Hello, i am having some issues with my 2006 focus mk2 1.6tdci. While driving the engine cut's out the glow plug light flashes with the oil and check engine lights on, i turn the car off, if i try to start it up right after the incident it will crank but will not start. If i leave it for a while it will start and work perfectly fine. i took it to a mechanic, he changed the camshaft and crankshaft sensor, still the problem persists he checked the instrument cluster in the dashboard and it still does this. This all happened after i changed it's alternator. could it be cause when the first alternator broke it shorted something inside the car? Has anybody else experienced this?
