Car won't start, possible fuel problem.

Heya,

I have a 1991 Camaro RS V6 ATX. Yesterday it ran out of gas, and I had to run home to get some gas for it. The gas had been sitting in a 5 gallon can in my garage for maybe 2 months, we used it to fill our lawnmower. I ran back to the car and filled it up (probably around 4 gallons) and tried to start it.

It started up, but sputtered and hesitated and any pressure on the accerator caused it to stall. The fuel gauge reads a little above a quarter tank. Eventually after stalling out so many times it just refused to start. We pushed the car home using my Mom's car and left it outside.

I just tried to start it again (almost 12 hours later) and nothing.. The engine turns, and you can smell gas, but it just doesn't want to start. Something I had noticed is that the distinctive whine of the fuel pump is missing.. When I put the ignition into the "on" position before starting it I can always hear a whining coming from the rear of the car, which I have been told is the fuel pump warming itself up. I can't hear it anymore. What the hell happened? Did i just suck up a lot of sediment from my fuel tank and clogged the lines up? Or is the fuel pump shot?

Any help would be much appreciated, thank you very much.

it needs gas to cool the motor, and no gas=fried fuel pump

Yep, ya goofed up your pump motor. I run mine down to the top of the red 1/8 make and then put in another 5 gallons. I only buy 5 at a time. though a full tank is better for tank life. They usually rust out on top from never being filled.

You could try adding 5-10 gallons of good gas to water it down if you think that gas is bad.

so you either have to drop your exhaust/rear/tank and get at it, or cut a hole in the floor hatch area. i like the hole idea as its less work. some people dont like it.

How do I check my fuel pressure without taking it to a shop? You think the pump is fried because I don't hear the whine?
