Chevrolet fuel pump
Chevrolet fuel pump failures are a common and growing problem. These defective fuel pumps can cause a stalling condition or a no start problem. This is most common on Chevrolet truck models from 1996 to 2003 model years. You can go on any automotive forum and see people discussing this far-reaching problem. Replacement of the fuel pump is not a quick or easy job due to the fact that the pump is in tank mounted and the fuel pump is replaced as a unit. The replacement parts for the job are also not inexpensive. To make matters worse, what I have seen are repeat failures of the replacement unit. I have experienced this myself and again I have seen it many a times on popular automotive repair forums. Chevrolet fuel pump failureRunning the vehicle out of fuel, which will actually run the pump in a dry state, can shorten this. Gasoline is a petroleum product and actually lubricates the inside of the fuel pump. The more you run the vehicle low on fuel or out of fuel, the more damage will occur and the quicker the pump will fail. When you buy the replacement parts from Delco, which is the recommended procedure. They will sell you a fuel pump module. This factory replacement unit also includes the fuel level gauge sender, hanger assembly and tank filter.
Most aftermarket replacement pumps just include the motor itself. This means that you just replace the motor and transfer over the used fuel pump stock, fuel sending unit, and hanger assembly. This process leaves more room for error and is also a large cause of repeat failures. But I have experienced repeat failures, even when using the direct expensive replacement Delco fuel pump module. I found a technical service bulletin that addresses just this problem. I made a short video that reviews this exact technical service bulletin.
Chevrolet fuel pump technical service bulletinThe Chevrolet service bulletin states that the cause of the repeat failures is due to worn or damaged electrical connectors at the fuel pump assembly. When you get the Delco replacement parts it comes with a new connector on the fuel pump side. The problem is the connector on the vehicle side of the harness. Chevrolet states that this connector needs to be replaced along with the fuel pump assembly.
Failure to replace the electrical connector on the harness side will cause an excessive voltage drop across the new fuel pump that over time will damage the new replacement part. Replacement of the harness connector is a fairly simple operation and the parts are readily available from your GM dealer parts department. With the cost and difficulty of the repair, it is wise to follow this technical service bulletin and take a few extra minutes to replace the connector. In my own personal experience I have had no comebacks since employing this new procedure.
