Got this bus that sat for the winter, went to start and no start. started with mo crank and found ign fuse blown. then would crank but not start. Found the 10 amp fuse for idm relay blown, replaced fuse and started. Shut it off and continues to run, pulling either idm fuse or 40 ecm power fuse to shut off. All gauges and accessories will loose power with key but engine continues to run. Occasionally it will blow either the 10 amp ign fuse or the 10 amp idm fuse. I looked at and wiggle tested wires at ecm and idm. At the end of the day all was working normally but why I am not sure. Suspect engine harness or idm issues. I see no sign of rodent damage even though this was parked in a "barn" for the winter. Anybody got any suggestions, it appears fine now but I think it will return to haunt. Thanks all.
