We have a 604 crate and use the MSD pro billet HEI 8365 distributor with the module that has the adjustable rev limiter in it. It ran fine last year and one race this year. It started shutting down a couple of times during a race or while just sitting there idling and now it quit (could have jarred it hitting the wall once) and I can't get spark to the plugs. I put the MSD cap, coil and rotor on my chevy truck and it ran fine so that rules out those parts. I put a new module in it but still can't can't get it to fire. It has battery voltage going from the switch to the cap. It originally came with the 83645 module but the replacement now is an 83647. Is there something else I'm missing? I ohmed the pick up and it says 820 which is withing the MSD range.
Thanks,
