I am having lots of trouble with just starting the car, I have changed out the Fuel pump and other items, I have run a computer check on it and it says the computer is the problem after changing out the other items first. Could this be the problem just change out the computer.

First, to answer your question, yes, the PCM could be the problem, but lets not take that and run quite yet. Your post does not really detail exactly the problem, or the list of steps you have taken thus far. There are, with any problem such as this, a great number of things that could be the problem that are more common, and more probably the failure. I'd suggesst that you get ahold of a repair manual that has a diagnostic tree to follow, and follow the suggestions there to rule out the more common failures.

Best of luck to you.

If the car has hit a bad bump or something like that, there is a fuel pump reset switch in the trunk on the drivers side at the very back. It should be yellow.

I had this problem with a mustang and the pump had shut off after a bump.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
