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?
2007 International 4300 DT466 Allison Auto ( fitted as Rollback Tow Truck)
#5 9: 2
#6 150: 2
Any help with these codes?
