2001 Chevy Silverado fuel pump issues

Asked by Apr 01, 2017 at 03:17 PM about the 2001 Chevrolet Silverado 1500 Extended Cab SB

Question type: Maintenance & Repair

I replaced my fuel pump in my 2001 Chevy Silverado 4.3 liter v6. I
removed the bed and installed a new fuel pump I tried to start the
truck after the installation and it's still acting starved for fuel and I
don't hear the fuel pump coming on. So I went back to the auto parts
store and swapped the new pump for another new pump and same
thing. I changed the relay I don't have a way to test fuel pressure. My
question is would the ground wire from the fill neck of the gas tank
not being hooked up make the fuel pump not come on? The ground
wire is only connected to the filler neck and to the bed of the truck. I
didn't put the bed back on after the installation.

It started prior to me doing the fuel pump but it wasn't reliable. Sometimes it would leave me stranded. And when it wouldn't start I couldn't hear the fuel pump.

Just ground out that wire, just sounds like the fuel pump is not running because of no power.

Check any ground back there. just try and ground out that wire,

Not so much a wire but a strap

Just doesn't sound like the fuel pump is running. There should be a black wire for ground at the fuel pump, the strap must be bolted to the frame then to the filer neck, thats just for static discharge from when your filling the tank. You need a test light or volt meter to see if there is power to the fuel pump. If there is, it is a ground wire not making connection for the pump to run.

Just found out it was a bad ground wire leading to the fuel pump
