I need help! My 2007 dodge 2500 4 wheel drive with 5.9 cummins is showing a code. I went ot autozone had the code read and it come out that the ecm/pcm intermitten power input. What does this mean and how do I fix this?
Does this mean I need a new computer for the truck?

 

Check the code yourself with the key trick https://dodgeforum.com/forum/2nd-gen...code-list.html. Then post the code that comes up in the 3rd gen ram section.

 

Painted,

Please post code and I can look it up for you.

 

I went to autozone and the code they gave me was p2509. I called dodge dealer and they said it was my battery or battery connection. I have checked my batterys and every wire that i can find. This made no differience. Two days later the light went off. The truck runs great but has no fuel milage. This has been 3 days no light , today after sitting all night, I started the truck, when you turn of the key all is well, when it gets to the start postion it sounds like a electric fuel pump rattling as it trys to start, truck starts runs great engin light is on. and bad fuel milage. I also done the key trick, The engin light flashed 10 times. thats all it did not give any info.

 

Painted,

This sounds like a 3rd Gen/Diesel related question.

 

I have tested batterys and connections. This morning I went to start the truck, turned the key the starter hit did not turn the engin, all lights and bussers went off. should I post in third generation?

 

Or the diesel section......
