Asked by Jul 24, 2016 at 12:39 AM about the 2002 GMC Yukon 4WD

Question type: Maintenance & Repair

Working on my 2002 gmc yukon fuel problem.
Found at my relay I have power on one prong of
the relay but when I crank it I have no power to my
load side feed. I've been messing with it for a week
and can't figure out why. Any suggestions?

This could be two things, the ECM or you have a bad wire going from relay,if relay is in and you cut key to on do you hear or feel relay click?

Yes the relay clicks. I just have power to one source on my relay with key on engine off. When I crank it over I have no power to my other source. I had wiring repaired at a shop for my fuel pump put 500 km on it now it's doing this. Same symptoms as before but I checked the wiring and it's all good. My fuel gage does not read anything and the truck won't run

I had the fuse box out and all wires look fine under it

When cranking I have no power to the pin. But power to one side of the relay when just the key is on. I'm not the best when it comes to electrical. I'm stumped. . Know the problem but just can't figure out why. Thanks for the help
