91 C2 will only run on one coil

[dougn1]

my car started acting up the other day and got progressively worse untill it wont run at all.

some experimentation has yielded the following strange results

it runs smoothly if i drive the secondary distributor with the secondary coil. it runs albiet roughly when i drive the primary dist with the secondary coil

it runs smoothly when i drive the secondary dist with the primary coil. it wont start when i drive the primary dist with the primary coil

it wont start in the normal 2 dist/ 2 coil condition. (it tries to start but doesn't)

if i drive the coils with each others drivers, nothing happens in any condition....so there is a difference at least in the way the coils are driven

who really knows how this system works???

Simple question, but is the belt broken? I realize the symptoms don't reflect this, unless you have the primary and secondary confused.

no the belt's good
