MSD Distributor issues

Fires right up, then dies. I tried this several times, to make sure I was getting fuel.

Testing: I disconnected the distributor pigtail from the coil and measured the voltage at the + and - terminals on the coil: +12.44V. I install the distributor pigtail and the voltage at the coil terminals drops to +2.44V.

Since I have +12.44V at the coil terminals with the distributor disconnected, and it immediately pulls down to 2.44V when the distributor is connected I reason that the distributor has failed.

Am I missing something?

Get this: My original 8352 failed, but it was several years old and I chalked it up wear. Since I am building a new engine and didn't want to spend much on my current engine, I replaced the failed distributor with a Summit Racing MSD knock-off for $190. THAT unit had an internal intermittent short, and I returned it. Frustrated, I dropped $365 on an 8352 that worked fine for two weeks, then failed and required me to flatbad the Cobra home. THEN, I get this unit as a warranty replacement (Summit Racing is pretty awesome in service) and it fails right out of the box. I'm pretty fried on all of this trouble-shooting. I just wanted one more season out of this engine before I drop in my 331 stroker (which, I regret to say, also has an MSD distributor that I installed...). This has been maddening!

Doug if its just a season you want to use it for, Napa, duraspark dizzy...about 60 bucks...it will work with the MSD box

This is a very common problem.

MSD pickups are unreliable.
