Event leading to failure: I was stupid enough to buy the lemon in the first place. The failure (s) occur on a regular basis. I bought this 2001 gmc jimmy in 2004. As a certified used car. It had 38,075 miles on it. I didn't have it a month before the left front wheel bearing went out. Shortly after the pollution control air pump went out. Then it was the air filter pump and hoses to the remote filter. Next came replacement of all four brake rotors. All of this before 40,000 miles. Next came the fuel pump(april 2006).a couple of months later it was the fuel pressure regulator and fuel sensor. Then it was replacing the 2wd/ 4wd selector module in the dash. Next in line was a new alternator. Less than a year later it was another new alternator,a couple of days ago it was another new fuel pump. There are at least a dozen other things that were replaced. I only mentioned the really costly items. I have spent just a little over $5000.00 on this piece of junk. Contacting gmc customer complaints is a big waste of time. I'll never buy another gmc anything. The federal government should pull the plug and let gmc close down forever.
Vehicle keeps stalling after warming up. I've changed the fuel pump, fuel filter, coil pack, module under distributor.
Upon starting the vehicle the key would not return from the start position to the run position in the ignition. This LED to the starter trying to start the engine continuously with the engine already running until I put the shifter in the drive or reverse position. The engine would not turn off until I took out the fuse for the fuel pump. The starter would not disengage until I took out the fuse for the starter. These fuses are located in the engine compartment. This had to be done with the vehicle in drive and with the parking brakes on. I believe this is related to a problem with the wiring harness that connects the floor shifter to the ignition cylinder lock system. Talking to other owners of this model vehicle, several of them have experienced problems with their keys being stuck in the ignition. The vehicle is currently parked with the battery disconnected and the key stuck in the start position until I can get it fixed.
Failure of 15 amp. Fuse. Cause shorted bare wires in fuel tank. Attached to fuel pump. Fuel pump and wiring replaced.
Faulty fuel pump system.
Dt*: the contact stated while driving at various speeds, the engine stalled without any prior warning. The engine would not restart. The vehicle was towed to an independent repair shop for inspection. The mechanic suggested replacing the fuel pump. Additionally, the mechanic determined transmission fluid was low and the wires of the wiring harness needed to be replaced. The mechanic replaced the fuel pump assembly, added transmission fluid, and new wires to the wiring harness. Afterwards, the stalling problem persisted. Updated 4/6/2006 -
2000 gmc jimmy has had 4 fuel pumps in last year and a half just stopping while driving in traffic and 2 transmissions same as fuel pumps stopping while in heavy traffic. Wiring harness very brittle.
Dt: the contact states this is the fourth fuel pump that he put on the vehicle. The dealership repaired two of the fuel pumps, and the contact repaired the third one himself. At this point, the vehicle will not start. He contacted manufacturer ,and they offered no free remedy.
