Greetings all!
Today something strange happened. I fired up my daily driver 2012 Ram 2500 ST w/Hemi 5.7….it idled for 2 minutes or so then I placed in drive. The second I put some pressure on accelerator pedal, the engine sputtered and died, red lightning bolt illuminated. Could not restart (just clicked like battery was low/dead)….all lights on dash and the info screen flickered and faded away, and the needles for rpm, speed, etc were all “twitching” slightly.
This happened once before while I was driving. Shop ended up replacing the engine ECM. Initially thought it was bad TPS in the gas pedal but replacing it did nothing. That was a few months ago.
Flash forward to today. After I found I could not restart the truck, I disconnected the batter negative cable from the battery for a few seconds. Reconnected it and made sure it was clamped on tight.
I went to start the truck again and this time it fired right up, no problems, no check engine lights or other error/warning lights remained illuminated - all was well.
Drove it around, romped on the gas and truck ran fine.
Why did disconnecting the batt negative resolve this?
Indicate I may need new battery or have a grounding issue?
(Plenty of red lightning bolt threads out there but I couldn’t find one like this)
Help is appreciated. I’m guessing this is a very temporary fix.
Thanks!
