Last time I had the issue I tried moving the shifter into every position when starting and couldn't get anything to go. I dont believe this transmission has a neutral safety switch. I could be wrong. If it does maybe its just not hooked up. I can't remember if I did or not...

We're not flying airplanes, we're working on 50 year old trucks.. I spent almost 35 years "in the trenches" as an automobile mechanic. Over half of those years as a "specialty tech" doing electrical and AC repairs. GM sent me numerous times to their GM Training Center in Houston, Texas, plus many, many hours attending local training seminars. Never once did the instructors list crimped butt splices as number one method of joining two wires.. There are factory splices all through an automotive wiring system, and to the joint, they're all soldered..

When you have the no start problem have you tried shifting it into neutral and see if it will start? Be sure and hold your foot on the brake pedal.....

Yep. Threw it in neutral and tried it and applied the brake in neutral - same story. I then tried it in every gear and reverse just for something stupid to try.

I even bought a can of that "freeze off" CRC I think makes it and sprayed a can of that on the starter to try and cool it down and it still took over 16 hours to start back up.

Hopefully I will time on Sunday to do some trouble shooting.

Starter heat saturation was a problem after I "built" the engine (350) and added headers to my '76 Cutlass Salon. Had to double the heat blanket due to the headers. Never had a problem after that.

As a side bar. My son-law's I/O boat had a stater problem over the 4th. After a new starter and hours of "what-the-hell" we discovered TWO additional things. A bad starter ground due to painted block (crate engine had been recently installed). AND a bad relay.

Starts right up now. That Volvo Penta 4.3 sounds like a old Harley.
