Question about 2002 Chevrolet Suburban
I replaced my fuel pump thinking it went out but the fuel pump is not getting fire....
Have you checked the fuel pump relay yet ?
It should have power for three seconds when you turn the key switch on, then power after the engine starts.

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

SOURCE: Fuse location for 2004 suburban
The fuel pump works when you crank the motor and after the motor started, have someone start the car at the same time go to the back and listen for the pump, is inside the fuel tank, but You can her if works or not, bzzzzz! noise, The pump has a Relay inside the engine compartment left side in most GM cars, is a plastic square box plugged in to fuse panel among many others that look the same, but on owners manual is a page that shows fuses and Relays

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

The # 5 cylinder is miss firing. not getting fuel. Could the injector just be stopped or the crankshaft sensor in gone.
