    Hi all, engine went last weekend on a track day so I’ve replaced the engine with a refreshed one but it now won’t start, it’s trying to start but just won’t get there.. I have a code in for map sensor short to ground, no other codes in.. anyone had this issue before?

    It’s a 2011 engine and I’m going to check that tonight. This other engine come with a different cps and wiring on so I’m going to put my old wiring on tonight

    That sounds like a fair indicator. Afik all those 675 engines share the same type of loom connection.
    Good luck, & let us know how you get on please.

    Swapped the cps over from the old engine and it’s fired straight up!
