Hi all, I have a 2005 Ford Focus 1.6 TDCI which an intermittent hard to start problem.
When the problem is occurring, the engine will turn over and begin to fire but then suddenly drops off without starting. It will turn over a few more times without any sign of firing before repeating the previous. Eventually it will start. It seems to happen more often than not first thing in the morning, however it has been noticed that if the car is parked in the sun it will start first time. Once it has started, it will start first time all day long.
The battery and starter have been confirmed as good. Extensive diagnostics have been carried out on the diesel system with no faults found. ECU and throttle position sensor have been replaced with no improvement.
Any help at all would be most appreciated.Thanks
