Crank sensor fail?

[Nigel Blandin]

A bit off topic, but sonny-boy’s Fiesta tdci won’t start this morning. Turning over, glow light ok, but no fuel smell from the exhaust.  
It has sat for a week. I’ll get over there and  plug in to it later, but my first thought is crank sensor.

I’ll check the fuel feed as it could have dropped back to the tank, but a fair bit of churning didn’t work.

Any experience of these motors out there? I see the sensors are cheap and easy to replace which is handy if it is this.

Sorted. Changed the sensor(£23, in stock down the road) all good now.
