So an update, I believed the truck was losing prime, causing the no start. I thought I had the truck fixed after several attempts and parts replaced in the fuel system and Davco filter assembly.
When traveling over spring break, I had another no start in a Way-Mart parking lot. No matter how much I pumped the primer, I could not get the truck to start. When the truck failed to start, the Autoshift display would blink the red service lamp.
I was able to contact A L B Diesel and Auto repair, and after explaining what I had been experiencing with the intermittent no start, Stan diagnosed the problem as electrical not fuel related.
Some time in the life of the truck, the 12volt leads from the battery to the ECM and TCM, someone had connected them using wire nuts, and not solder and heat shrink.
Once the leads were soldered back together this no start issue has not returned.
Thanks A L B Diesel,
Michael
