This is now down to a now spark situation. I changed the crank and now fuel pump is working 100% but not getting a spark at the plugs. I swapped coil packs for another one I had but still behaving the same. I'm not the worlds best mechanic so anyone able to tell me in what situations the M44 doesn't spark? Plugs are new and it behaves and tries to start the same with the coil pack disconnected :(
