I have a 2002 Chevy Silverado 1500. My buddy replaced my fuel pump recently, and while he was dropping the tank he broke a fuel line, so replaced that as well. About 4 days afterwards, my check engine light came on and it said it was the fuel tank pressure sensor. I had a professional replace that, and about 4 days later the check engine light came back on and said it was the fuel tank pressure sensor again.
I ignored it and drove the truck for about 2 months. I could smell a small gas odor every once in a while. Yesterday I was leaving work stopped at the gas station and went to start it, but it wouldn't start. I had it jumped and it started, so I took it home and now neither the lights or the radio will come on, and it won't turn over: no sounds at all. I thought it was the battery, so I had that checked out, but its not the battery.
I'm at a loss as to what it could be. A day before this happened, when I started the truck all the lights turned off, so I switched them off then back on and they all came back on. The next day is when it broke down. Can anyone tell me what it could be?
