Where is the fuel pump relay switch on a 2002 Chevy Yukon?
There is no fuel pump relay switch

I would have to check the fuel pump with a scope to look at the pattern and check the amps it is drawing . the grounds need to be checked and the pcm checked and reflashed. on the fuel system that would affect the fuel pump and relay to where it would burn it out is grounds , pcm , fuel pump , fuel pump relay. so you should convince them to replace the fuel pump and fuel pump relay under warranty and replace the pcm . and get a diagram and check all grounds. If the pcm is damaged and the current has been affected and instead of say a 5 volt or 2 volt signal it now has a 13.5 volt signal or if a ground is out then the temp of the relay will keep rising non energized a relay is about 99 energized it is around 140 you can check to see how hot that relay is getting. and if i remember correctly you want the pcm drivers checked.

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: do you have to drop your tank to change fuel pump
Yes, you will need to remove the fuel tank. Replacing the fuel pump is a pain in the *** if you've never done it before.
