Alternator Problem?

I have a 1972 F100. It ran the battery dead, and now it won't start, it'll only turn over.
The battery is brand new, and I've tried jump-starting it.

sounds like you have more than one problem. if you can't jump-start it, then something is wrong in addition to the dead battery.

you're gonna have to take it from the top-
are you getting spark to the plugs?

well- if you've got spark and its in time...then it sounds like a fuel issue.

so, a couple of questions:
1. how did you verify that you have spark?
2. have you checked the timing? to do that- rotate the engine until #1 is at TDC on the compression stroke. then check the timing marker.

ok- we'll go with what we've got.

if it ran for a couple of seconds and then died- i'm leaning towards a fuel issue.
have you got a can of starter fluid? hit it with a quick shot (a couple of seconds) and try it again.

I would also look in the carb while looking working the accelerator to see if your getting gas to the carb. Might want to get alt checked out.

How did it run before battery when dead. Wondering if your getting good spark, have you checked the points.

Belt ? / Timing Chain/Gears ? (Timing set replaced or?)

Did you leave the ignition on by chance? Possible the condenser has failed, but if you have spark ?? good spark or orange in color ?

Check that the points gap is correct in the distributor (a match book cover on at points gap on the lobe is ok for gap test to start)

GOT FUEL ? I assume your not in a vacuum! With a CHIT LOAD OF SPARK AND FUEL!

If you have a starter turning, good battery and fuel... I would lean towards an issue with the distributor.

If the starter is turning very slow, good battery, then it could be a coil or your points and condenser not working properly.

Get a multi-meter and start testing your volts on the various components, with regards to starting the vehicle.

That would be my input.
