Cummins 450C No Start (Data Link Inactive)


Tried to start my Starboard engine. Key On there were no lights on the display panel. Specifically I look for “Wait to Start”. Digital display turns on after system checks and says “all systems ok” even though no data is on the screen, then changes to “Data Link Inactive. The analog gauges for voltage indicate 13.5 volts and Fuel is 3/4. Oil and Temp gauges are constantly moving. Engine will crank strong but not start.
I’m Leaning toward a broken wire or dirty connector at this point but not sure where to start. Any thoughts out there?
