Re: A while?
Ahhh... Its not quite that bad. Actually my '83 sat for 3 years and Its the nicest driving bronco I've ever had/been in. If I had to guess why its not starting, I'd start with fuel delivery. Carbs tend to dry up from sitting and it can be disasterous on small motor carbs like lawn mowers and small bikes, where passages can be as small as .03" . but with that goofy 2bbl you've got alot more slack. you might try putting a small amount of fuel in the carb, two "shot" sized amounts should get some reaction if the ignition system is working. If it hits then obviously its a lack of fuel, after sitting two years the fuel system will need some time to prime it self - but I suspect you've ground on the thing more than long enough to do it. You may have a clog in the fuel system - which would most certainly be at the Sending unit/Pickup, there is filter screen on it that would easily clog if the tank has rusted. If you don't get anything out of priming the motor, pull a spark plug wire, and stick a screw driver in the boot so it is touching the connector, place it within a 1/4" of some exposed steel on the truck, a header should work, you or you're asistant should crank the engine over, look for a spark bridging the gap, if there is one, or you or you're assistant is shocked (And assuming someone hasn't molested the Distributor or Sparkplug wires while it has been sitting) you'll have to go back to looking at the fuel system because you're Ignition system should be fine. You could disconect the fuel line from the carb and have someone stick it well into a bottle necked container, crank the motor, for 10 seconds at a time and let it be for a minute, after two or 3 attempts you should have fuel. If you don't you should look into replacing the Fuel pump, It could still be a problem in the tank but, Id replace a fuel pump before I droped a tank. If you do get fuel, then the trouble is in you're carb, go to the the parts store and pick up the inline fuel filter that screws on the float bowl of the carb, the gasket, and pickup 2 or 3 cans of Carb cleaner, that take the carb apart and use the annoying little red thing the spray the cleaner into EVERY orrifice, set the Idle mixture screws to 2 1/2 turns out, and replace the filter. with any luck it may run. I'm not going to go into every possibility, but tell us what happens and I'm sure someone will tell you where to go from there.
