ZR-1 Net Registry Forums - View Single Post - CCM code 54 "Cranks does NOT run"! '90 MY

Marc Haibeck · 06-19-2011

The VATS control on ZR-1's is in the CCM.

Chances are that the key was not read correctly. The VATS system would lock out the starter and the fuel. Maybe in the past, someone has bypassed the start relay. Then with a VATS lockout the engine will crank but not start.

It might be best to skip the VATS repair and bypass the VATS fuel lockout. It's easy to do on ZR-1's with a modification to the engine calibration chip.

Best of luck.
