Ihave a 2001 4964ex westernstar changed starter now truck will not start engine will turn over. Light comes on in dash that says data error
power wire that went to sol. still hooked up? fuse for ECM/ at batt. box an in fuse box panel dash blown?
what engine? if Mercedes - check wires. two brown wires - ECM grouns, two red wires - ECM unswitched power. These wires are bolted to starter... it is Mercedes thing....
