Will not START

I'm not sure but have your battery tested. When your clock resets, it's from a voltage drop to Zero while cranking. Dropping below 8 volts while cranking, I always considered a red flag. Okay, it performs better in the afternoon because driving it recently recharged the battery. But setting (longer) overnight it has time to lose power. That's what failing batteries do because of internal shorts dragging it down slowly. If that battery is more than four years old, it is ready to go out. Tell us how it works out. Eager to learn.

Very pleased to say that a new battery does wonders to engaging and starting vehicle. Your answer helped to ease the thought that it may be a ECM unit. This was the first time I have had any issue with starting the Ram. Very glad that the battery has been exchanged and next week's camping trip is still a GO!. Thanks Hornet.

Thank you for your reply. It's always nice to hear that I got one right. Enjoy your camping trip. Be careful along the highway. Be safe.
