The crank sensor is just below the Alt; on this engine and perhaps the wiring harness to the Alt has been pulled and they did not notice ? Clutching at straws yes, but it has to be something as simple as that .... Engine earth strap has also been suggested but he engine revs OK but stalls/cuts out after 2-3 feet !!!

Hello there, the crank sensor is on the other end of the engine by the starter motor, I couldn't imagine that this is the cause, first check the security of the battery terminals and the connections to the alternator as these will have been the only things to be removed while replacing the alternator, if something there is loose then a power interruption as the engine lurches will cause it to cut out.

Also check around the air filter and mass air meter for loose hose clips as this will have been removed as well, but there maybe the possibility that the fault is unrelated to the alternator change, it may be worth checking on another type of scan tool as some may not pick up manufacturer based fault codes.

Please let me know how you get on, regards, Vauxdoc.
