The fuel pump relay has no relay. Only a yellow 20 amp fuse for the pump. It may be marked under the plastic cover but not present. The control module under the truck box took the place of the fuel pump relay or fuel pump regulator. It is a 5"×5" flat box about 1/2 in. Thick bolted up under the box. Remove spare tire to get to it.

Remember: There is nothing in the fuse box marked [Fuel Pump] location. Because you have a ECM electronic control module. You only have a yellow 20 Amp fuse in the upper far right corner of the fuse box panel under the hood. Extra tip: replace your oil pressure switch. It way in the back of the motor. You need a 27mm deep well socket, 3/8 drive and a stubby flex ratchet, small hands help too.

Had any one tried fuel system cleaner to free up the check valve ? When it faces down hill it starts good but all the fuel go's back to the tank facing up hill.

i looked at schematics of 2011 silverado and found no visible fuel pump fuse but 5 fuses related to module power from ecm.and nobody is checking the grounds for that rear fuel pump module that is on frame at drivers feet.the ecm is using that rear fuel pump/brake control module to control fuel pump action plus other things.and i did not see any action from oil pressure except ecm will know if its ok.2007 up in yrs,and used module 2 yrs only..i said enough,figure the rest urself.ex gm service tech,

mine was ground wire under the driver side floorboard where the e brake cable come out of floor. the ground wire was loose. tightened it up and she started right up. cheaper than an ecm or fuel pump

My fuel pump had would not run this morning, crank but no start situation. After finding this post, I checked the FSCM Fuse # 21, and found it had corroded itself to death. Looks like an original to my 2010 1500 Sierra truck. I also have no fuel pump relay or fuel pump fuse, even though the diagram inside the fuse panel shows them. Thank you.
