Fuel pressure was a steady 8 lbs. the vent is free.

Valvetrain is good. About 2/3's thru the tow I was able to get her started. Ran around a little near the dock, then put her on the trailer.

Either the module is getting hot and going on the blink, or it's a connection issue. I'm going to find a TBI distributor, and get her set-up.

what coil are you running and how old is it?

Mike,

It was a brand new Merc coil.

Upon deeper inspection, I found that the module had lots of corrosion coming out from between the terminals within the connector base. I guess it's had some water intrusion.

I went and picked up a MSD 85551 (not so much an MSD fan any more but this worked), changed to a weather tight connector, locked the advance, ripped out the Merc stuff, and got her back up and running in about an hour or so. Timimg is locked at 30.

I ran her for a few hours yesterday, and no issues.

tom,glad you did not have a damaged engine and that you are up and running.try setting your total advance at 32,i think you will have a happy engine with a little more advance.

I was thinking the same thing... thanks for confirming my thoughts Mike!
