These 4.3L W motors are common for fuel leaking inside the plenum causing them to run rough and smell like raw fuel. The fuel pressure regulator leaks internally, also the injector spider leaks and the two fuel lines feeding the fuel to the spider. You have to remove the plenum and look for the clean spot. Where the fuel leaks it cleans the oil off. Before you try this check your EGR valve. The EGR valves on these get stuck open with carbon and cause a rough idle. Remove it and look for the plunger it is a small round piece that you can push in and out, make sure it closes fully. You can also clean it with carb clean and they make a replacement gasket with a screen in it to keep chunks out of it. Start with the EGR because it is easier. The parts for under the plenum are available at most any parts store. If you have any problems just ask, and if you can not find the parts I will give you part numbers. Let me know what you find I will be back tomorrow.

It sounds like the return fuel line is leaking. There are two fuel line and one is the high pressure line which goes to the fuel pressure regulator then to the fuel rails. There is then a return line from the fuel rail to the gas tank.
With the amount of fuel leak, it's going to be the return line since it's not that bad compared to the high pressure side. Follow the fuel lines from the drivers side around the steering shaft to the engine. The high side and low side (return) run side by side and you should see it leaking when the engine is running.
Good luck and hope this helps.

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.
