The car does have about half a tank of gas. I noticed when I rev the engine and hold it there, that it sounds like its missing on a constant rhythm if that make any sense.

Would having a diagnotic test done at a dealer show what is wrong with it? I would hate to spend that kind of money and not show anything.

I'm assuming the fuel pump is in the tank and you would have to replace the whole thing. That I can do (I had to do it to my 12 yr old truck). To be the fuel pump would be ok with me.
