Archived 06 lost power, running rough

[BLinton]

06 dodge 3500 lost power and is now running rough. Codes I got were:



P 0299 Turbo/supercharger underboost

P 2509 CM/PCM Power input signal interm.

P 2146 Fuel Injector group I supply voltage circuit



Any ideas how to fix this problem?

Could be bad fuel, water in fuel or fuel filter clogged.

ok, we found out that injectors 1,2, and 3 are not firing. Any ideas on what could be the cause? Was told at one point that the ECM was out because of a bad battery, is that possible?

I could be mistaken but I think injectors 1,2, and 3 are on the same bank from the ecm.

If you have low batt voltage that could cause the injector issue
