Tapping the starter does not always work. I would check all the connections on the battery and starter. If these are good replace the starter. Don't forget the grounds.

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

On the firewall is the starter motor relay. There are 2 large battery sized cables to it, and 1 smaller ( 16 AWG ) wire that is orange or orange with a stripe ( forget the color, want to say white or tan ).
When you turn the key to the start position, check the smaller gauge wire for +12 V. The case should be ground. If you do not get +12 on the orange wire, try starting the truck in neutral ( apply the parking brake, chock the wheel, etc normal safety precautions ). Test for +12 V at the small wire. This is the output of the DTR ( Digital Transmission Range ) sensor or in common terms the Neutral switch. The start position on the ign switch runs through the DTR to the starter motor relay coil.
If you have a stick, the DTR is replaced by the Clutch Pedal Position Switch ( clutch must be pushed in to start ).
If you have power to this ( at the times the truck won't start ) next is to check the both battery cable ends to see if they are corroded and making intermittent contact ( not probable but possible ).

Ignition relay or fuse could be the problem. When you turn the key to start do you hear a fuel pump kicking on and or do you have spark when you hot wire the starter (I know it's hard to check while trying to start it)? You can email me back and I might be able to pinpoint it more.
