It sounds like a fuel pump problem. When you first turn the key on you should hear the fuel pump run for about 5 seconds then shut off. There is a fitting on the fuel rail on the engine that looks like a tire valve, try pushing on that to see how much pressure there is after the pump runs. There should be a good amount of pressure on it. If fuel just dribbles out or there doesn't seem to be much pressure it is definaly a fuel pump. The best thing is to use a fuel pressure guage that will attach at that fitting. There should be between 45 - 60 PSI of fuel pressure when the pump is running. Good luck with your problem.

Turn on the key and listen by the fuel tank for the fuel pump to hum. A common problem is low fuel pressure. It will build pressure when the key is turned, use that fuel, and then the pressure drops. Kind of like when you're using a squirt gun that's getting empty.

Keep it simple and replace the fuel filter first, if thr fiiler has not been replaced within 30,000 miles or 1 year. Then it's a good chance that it's going to be the fuel filter.

Acting like it is out of gas


Sounds like a bad fuel pump, that's exactly how they act when they die.

It's usualy inside the gas tank so it's a dealership type of repair, you got to pull the tank, and sinc you filled it, it's eithe got to be drained, or use a transmission lift to get it out, NOT a home job unless you've done it before and own a hydraulic lift

It sounds like the same thing that happened to my sons car. He was driving home from school and it just died on him. It acted like it wanted to start but would not. He replaced the ignition module and now it starts. He was gotting power from the coil to the distributor, but not from the distributor. Good luck
