172 cup wont start, coolant temp light flashing

[Daryl*]

Hi, i just jumped in the car to go and buy onions and it wouldnt start, as far as i can work out its the coolant temperature sensor but i want to be sure.
This light flashes on the dash

Immobiliser sometimes stays on and sometimes doesnt, Im not linking this to the problem i have as it sometimes comes on anyway, even when the immobiliser light is off and this light flashes it wont start.

Also is this the coolant temp sensor?


Thanks for any help.

That is the engine management light flashing. Needs a proper diagnostic read out/investigations.

Coolant sensor wouldn't stop the car starting mate, engine management light is on, if you have/are having immobiliser problems have you tried to re-code the keys via the guides on here?

The light next to it came on for a while (electrical light?) but it's started working again...
Gonna get it checked out ASAP though thanks for replys
