Last night my 83 GSL ran out of gas during a warm-up idle. (I know a bonehead thing to let happen, but my gas gauge needle is missing, so I didn't know I was low)

I thought it was no big deal, but all of a sudden, my pump doesn't click on when I have my key turned to the on position.

Fuses are ok, I replaced the pump, and still no love. I'm thinking about trying to bypass the relay, but don't know where I should be digging into, and would be super grateful if anyone had some pictures or an explanation for me.

Thanks

 

Turns out my short starts all the way up at the top of the wiring harness. . .

:-( looks like I've got my work cut out for me.

 

Please explain. I might be in the same predicament and would like to know more information. I too am not getting the customary fuel pump hum at the ON position. It is dead silent.

Are you saying you found your short visually and it is in the engine bay in the wiring harness? If so, how did you track it down? Is this a common problem on these cars?

Thanks

 

We followed the wire from the fuel pump through the harness, (and the firewall) and then tested it as close to the battery as we could. And got nothing. :-(

So we ran a direct line from the battery to a switch, from the switch to the fuel pump. Had we been able to do that to begin with, I might not have had to tear as much of the car up to find that wire.

I just wish I had a camera that took decent pics. All I have is my phone's camera, and that is absolute *****.

Before you go pulling all kinds of wires, check your fuel pump on the battery (after you drain it. . .) I thought my pump had died, and got another one from pick n pull, but my old one was working just fine when we tested it. (so I got a $30 PNP credit!)

New fuel pumps can cost like $150. If it's a short, a kill-switch can be installed for like. . .$15-$20. (wire, switch, tape, fuse)

good luck, and PM me if you need more advice. I don't have much to give, but I know that every little bit helps.
