The engine would usually start and run normally, and once running it did not cut out. Intermittently it would crank but not start. The owner suspected an immobiliser fault because the key warning light on the dash did not go out when the fault was present.

The vehicle started and ran consistently on the first day after many start attempts. On the second day it was driven for 2 hours on the highway with multiple stop-start events and no fault. On the third day it was driven for 1 hour in peak-hour traffic without missing a beat. On the fourth day the fault occurred, with the engine cranking but not starting.
