fuel pump prime? If not, you can also check the fuel pressure. You can also probe the fuel pump wiring to determine if you have power going to the pump and check all fuses. Get a wiring diagram and a multimeter to check. Most times it's the pump itself. Get a fuel filter too.
