ok guys I got a 91 with a 302 mod, I just got it and the sucker wont start now.
I know it has MSD ignition system and at the coil the has diffent readings when it rolls over
I for the life of me cant remember how to fig this out
anyone got a take on my prob

 

have you tried bypassing the MSD box and running it off the computer only? I have had analog MSD boxes go bad on me before? Are you running a ford distributor or MSD?
