check the fuel filter, then the fuel pump's there is also a cross over valve on the drivers side frame rail that controles witch tank u are getting gas from

Check for a clogged Air Filter or, quite possibly, a plugged Catalytic Converter.

To check for a plugged Cat, either:
1. Take it to a muffler shop, where they can perform a flow test on the exhaust system.

2. TEMPORARILY unbolt the the exhaust where the FRONT of the converter attaches to the Y pipe coming from the engine. Make sure to suspend the exhaust before taking it for a ride, so it does not interfere with anything or drop to the ground.

Take it for a test ride and see if that cures the issue. Remember, it will be very loud, so try to head to an area that you wont bother too many people.

try disconnecting that hose and crank the engine

most likely

in that case just check all the fuses and replace any blown ones. some fuses feed ather fuses and are not labeled as such on the fuse panel

vacume advance not working

locate your fusible link wires leading from your battery the and the electrical harness, you may not be getting the accessory power to your key switch and this is supplied via this fuse wire located near the battery

Well the first thing is to make sure the parking brake is off and that the front wheels are chocked (unless all wheels are off the ground). If the parking brake is on you will have a difficult time getting the drums off (if at all). Now, they could be rusted on but there should be two holes near about 1/4 inch in diameter about an inch from the edge, those are for you to screw bolts in to push the drum off. Find some suitable bolts at a hardware or autoparts store.

the fuel tank capacity depends on the model you have really, On 8' long bed models the fuel tank capacity is 38 gallons and the 6.75' short bed models are 29 gallons.
