Engine will not fire, coil questions.

[In The Ten Ring]

My truck has the original 250 six cylinder engine.

OK. Dad and I tried to start the truck just now.

What we know (dad used his tester).

1). Wire from coil to distributor is good.
2). Distributor points are not stuck.

What we need to find out.

1). Will a bad condenser prevent a coil from firing?
2). Can a coil "go bad" just sitting for 12 years and not being run?
3). Could we have a wire grounded somewhere?
3a). Where all might a wire be grounded?

*We don't see how it could be a grounded wire, truck drove to where it is now, it hasn't been moved from my garage, there is no evidence of any mice or other animals, and I haven't touched those wires.

Still, a grounded wire is our biggest fear.
