Brand new to the forum and brand new to dodge. Truck is a 2006 Cummins. I replaced both batteries the other day. Truck fired right up no problems so my wife and I decide to go get a bite to eat. About a mile away from the house the truck dies and will not start back. It will turn over but will not start. The check engine light flashes when I turn the key on. I tried to check for codes but get nothing. Done the key on-off 3 times, all I get is ------- then it says "done" Any help would greatly be appreciated.

 

Check for fuel pressure coming into the cp3(injection pump) Could be a couple of things. One the lift pump, another possiblity is a locked up integrated control module( fuse box under the hood).

 

Just got it figured out. The ground wire was loose going to the ecm.

 

Also really clean those new terminals and cables - crazy things happen with bad grounds. Also remember most new batteries are not fully charges so hit it with a slow charger overnite. I found out it does a better job individually to charge each battery separate with the cables off.
