[tropical36]

Cranks over
No power to ignition
No dash display
Fuses good
No power on one ECM fuse
No power to auto park, etc.
Mobile tech suspects ECM

start at the battery, replace it with something, clean ALL PARTS of the connection and remove the FRAME GROUND and clean, then see what you got. easy first hard stuff next.

When did problem occur?
Is it possible you have an Interlock system(s) that is disabling Ignition power?

If you have no power to one ECM fuse, why would he think the ECM is bad? I would try to find out why there is NO power going to the ECM.
This could be a dirty connection, a broken wire, or a rodent chewed wiring harness. You have power to the ignition switch, other wise it would not crank. I believe coaches of that vintage seemed to have a problem with the ignition switch going bad and burning up internally because of so much power being drawn through it. Check all of the power going in to and out of the ignition switch as well as the connectors coming out of the steering column.

If there is no power to ecm then it is not ecm sounds like you have a bad connection or a bad main fuse somewhere. Power missing to all thise things is generally NOT the ecm
