2011 Dodge Grand Caravan. Daughter's car. Intermittent no start condition eventually became a never start condition. Engine turns over fine but won't start. When it was still an intermittent problem, I thought it was the infamous TIPM fuel pump relay problem, so I tried bypassing the relay with a jumper from the power outlet fuse to the fuel pump fuse. That worked for about 2 days, then the problem re-appeared but now it was starting and immediately dying. I was not present to witness this condition. So I'm going to start over with the basics, listening to see if the pump runs with key on and go from there. I am anticipating needing to know one thing: On the pigtail that delivers power and returns data to/from the pump, which of the 4 pins should be getting 12V on? I found one wiring diagram online (Automate) that identifies it as DB/OR. Is that correct for this year and model? I'm going over there Wednesday to start looking at it again.
Well this is really stupid. The battery failed finally after all the cranking and recharging. They bought a new battery, and the problems disappeared.
