Electrical problem? Need help
I have an 04 Cummins I've had for 3 years. I've had nothing but problems with it. Found out the guy I bought it from was racing and pulling with it. It had a programmer on it but isn't on anymore. Long story short I've had a codes popping up out the ***. These are the codes I have, P2121, P2127, P2123, P0201, P2127, P0202, P0203, P0204, P2509, P2146. It's a lot. I'm not sure if this could be all a computer issue or a lot of wiring issues. I did lose my gas pedal once so I think the sensor may need replacing. The rest I'm not sure about. I don't know where to start. Any help would be appreciated

Knockout P2509 first. Check all battery connections and ALL grounds. Make sure they are clean and tight. See what your alternator is putting out, get your batteries tested, check all the plugs on the bottom of your TIPM making sure there is no corrosion or broken pins and do the same for the ECU plugs.

As somebody already stated start with the P2509 resolution and see where it goes from there
