If it started after you put on the new its either your coil or the ignition module. It's always a good rule of thumb when you change rotor and cap you should also change wires/ plugs/ and coil. I used to have one of these trucks and had then same problem. Gave it a tune up and fired right up. Also, don't forget about vapor lock. Good luck.

i did the correct firing order when putting the wires back on... but yea the igniton module was what i was thinking... because it did start then when i gave it gas to go forward or backwards it stalled out and died...

+1 on the pickup coil.
I know you stated your fuel system is fine but something else I've had to deal with on our '93 Chevrolet shop truck was a stuck float in the tank. One of the shop techs put a fuel pump in and about 6 months later it would start, run for a little bit(about 10 minutes), and die. Then wouldn't run for the for the rest of the day. The next day it would do the same thing. The fuel system seemed fine. The fuel guage showed it had fuel and the injectors had a nice pattern. Added 5 gallons to it after checking everything else and it ran just fine. Come to find out the float for the fuel guage had gotten hung on a baffle in the tank.
I'll check to make sure when I go to work but I think there's an oil pressure switch to cut the fuel pump relay. It should be located behind the distributor. The fuel pump relay switches over to the oil pressure switch after the engine starts.
