1996 GMC Suburban Fuel system Problems

“We have a 1996 6.5 turbo diesel Gmc Suburban. We had severe stalling problems. The dealer replaced the fuel pump at their cost and installed at our cost, new glow plugs, glow plug sensor, battery, and battery cables suspected to be the problem. It continued to stall. We returned to the dealer and they replaced the pump again at their cost, but we had to pay to drop the tank to check for contamination. There was a deteriorated screen we paid to replace. It still stalled. Only this time it stalled when I was going 50 MPH and approaching curves along the river. …”

“It is a well known fact that there is a defect with the fuel injection pump on the GM 6.5l diesel engines. I have had a number of these pumps replaced by GM at their cost. However, the problem is not getting resolved. These vehicles die intermittently. When they die (stall), you loose your ability to control your vehicle with the loss of steering and braking (for the most part). There have been numerous times when I have almost been involved in an accident because of this issue. It is extremely dangerous when these vehicles die because of the pump problem. …”

“While replacing the fuel pump to try to fix my problem, I found the power wire (gray), melted inside the fuel tank. Maybe it grounded out somehow, but the whole wire harness is burnt, and the wire is brittled and burnt.”

“Vehicle shuts off while driveing GM knows of problem and has replaced injection pump and pump mounted driver 3 times so far GM special policy c00064 for 11yrs or 120000 miles. The same problems still exsist I have a 9 passenger in order to take my kids and friends to sporting events on one such occastion. The truck shut off without warning a tractor trailer was behind us thank god he was paying attention and no one was hurt. This is a serious safety problem that is nation wide for 6.5 turbo diesel owner. Dt”

“Fuel pump failed, upon inspection of the unit mechanic found that the insulation was burned on the wiring inside of the tank. We have had this none functioning fuel system problem for over a year. This was the first time it completely quit and would not start. It would seem to me that amp draw enough to melt back wire insualtion insde the fuel tank should be fuse protected! Last time the truck would not start the dealership we use in clinton mo ( raysick Gmc, clinton mo) towed the truck in and once inside it started. But the truck has left us stranded numerous times before.”
