Recently my hummer has been having problems starting when its cold. I've tried gas treatment after thinking it might be the water freezing in the gas line. This has occured about 7-10 times so far. After the initial crank, I wait 15-20 minutes and it starts just fine. Any ideas?

check your fuel pressure it should be 50-57 psi. if it's lower than that then change the fuel filter first as it could be a pump.you shouldn't have to worry about waterin the fuel line as most fuel sold today has 10% alcohol and it wll allow the water to go through .
