Eight problems related to fuel pump have been reported for the 1997 Chevrolet K1500.
My 16 yr. Old son purchased a 1997 chevy K1500/silverado w/ 5. 7liter gas engine; 160k+ miles. Previous owner explained the truck was on its third fuel pump. Sure enough, the fuel pump failed on us also at 163,000 miles. Fortunately it failed only 100 feet from home as he drove down our residential street. Imagine the hazard potential had it died at highway speeds. Towing and repairs totaled $800. A remanufactured pump (with 1 yr warranty) was installed plus a new fuel filter. The dying fuel pump shed debris that clogged the filter which starved the engine. A google search details how people have experienced problems with chevy fuel pumps in trucks ranging from 1991s to 2002s; perhaps newer if I searched longer. I can ill afford to replace a fuel pump like that again. With the history of fuel pump failures well documented (ref: google search), why hasn't chevy engineered a fix years ago??.
Over the past 5 years and 80,000 miles of owning this vehicle the fuel pump has died on me 5 times. All 5 times the pump was replaced with ac delco parts from gm. The last two times it went out I had it replaced by a chevy dealer in tampa. The second to the last failure caused a domino effect that ended up being very costly to me. Fragments from the pump traveled to the filter, somehow made it past the filter and ruined the fuel pressure regulator. Fragments from that traveled further along and destroyed the throttle body metering valve and all 8 fuel injectors. After having all this work done, the last fuel pump only worked for about 6 months before it went out again. This time it luckily did not ruin the above mentioned items. There is obviously a problem with the gm part being defective, and it's not something the consumer should have to put up with as routine maintenance. I've never let the tank get below 1/3 full because I know it can damage the pump below 1/4 full. The pump fails without warning and has caused a danger to myself as well as other drivers on the road.
The power supply connector to fuel pump inside the fuel tank at upper end of pickup/fuel pump support tubes burned hot enough to soften the copper connector causing it to open up and shut off fuel pump causing engine to stop running. Approximately 2 inches of wire insulation was melted off at the top connector end. This is inside the fuel tank surrounded by fumes and fuel. If air was introduced there would have been an explosion. This is the factory installed fuel pump and fuse did not blow even though the wire was exposed and near metal components. I've owned the truck since new. Richardson brothers Chevrolet in floresville, texas and other auto part dealers informed me that this is very common and have seen worse damage to wiring. The dealer wanted over $400. 00 for the parts which include new pickup tubes with fuel level float and fuel pump. I'm a quality control inspector for aircraft and this would have grounded the entire series of that particular aircraft. (twa flight 800).
I would like to make this complaint very clear and to the point. I have been viewing the complaints located on your website and feel that there is a significant pupose for recalling these vehicles. I purchased a 1997 chevy k20 approx 1 1/2 years ago. Everything seemed to work fine until a few months later. I started to experience some steering problems. It does not matter if I am driving around a corner or straight but the steering will become very loose and veer into one direction all on its own. That is just one of the significant problems I have experienced with owning this vehicle. I now have come to find that there is even a greater threat to my safety and that of my family because I have now been informed that my fuel gauge and fuel pump wires, inside the gas tank, melted insulation and burnt the connector. This could have been a deadly experience for myself and that of anyone that could have been in the vehicle with me if it would have caught fire prior to my knowledge of this information. I feel that the first sign of this problem is that the gas gauge will start to malfunction, which leaves you guessing at the amount of gas in the tank. I feel this matter needs immediate attention due to the fact that owners/drivers of vehicles are required to carry auto insurance, however, this is something that none of us has any controll over. If we wait until someone becomes involved in an accident, that would seem senseless that possibly someones life would have to end before this situation be taken seriously. I have to demand that some action be taken before it is too late for someone.
While driving engine stopped and would not start. Had to be towed, mechanic said it was the fuel pump filter sending unit. Fuel pump was not running, and wires in the tank were getting hot and melting whick could cause an explosion.
Fuel pump failed after ruling out that the relay was o. K. The vehical was towed to hallowell Chevrolet at roadsides assistance and informed me that all costs would be taken care of but due to the warrantee had already expired,per the dealer, I was stuck with the cost regardless of the mileage.
Shortly aftet warranty had expired fuel pump went out. Service personnel mentiond problems with fuel pumps that if tank was ran empty pump would overheat and fail. Suggested that we not let fuel tank get below 1/4 tank as to keep pump cooled.
The wire inside the fuel pump shorted out, leaving an exposed wire inside the fuel tank. Dealer is inspecting the vehicle.
