145k miles 2014 T&C. I replaced oil cooler with the Dorman aluminum. While I was in there I did both knock sensors and put new oem sensors on the oil cooler assembly. I also cleaned the injectors and placed new orings. Test drove it and it ran fine. Next day while idling in the pick up line at school it all of a sudden started to shudder during idle but seemed fine driving home. Next day it will crank over but won’t start. I eventually got it to start holding down the gas pedal and it runs rough. I cleaned throttle body and put new intake air temp sensor and map sensor. No change. It’s very hard to start cold. For some reason if I pull the fuel pump fuse (I think M25) it starts and seems to run fine until the fuel runs out in a couple seconds. It has codes for running rich, lean and for misfires. P0174, P0172, P0300. Any one have any ideas?
I also got one of the fuel pump relay bypass wires and it doesn’t seem to change although I need to try it again and verify the connections. But the fuel pump runs when I turn the key on and I think the exhaust smells rich to me but then again it might always when it’s cold. I’m running out of ideas
