Initially the bus would not start. Replaced the Cam and crank sensor and the bus ran fine for a day and would not start again. We then replaced the harness and the bus ran fine for a few months. Now the problem is back. Does anyone have any ideas?
Get your voltmeter out and check refrence voltages at the sensors, and grounds. I don't know if this is a circuit that shares these voltages out of ECM or not, but very well possible.
