Well I got this code once before, but some time ago. I was running stereo off the battery too long and went running down the rode in level 5 (yes I have edge juice with attitude). I figured out what the problem was. However I have had this same code come up twice in the past few days. Has edge came up with a fix for this yet? It has been doing it after I restart my truck (after running into the store or something). Engine temperature is still above 174, actually at operating temperature. Code is as follows: P2146 Fuel Injector Group 1 Supply Voltage Circuit

Anybody have any new info on this?

 

usually a loose wire on one of the injector harnesses. first check all the connectors on the side of the head if still does it remove valve cover and check to make sure all the injector wires are not loose
