No, seems as tho it should start, acts like a gas rig that is out of gas, the first time it happened was right after starting, about 15 seconds later just died, started back up and on the way home about 5 minutes stopped at the corner, died again. start again easy also, couple seconds crank and fire. home and park overnite, morning try to start about 1/2 seconds, felt like it was going to fire, pop, and then just crank. Hope to put that insight in this AM and maybe it will show a code, if not will have to start running the T/S guide I pulled off this site, Don't know much about all the add ons on these motors but have been round tractor diesels for a few years. Always thought fuel, air timming and these things fire, way too many electronics on these motors for an old fart to keep up with, I do have a pretty good mech that understands some of it tho. got my fingers crossed
