Have you verified voltage at the fuse and fuel pump relay. There is one fuse in the underhood fuse box.
Let me know.
Regards,

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.

Why does my 2003 Yukon XL turn over but won't start?


Does fuel pump run ? Remove fuel cap. Have someone crank it for you,you should hear fuel pump running. If not bang on bottom of tank while cranking. If it starts fuel pump will need replacing , if not check for power to pump, if it has power,replace pump. If no power, check relay for operation

Denali low fuel indicator


Have a friend lay/sit/crouch by the back of your truck(Where the tank is), and turn the key on. they should hear a "whirring" sound.
If they do, the pump is fine(Check fuel filter). If they hear nothing, replace your fuel pump!

My windshield washer pump will not run on my 2003 GMC Yukon. I have replaced the pump, checked the fuses in the left inst. panel area (25 amp) and under the hood (15 amp).


you didnt mention if you checked the RELAY??? you should be able to swap it with another relay in the fuse box, the map will show you which one it is. The 25 amp powers the wiper motor, the 15amp the pump.

Yeah what's you saying is right, and GM is having a big problem with Fuel Pump on such model, I Already saw a 2 Year Cobalt with a Dead Fuel Pump.. ! Best thing is Keep your tank more than the Quarter, Buy a Dealer Fuel Pump not a Jobber one, be sure the strainer is clean in the tank and check if there's any dirt in your Fuel tank ! Check too if there's any Recall about that on your Vehicle !

2001 YUKON STARTS WILL STARTER FLUID BUT DIES AFTER 5-6 SECONDS..COULD IT BE THE FUEL PUMP I REPLACED THE FUEL PUMP 3 MONTHS AGO OR DID THE MECHANIC **** ME.


If you've replaced the fuel pump recently, I would check the fuel filer as well as the fuel pump relay. You can take the fuel filter off and blow into it in the same direction as the fuel flow and it shouldn't be restricted. The fuel pump relay is located in the fuse block underneath your hood close to the firewall. Before trying either of the above you may also make sure the fuel pump cutoff switch has not been activated. These are usually located on the firewall or in the rear of the vehicle behind a panel. It will look like a push button switch that you just push in to reset it. Let me know if any of this helps.
