Had a small fleet up til last year and had an 09 Volvo with the same engine, it started acting the same way and after chasing the problem before finally determining it was the ECM I decided to go ahead and start with the ECM this time, but that hasn't solved the problem just yet, even with the 2 new engine harnesses. We'll check those spots for sure. It passed the bang test but KW is going to bench test it in the morning regardless. We jiggled wires, checked fuses, just about everything you can think of. My harness doesn't go around the back of the engine like the pics I saw, but it does go around the front, and it's brand new now. And my fuses are on the firewall and not in the battery box. By the time we were done monkeying around we were no longer getting power from the ECM. The truck ran and shut off on its own 3 times during the days events. | |||
