2003 GMC Yukon XL turns over, dies. No fuel.
Have a 2003 GMC Yukon XL. Yesterday
driving on the interstate I noticed all of a
sudden that as I pushed my foot down on
the gas pedal no gas was going into the
car. It started to die. I pulled over turned it
off and restarted the car it didn't want to
go and then all of a sudden came to life
and drove again for a little while and then
died again. Couldn't get it started again. It
would turn over it will chug and it will die
like it starved for fuel. I'm afraid it is the
fuel pump, but I want to make sure that it
isn't something easier or cheaper to fix
first. What should I be checking? Relays
seem fine. Did the old replace one relay for
another one in the car that is the same kind
and check trick. Switched fuel pump relay
with horn relay, horn still worked.
Yeah, sounds like a dead/ dying fuel pump... one quick test, disconnect the fuel filter, AIM the open line into a bucket and turn the key to on/ACC (do not turn the truck on)- the pump should pump fuel into the bucket- if that doesn't happen- for sure it's a dead pump. Either way you should consider changing the pump and the fuel filter. Good luck.
Are there any other electrical issues that could cause these symptoms? Just being thorough.
There are- but the best way to ensure that you DON'T have other issues is to start with what is wrong first; which sounds like the fuel pump and fuel filter (since your relays work and you don't have any blown fuses it is unlikely you have an electrical issue).
Is there an fuel pump access hatch in the Yukon? The tank is half full. That's a lot of fuel to syphon in order to drop the tank.
