Mr688 - Code 64 No Start

Recommended Posts

Any ideas? Checked continuity and voltage on all wires at VECU. Also, checked continuity and voltage on all wires at ECU. Checked all fuses and relays - all good and voltage good. Ohm'ed J1939 wires all good. Installed good test VECU and ECU still no start. Have good fuel pressure. Computer will not talk to data link. Any suggestions will be appreciated.

Low oil level or low oil pressure will also cause a no start on some systems. Paul
