I have the fob you turn not the push to start

 

When you turn the fob to the Start position do the indicators / lights on the cluster blank, or do they stay lit? If you try the same with the headlights on do the headlights dim when in the Start position or is there no noticeable change?

They restart and the radio goes black then comes back on…the truck acts like it’s in some type of anti theft mode and won’t let it start…I told the service tech at Dodge about what’s going on and told him I can jump the starter relay and it will fire up for about 3 seconds and he said that’s how long it will run when the truck thinks it’s being stolen

 

I remember reading about some systems that have a "car jack" mode which will allow the vehicle to run just long enough for the driver to get away from the vehicle and thief. In my mind that should be longer than 3 seconds, but maybe not. I wonder if your truck has an intermittent door ajar switch and thinks the driver's door is opening while the truck is already running. I don't recall what sequence of events would trigger the car jack mode, but it's probably something like Vehicle Running AND Vehicle in Drive AND Vehicle Stopped AND Driver's Door opens and closes.

Do your interior lights ever do strange behavior?

No the vehicle seemed perfectly fine the night I got home from work and parked it and the next morning it would not crank with all kind of service messages popping up like park sense anti lock brakes engine temp hot airbags and the radio will not play music it just shows the message turn ignition to run

 

My rf hub behind the back seat is getting 12 v with good ground…I’m not sure where to go from there I’ve checked all fuses and I didn’t do anything to the truck overnight so I’m puzzled

 

try restarting the truck with the fan belt removed? only run for a few seconds and see if the issue is resolved

 

The truck only runs for a second or 2 only if you use a jumper wire on the starter relay

 

Just bumping this thread to see if you found the answer to your issue. I'm having the exact same issue, parked it last night, and today it just didn't crank at all, lit up with every service warning, and now it's bricked on my driveway. It's not the battery.

 

Turned out to be my computer…changed it out trucks been fine ever since
