Was driving down the road and engine just shut off no warning. Car has spark so changed the fuel pump, filter, and oil pressure switch. I checked the relays and the relay switch in trunk all good. Not sure where to go from here please any help is good thanks.

Ok, your not getting spark so you changed fuel components? If it isnt your security system that has caused the problem (if equipped). Is there a transponder on the key? I would most likely suspect a crank position sensor. When they go bad you will lose spark and injector pulse. Do you know if you have injector pulse?

Ok, You need to check to see if your getting power to the pump when the key is turned on. Get a test light and check for power at the connector immediately after they key is turned on.

Does this car have an inertia switch? I think it may be in the truck on the side behind the carpet. See if there is one and make sure the button is pushed down.

Have you tried using a jumper wire at the fuel pump relay terminals to see if you can manually get the fuel pump to turn on?

Do you know where your data link connector is (OBDI)? Take a paper clip or wire and jump the pin 1 and pin 4 of the data link connector and see if you hear the pump turn on.

Also Oreillys sells a ford OBDI reader for $32 that comes with a book. Should have a digital display on it.
