We purchased a used Galaxy a couple of months ago now. After the first few days it wouldn't start first time, the engine would turn over, but wouldn't fire. There was no pattern to it, it could be from cold, when it had been used, while on a flat surface, on a hill. Once it did start (which could take 2 goes and at max 5 goes) it was fine. No cutting out, smooth running. Took it back to the dealer we got it from, there were no fault codes and they have replaced the Fuel Filter and fuel filter housing, but it cut out on them the day it was meant to come back to us. They have now changed the crank shaft sensor and are unsure still if this has fixed the problem, but we are having the car back to at least try it and see if it happens again.
Anyway, has anyone had this problem or know what it might be. Feels like it is going to happen again, but just a case of when really!
