Won't Start
 

Pulled the truck out of the shop and shut it off. Set there for about six hours. Got in to pull it back in and won't start. Initially the diesel preheat light came on as usual when it is cold, but then all kinds of alerts came up about things not working and RPM & speedometer dials go up and back down. Tried unhooking battery to reset ECM but that didn't work. Read something about the ECM fuse but can't figure out which fuse that is. Thinking we're going to have to have it towed in to the dealer and checked out. Any suggestions?

How is the battery? Fully charged?

Yes, battery is good.

Yes, battery is good.

Gonna have to plug in with a scanner, and see what's up. If you don't have one, having it towed to someone that does is your next option.

Yep, that's what we did. Fortunately we live close to the towing business and then the Dodge dealer/service center is only about five miles. Thankful for small blessings.
