Answer
Jimmy,
  I'm NO TECH. That is stated in my Profile but I will offer a couple of thoughts for you to consider.
  You didn't state when the truck had a tune up so I'd begin with the basics, cap, rotor, plugs and wires. You might look at the air filter while you have the hood up.
  If that doesn't help, you might look at the fuel system again. You say the fuel pumps are working but there is a specification for fuel pressure and volume. Be sure to have that checked also. While the fuel system is open, you might connect a professional cleaner to the fuel rail and clean the injectors directly. This is MUCH better than pouring something in the tank.
  That's about all I can think of for now. I hope this gives you some direction and a solution to your problem. Good luck and Happy Holidays.

Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you. I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire. If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle. PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you.. Skip
