Sounds like fuel pump


The fuel pump is located under your backseat you cant access it from there but, what u could do is put your ear against the back seat around the middle of the seat, have someone turn the key on and off a listen for the fuel pump, they are quite loud with your ear that close, if you dont hear anything chances are it is fuel pump, there is a fuel pump relay in the front under the hood in your fuse box, however with all the miss fire codes u were getting and the fact that it wont run now, tells me its the fuel pump, low fuel preasure can cause misfires, it has happened to me.

Thank You, I removed the tank and replaced the fuel pump. I also replaced the fuel filter. The car started right up. It took a few miles for the engine to stop running rough ( less than 10). I had to clear the misfire codes again. now it is running OK
