Thanks for helping. My truck turns over but wont fire. I changed the plugs, cap, rotor, starter, fuel filter, air cleaner, but it wil not start. When I put it on a battery charger the starter spins a little faster and sometimes after turning the motor over for about 5 minutes it might start. I was thinking it was the fuel pump, but im not too sure. Everything else seems to be ok. Thanks for you time

If you have that spider fuel system, they are known for problems. Can you check fuel pressure? Maybe the fuel poppets are sticking?

Have you done any basic testing? Have a helper crank it, while you check for spark at the plugs. If you do alot of testing with the engine cranking, you may need to disable the fuel system. If you flood the system it will make it harder to start. You may have to look at the plugs, see if their wet or smell like gas.
