11 No crank reference signal at PCM, No crank reference signal detected during engine cranking

12 Battery disconnect, Direct battery input to PCM was disconnected within the last 50 key on cycles

17 Engine is cold too long, Engine coolant temperature remains below normal operating temperatures during vehicle travel ( thermostat )

54 No cam sync signal at PCM, no fuel sync ( camshaft signal ) detected during engine cranking

55 End of message, Completion of diagnostic trouble code display on the malfunction indicator lamp ( Check engine light)

With both an 11 and 54 be sure to check all wiring for shorting or damage, for both at the same time normally means loosing the PCM power feed to them both do to wiring or shorting sensors

I hope that this helps you
