Answer
Hello Michael,
Have you verified that the fuel pump is producing fuel at the fuel rail? Listen with the gas cap open, or near the rear wheel well. I would expect that you should be able to hear the pump operating when you turn on the key.
If you remove the air cleaner and spray a little starting fluid in the intake and the engine starts and quits immediately, then fuel delivery is the problem.
The fuel pump relay may be your problem or a bad fuel pump. Or you may have a clogged fuel filter.
Hope this information is of help.
Good Luck
Robert
