Two problems related to tank assembly have been reported for the 1999 Chevrolet Silverado. The most recently reported issues are listed below.
Abs pump was energized when I started vehicle and continued to run even after I turned off the key. Only way I was able to stop pump was by removing abs fuse, causing my abs system to no longer be active. Chevrolet said this was a common problem. Also fuel gauge will intermittently register no fuel after filling up and while riding even when the tank is full.
Gas gauge is ereratic at best. Shows no fuel then pops up to full. Sometimes indicates 1/4 tank of fuel. . In reality, the fuel tank is empty. Has caused us to run out of fuel on the highway several times.
