Engine doesn't start sometimes.

Seems to crank for longer than other identical models.

Cranks a few full revolutions before it fires up.

Owner advised it is getting worse. It starts every morning, drive into town (15km), switch it off somewhere for a couple minutes and then it won't go.

Sometimes have to just try again and it fires up, other times they are stuck there.

Starter motor, crankshaft sensor and battery had already been replaced previously.
