I was driving down the road and the car acted like it shut off. I was able to start the car again and go. Then it shut off like it was out of fuel.

I replaced the fuel pump and started and was running horrible. Then gave it gas and it shut off and would not start. Placed it on a computer and showed miss firing. Replaced plugs wires and coil pack. Still Will not start. Was told it could be the cam sensor. Replaced it and the wiring to it. It Will not start.

Has 60 lbs of fuel pressure has spark and new battery. Any ideas? Could the gas be bad and have water in it?

You replaced the battery try a security system reset then if still runs badly scan for codes. if it still runs like badly and has a misfire have a mechanic fix that as they are very hard to find. now as it can be a basic engine problem. injectors or any sensor.
