Question about 1997 Jaguar XK8

Open Question

1999 xk8 conv. engine in fail safe mode or not starting,

Sometimes the car will not start after showing a warning TRANSMISSON Problem but after waiting for a while will start; at other times it will switch into FAIL SAFE MODE with restricted engine performance shortly after having started and driven for a mile or two- eventually it will come back to full power after a few miles or 30 min- basically unpredictable and repeated behaviour. it twice has cut the engine on the highway with complete loss of power- barely able to make it to the emergency lane and stop. Once the engine cut after the air conditioning suddently seemed to have stopped.
meanwhile i have come to realise that something has not been ok with the cooling system. Can one make a mistake after refilling the system-airlock??? since i had to repeatedly top up the coolant but now seems to hold the level?

What causes my 1998 Jaguar XK8 not to start when initially cranked and the Fail Safe message is displayed?

Is the check engine light displayed? If it is, that's where you start, by retrieving the fault code(s). If not, then you could have a security system fault, fuel system breakdown, etc. All codes, regardless of the systems affected, will cause the vehicle computer to immediately default to a failsafe mode, till the problem has been fixed, and this drastically affects driveability, causing no-start issues, idle problems, etc.
