Not knowing what year your truck is I would say it's under the hood, drivers side inside the 'power distribution" box. Under the cover shows you which relay is what.
fuel pump relay location
Consult your owner's manual.
There is none.
Chevy did not use them on there trucks. Check fuel pump pressure, fuel pump FUSE and FUEL pump relay.
Chevy trucks DO NOT hve a switch like that. You either have a bad fuel pump FUSE,Relay are a pump.
Inside frame on drivers side
You will have to remove the fuel pump relay or the fuse for the fuel pump. You did not say what year it was, so I can't tell you where it is. SORRY.
the fuel pump relay is on the passenger side under the hood on the fire wall. behind the long black box which says fuel pump relay and some other stuff
Under the hood, drivers side, in the fuse/relay center.
Did you replace the fuel filter? Is the pump actually running? If not check the fuse and fuel pump relay.
it is located on the fire wall under the hood on passangers side. under a plastic cover that says fuel pump relay.
Chevy trucks DO NOT HAVE a safety switch / Inerita switch. You need to check the fuel pump relay and fuse first. You may just have a bad fuel pump.
