Here are a few things to check, did you get good fuel at the station first of all, next check if your fuel filter is good, you might want to get a fuel sample if you take the filter off and that will tell you if your fuel pump is operating when you first turn the key on, make sure there are no sources of ignition any where close as you no doubt will spill some fuel doing this. Hope this will help.

tennisshoes is on to something. It has happened to me. If you can get some gas out, especially from the bottom of the tank, by taking it from the rail, put it in a glass jar and see if gas floats on water. Also go back to the station and ask if anybody has the same complaint..problem being they will probably deny any complaints but you can try. If worse come to worse, there may be a way of finding other people that bought gas at the same place. How? Yikes I don't know but if possible..


thank you tennisshoes and davidh25 ill post what i find out. you guys have been helpful

Sounds like a bad fuel pump. If it was bad gas, I would expect to see stranded cars all around the station. Either way, it sounds like a fuel problem. An ignition problem wouldn't let it start a couple more times.

Ten is on to something. It's like its building pressure at key on but as soon as it starts the pressure gets consumed and the pump isn't keeping up.
