Check the timing.

Before you check the timing you have to disconnect a wire that is hidden underneath your carpet where the front passenger would put their feet...close to the firewall. It has a clip that easily lets you disconnect it.

As for the wiring diagram for that truck, you will need to buy a repair manual (Hanes, Chilton) from your local auto part store. It is several pages long, too much to try to explain here.

If you changed the distributor, you should also have changed the rotor and spark plugs. Also check your plug wires for arching. Make sure the wires are not touching anything metal. If they are not secured right, they will wear out very quickly from rubbing around.
