This might give away: jacked up rear end, put in gear and runs fine. Wheels spinning everything but as soon as you put weight on vehicle and let it down and tires are on ground, put in gear it dies. Am I not getting enough compression to move vehicle or I don’t know, baffled. Engine seems to run fine until your in gear and obviously on the ground lol.

 

Have you check compression? May not be a bad place to start, followed by fuel pressure...... Sometimes, a bad crank sensor will do that for ya as well... but, they ain't cheap, and the aftermarket fellers just don't work very well. Gotta be genuine mopar sensor.

 

Thx I will check that out. Thx for ur time.
