1996 Chevrolet 1500: fuel pump failure

Filed Sep 4, 2013 · Fuel system · 218,931 miles · CO

I have a 1996 chevrolet c1500 originally equipped with a 5 liter which was replaced with a 5.7 liter. I replaced the fuel pump and sending unit due to the old part was no longer good. Within 2 months the new part shorted out, frying one of the wires on the inside part of sending unit, inside the fuel tank. I again replaced the part thinking I had bought a defective item the first time. I am now starting to get the same symptoms it had the last time right before the last sending unit went out. I did an electric check on the old/new fuel pump and it was o.k. The symptoms are, when I'm coming to a red light the vehicle stalls out and dies. I put it in neutral, crank it, and it starts back on. It did the same thing last time until finally it failed to start. I know of a 1996 chevrolet astro with a 4.3 liter and it also suffers from the same problem and uses the exact same part number. Any suggestions that do not involve tnt would be highly appreciated.

I purchased this truck about 18 months ago and since I have had it I have had to have the fuel pump replaced 5 times by a mechanic shop, costing over $300 each time it was done. It would work for awhile then quit, leaving me stranded in remote areas. I used to be a mechanic before a back injury so I finally pulled the full tank down and pulled the sending unit out. I noticed the gray wire going to the electric fuel pump has melted the coating off the wire and it is loose. I have ordered a complete sending unit and pump and hope it solves the problem. It seems to me that this could be a very bad fire hazard if it should happen to short out inside the fuel tank.

It was discovered that a wire inside the fuel pump which was located inside the fuel tank had melted.

I own a 1996 chevrolet 1/2 ton p/u and what happened is on my fuel pump sender a few of the wires caught on fire, obviously causing my truck not to work. I got the part replaced, but I am concerned in the fact that I had a fire in my gas tank because of this problem. The person who fixed the fuel pump sender said that he has seen the same problem in another chevrolet mini-van and has herd of this problem about other chevrolet vecihicles. He also informed me that he knows the federal safety agency has been informed of this problem. My intent in this corespondence is that you look into this problem before one of these tanks blow up. I appreciate your time and hopefully we can get this resolved before there is a major incident with these fuel pump senders. If you have any futher questions please feel free to e-mail me.
