Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.

SOURCE: The 4wd is not working on my 2003 gmc yukon,

Does the truck have a push button selector on the dash? If so, you need to replace the drive motor on the transfur case.

SOURCE: how do you reset the check engine light on a 2003

the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

How do i reset fuel pump switch on 2004 yukon


There is no reset switch. Is there more than one issue? Engine cranking, you have spark at the plugs, gasoline engine. You have fuel injector pulse? Any applicable trouble codes?
If more than one issue, have to check rpm signal.
If only fuel issue, check voltage and ground for the fuel pump motor, 5.3l engine, gray wire is voltage, black is ground.

What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem .

Fuel filter


It is located underneath the car on driver side, nearly under the driver seat. Follow the fuel pipe coming from the fuel tank.
