   Hi everybody I was wondering if anybody might have any ideas my vts is only firing on 1 and 4 (its sparking on 2 and 3) it is showing 220psi across all 4 cylinders and its had new plugs, It doesnt fire even with a little easy start in the inlet, could this e an ecu fault? or am missing something?

   Has it got the correct coil on it?
   
   Black connector must have black plug coil, grey connector must have grey plug coil.

   see if the injector wires have enough length to swap them around, 1 to 2, 4 to 3.
   
   If it still runs on 1 & 4 but not on 2 & 3 it's a mechanical issue (maybe head gasket across the middle).
   
   If the fault moves to the other cylinders, it's an electrical issue.
