Hey guys, I am new to this forum. I have never used a forum to receive help on my vehicle but I have used them a lot to work on my mx bike. So within the last couple of weeks I have walked out to my truck and turned the key and it turns over but seems to not be receiving enough fuel. I am pretty good with working with my cars, therefore i knew that sometimes if you kick the gas tank it will knock the fuel pump free and begin to work again. So I crawled under it and gave her a kick and she started right up. This happened twice. However, it has now quit for good. The tahoe has 120k on her and she is a 99. I have never messed with a fuel system except changing the fuel filter from the motor back. Does anyone have any helpful suggestions or steps on how to do this. I plan on digging in this afternoon. Thanks guys!
