It's a combined sensor; so very possible.

If it is a Bosch system up to late nineties, then the hot start is usually controlled by a relay which is black and in the engine compartment. This prevents the system overfuelling and when the relay is dead, the engine overfuels when starting from warm/hot and engine effectively floods and it takes repeated turns and sometimes the only way to start it is to leave it, or hold the throttle open which is not great. If the car does catch, the emissions warning light goes on due to the excess fuel being cleared from the system.

Thanks very much for the advice.
I replaced the engine coolant sensor (£16 part) last Saturday and the car has behaved perfectly since.
Fingers crossed it's fixed
