The fuel gauge on my '96 1500 has been pegged on full since I got it about a year ago, even with the key off. I finally had the time to look into it, and it turns out there's a black (I think) wire in the harness that plugs into the pump harness, coming from just under the firewall, that is melted the entire length of the harness. it's been that way a while as the exposed wire is corroded to nearly dust. I've searched but I can only find the short harness from the pump to this one? Does anyone know where I could get a replacement? I'll try the dealership on Monday, but they tend to be less then helpful. Also, any ideas as to why the wire would have fried up like that?
Thanks!

 

Why not just replace that wire? Gotta be cheaper than buying the whole harness.

 

I might go that way, but it's junk right into the connector under the firewall, and I don't know how or if that can come apart to replace one wire.

 

Need the cool little tool to remove the wire connector from the plug. I think most parts stores sell 'kits', for just such an occasion.

 

or junkyard....

 

"Pinning" (or de-pinning) tool.


Junkyard my be a better bet, although we could find out where those wires go and you could make your own.

 

I've always been uneasy getting wiring/electrical component from a wrecker. With something this week old, who knows how long it's been sitting there or if it's any good at all? I'll try to track down the depinning kit and fix the wiring myself. The toughest part will be dropping the tank to get it off the pump end. Good times ahead.....

 

Isn't there enough room to reach in, and unhook it? I can actually see the connector on my truck.....

 

Just had a flash back to 2003. I had a 95 chevy 1500, was starting to exhibit a weak battery. One day I went to start it and I saw a puff of smoke from the front of the car. I looked into it and found the horn relay wire completely bare - straight copper. The cables on that truck looked new, but when I grabbed the negative battery cable - I could feel the crinkling of oxidized copper. The starter had found ground through that relay ground. Probably should find out why it passed all that current, else you might just put a new wire on and have the insulation burn right off again.

 

i can get my hand up in there easily enough, but I can't get my head in enough to see. There's a bunch of bracketing for the running boards on one side and the driveshaft/exhaust/shielding on the other. I'm hoping that the wire rubbed through into another wire on the harness, it melted all the wires around to it as well (though I couldn't see any that were burned through to the wire). The tank should be around half or so, so it shouldn't be a huge deal to drop it, and it's still driving so I could burn off more fuel. It's odd that something like that happening didn't pop a fuse somewhere?
