| Dt: the automobile would not start. no previous problems, this was the first incident. the consumer assumed it was the fuel pump. an independent mechanic came out to inspect the vehicle. he determined the fuel tank sending unit assembly had caught on fire which melted the wiring inside the fuel tank. there were no visible flames, when this incident occurred was unknown. he was unaware of this problem and would have not known unless the mechanic had pulled the fuel pan bed and discovered this failure. the mechanic offered no explanation as to why this happened. the plastic simply melted, and the wiring was burned. there have been no repairs or corrections made at this time. *ak | |||

| Problem #1: the fuel pump relay doesn't seem to disengage after first starting the engine and it heats up. this causes rough operating of the engine. further investigation shows that the maxi fuse to the lighting system heats up also, but does not fail. another area that is affected is the mini fuse to the courtesy lamps. it heats up, but does not fail. the last area to be affected is the evaporative emission canister vacuum switch. it acts as if the wheels are out of balance around 50mph. i have taken this vehicle in to the dealership on a number of occasions and they either can't find anything wrong or try and tell me that the fuel injectors are at fault. they put injector cleaner in the fuel tank on two occasions, which made it run worse. i asked to have the injectors replaced while it was still under warranty and they said they had to follow procedure bulletin #00-06-04-003 before taking that step. the problem still existed, but they haven't offered to replace fuel injectors. my thinking is that the problem is really the ignition switch. can you please advise me of any other similar complaints and how it was resolved? probelm #2: while driving straight highway at about 55 mph steering feels loose and wants shift lanes on it's own. on sweeping turns it turns to the right on it's own. i had the front end alligned and a new set of tires, but the problem still exists. any advise? | |||

| For several months, the truck has been cutting off unexpectedly while driving. this is extremely dangerous as it loses power steering and is very hard to control. it has cut out in the middle of busy intersections as well. gm is aware there is a problem - they recently sent out a notice claiming they were extending the warranty on the fuel injection pump. however, when i took the vehicle to the dealership they refused to fix the problem. not only that they refused to sell me parts so that my mechanic could fix it. i am now stuck with a $35,000 truck that is not safe to drive and i cannot get repaired. | |||

| This fuel injector pump was replaced 5 months after the purchase of this truck in july 1997 at 11,232 miles on the odometer. in sept of 2000 the same problems started again and was taken to dealership. they said they could diagnose it unless it was doing the stalling out, so we proceeded to drive the vehicle as it was our only means of transportation. on dec. 26 we had truck towed to dealership to have the same part replaced as was done in 1997 only 5 months after we purchased this new truck. this part as told to us by chevrolet and the dealership they had a special policy # 00064 - our ref # c02653123 thru chevr. was told that there should be no problem in replacing the part again. now they are renigin on it. said we were over our miles - 120,000 or 11 yrs. the part was going bad at 118,187 in sept., but we kept being told by the dealership that it was not showing up and was probably bad gas. we took it 3 times and they never documented it only fixed other problems. now that the warranty is out, the truck has completely stopped running and they refuse to honor replacing the part that should have been done in sept. so here we are in the middle because of the dealership mechanics refusing to believe it was that until they replaced a water sensor to be able to put the computer on it to verify it and we had already taken it to 2 other mechanics that told us that was the problem and to take it to the dealership since it was a bad part that they were having trouble with since 1994. no one imformed us of this... now we are faced with a bill of over $1700.00 to replace this same part that we knew was bad and we were under the miles of our warranty for this, but since the dealership mechanics said that was not the problem, we kept driving it since it was our only means of getting to work. we need help... thank you for anything you can do for us. *ak | |||
