I just bought this 2002 suburban 5.3L 2wd, and about two days into my ownership the suburban wouldn't start, i tried to jump it and still no help i was getting desperate so i put a couple of gallons in it and then it started right up, and now i have noticed that everytime the guage goes below 1/4 of a tank the truck won't start, so i have been keeping it full for the most part. The weird thing is that if i start driving the truck and the guage goes below 1/4 of a tank it will still drive until the low fuel light comes on then i go fill it up. I have no idea why it is doing this, i have been reading the forums and some other poeple were having similar problems, they have been atributing this to the fuel pump. But i used own a F150 and when the fuel pump would go out on it, it would studder then die, not just fail to start. Please help

 

this problem could be one of 2 things:

1. the needle on the fuel gauge is mounted improperly (if when you fill up completely the gauge goes over full this is the problem) many vehicles have a tendancy to drive on "empty" before actually running out of gas
2. the fuel line from the gas is faulty (you may need to replace the gas tank)

good Luck
