My extended cab would not turn over. I put in new spark plugs and wires. New distributor cap, fuel filter, fuel pump , strainer and new EFI relay. I sprayed starter fluid in the intake and the truck would run for about 5 seconds then shuts off. Do anyone have any other suggestion on what I should try next.

In your diagnostic box short FP and +B. This when the key is turned on will bypass the Circuit Opening Relay, which controls the fuel pump. This will bypass the COR and turn the pump on when the key is turned on, then try to start it. If it starts then you probably have a bad COR.
