Just had my van MOT'd and serviced, and the garage inform me that it will now not start. I have had a couple of problems with the immobiliser before in that the 'Lock' light stays illuminated and the ignition switch will not work, I usually get around this by pressing the fob button a few times and it eventually works. But this time, the ignition is turning the engine but the immobiliser is not letting fuel through.
I have given them all the keys I have, but none of them seem to deactivate it. Anybody had any similar problems?
It is a 1997 Fiat Ducato 2.5D. (Compass Drifter Merit 310).
