the truck i have is a 1993 D250 replaced motor a month ago it has a 5.9lt 12 valve cummins turbo in it. It just stopped running 4 days ago. had battery tested it was fine. the shop that did the engine said i have a 1 year warranty on the engine but im not sure if its that or not. Truck wont crank. replace the ignition and have power to everything but it still wont crank. not even the wait light comes on. but the turn signals lights and everything else works. I need to get my truck up and running asap. any suggestion on how to fix it. the truck has done this 2 times now once last week and now this past saturday. we replaced all the fuses that were bad or look like they were going out replace the terminals. it has a new alternator on it. im not sure what else it can be.

 

Check all the wires going to starter, get starter tested at your local auto shop, to me it sounds like a bad starter, but i could be wrong. start there bud. if all the lights work etc, but wont start, more than likely its just a bad starter
Let me know what happens bud, good luck

 

nuetral safety switch maybe?
