Porsche 991.2 - engine turns over, but won’t start !


PCGB Member
Hi All,

After 4 years of faultless ownership, my 991.2 Carrera t failed to start.

battery fine, fuses checked.

fuel is getting through to the engine, as you can smell it after 2-3 engine cranks.


I noticed that the vehicle temp display shows the coolant temp at 90C, even when the car‘s engine is stone cold and been Sat overnight.

Does this point to a faulty coolant sensor being the culprit ?

Any thoughts welcomed as will
get it recovered to a garage.

Thanks J

Just incase anyone suffers similar issues, it was indeed a faulty coolant temperature sensor that needed replacing. Relatively straightforward job to replace, but got to drain the coolant first, of course.
