Question about 2002 GMC Sierra

2002 GMC sierra dies

I've got a 2002 Sierra 8.1 SLT. The truck dies about three times a day. No code ,No check engine light. It has a new fuel pump and filter. So I know that's not the prob. I've narrowed it down a bit. If It dies I just open the air box and 90% of the time it starts back up. If that dosn't work I have to disconnect the pos cable and it will start back up. I have cleaned up the MAS sensor and put a new air filter in it but it dosn't make a differance. Any thoughts?

When your replaced the pump did you replace the fuel filter? You may have a fuel pump relay causing you some grief. I believe it is located in the engine compartment in the fuse center on the left inner fender. Check the relay and any related fuses. Check the electrical connection at the pump. They had problems with some of them and they would get kind of hot and distort and corrode. They have new updated ones that can be easily installed.

Check connections at/or replace oil pressure switch. Your oil pressure switch is also a safety feature that shuts off power to fuel pump in case of accident or rollover.

Fuel pump- 2002 GMC Sierra


The fuel sending unit only controls the gas guage not the fuel supply to the vehicle. The pump is twelve volts. If you are not getting twelve volts on the PUMP wires check the fuel pump relay and the key circuit to it. If you have to cycle the key three to four times rapidly to get the vehicle to start check the fuel pump pressure at the regulator for manufacturer specs. An injector stuck open will also cause same problems you are describing.

1997 gmc sierra shuts off while driving


Had same problem with a Yukon. Turned out to be a bad fuel pump (Won't show codes.) When cold ran fine, heated up, no pressure. Would start after sitting for about 1/2 hour. When engine dies on you check for fuel pressure under the hood.
