Melted wires in fuel tank 97 silverado,please help

redriderajb · 01-24-2007, 04:26 PM

I own a 97 silverado 1500 4*4 with a 5.7L. The wires inside the tank, from the sending unit down, have compleatly melted and broken connection. Anyone with any experiance with this problem? I would love to hear from you! Thank you.

Sounds pretty dangerous. Have you taken it off road and possibly bottomed out and crunched the wires so they shorted out on the way to the tank. I'd get that fixed as soon as possible

Yeah, this is dangerous.

But wouldn't your fuse be the first to go before the wires??

THANK YOU FOR THE REPLY! I have never had any blown fuses and I have not been off road in some time. The only time I drive the truck is to go ride motorcycles or a trip to the dump every once in a while. The truck only has 100,000 miles on it. I have had too many problems with it and it seems like I am under the hood more then behind the wheel! Water pump,alternators,injector spider service,complete upper and lower intake manifold set just to name a few. The wires and connector compleatly melted about a month ago , so I drilled out the top of the sending unit and hard wired everything in and now it seems to have done it agin. I do know someone is watching over me! For one I am here to tell the story, and each time has been less then one mile from home after a 100 mile ride into the desert. Any other idea's?

yep i had this problem when i had my 97 gmc. i replaced 2 pump sending unit combos and then i found out the wire on top of the tank were shorting everything else out. i had to replace the plug and i think it fixed everything i sold it right after that.

very common problem usually causes fuel pump to go. Never run truck below 1/4 tank. pump is designed to have at least that much to stay cool. makes pump last longer. this is the reason the new models can not change just sending unit you have to change it all in one piece

Yeh very comon problem even had recall on the 2001-2003 suburbans and alot of them have melted wires never seen one blown up but believe it is because of improper air mix with the fuel. The pump draws high amperage and melts wire at the poor conections the recall came out with new connectors.
