Fuel pump or bad gas??
I have a 1994 Buick Lesabre with a 3.8 V6. My problem is that one day i filled up a shell station. Traveled 50 miles and it died on me. I tried to start it but to no avail. I waited 2 or 3 minutes and it started. But as soon as i push the gas it died again. I had to wait 2 minutes again. I started it again so i decided to let idle up to speed. It was fine then. I could push the gas gently andit was fine. Until i slowd down and tried to push gas again andit died. I checked the fuel filter it was clean but i replaced it anyway. Several months have passed and now it runs good except when i rev up the engine as high as it will go, it revs up and down every liike its running outta gas but it doesnt die. before i check the fuel pump.....do you think it could be bad gas?? ( the gas station closed down a week after that day)

I think you can forget the bad gas theory. You already drove 50 miles before you had a problem. It's not likely to be the gas. You could have a fuel "pressure" issue though. It needs to be tested at the time the problem is occurring. You need to test the fuel pressure, spark at the plug and injector pulse at the time it won't start. You could look at the fuel pressure now but the other things will check OK until the problem is a total "no start"
