    Feel truck has has something going on for sometime. for months back when i go to start it sometimes it doesn't crank so I've bumped the sterter with the key a few times and will start. yesterday I went to start it and acted like batteries were died even though it was on the battery tender. so I put the charger on it and came back to it 15-20 mins. later and it started. let it idle for 20 mins.or so and moved it about 150 yards to load a car (its fitted as Rollback towtruck) loaded car and moved it back to where I was before and went to move another rig while I left it idling. 10-15 mins later I didn't hear it running and went to check if I forgot if I left it running or not and the key was in the ON position so I must have left it running and it died. Now I get dash lights and can hear injectors/relays check but nothing when I try to crank.

    Today I cleaned all battery connections and checked all fuses , pulled the IDM relay and trade it with another and it started! then I got stupid and pulled the IDM relay while running to see if it would kill the engine and it did and I'm back to square one and it won't crank again.

    I pulled these codes from dash and not sure what they mean?

    Those codes are all from the body controller reporting loss of communication. I think you are on the right track with the engine losing battery power or ignition power. The engine itself allows it to crank. So if the engine is not booting up at key on, it will not crank either. Follow your battery supply harness from the batteries as far as possible. Check all connections for bent, spread, burnt, melted or corroded spots. Since you pulled the IDM relay and now will not start, check that area for anything sad with the wiring.

    Thanks for the reply Heavyd. will dig in deeper to the wiring as soon as I get time and weather. I can't get under the truck right now because it"s to low or I"m too fat! ganna jack it up so I can go chase the harness down.
