My bike runs with the MAP sensor tube off??
So I've got a ZX12R 2000-01 A1 that has had fuelling issues. I have a other thread open at the moment but it's got a whole load of other stuff on it now and the situation has progressed.
All sensors work, all wired go to the right place, ECU is good, Fuel pump is good and engine is good.
With all as it should be it wont start. If i remove the tube for the MAP sensor so its measuring atmosphere it starts immediately and revs up with the throttle. It runs super rich and bogs if you're not gentle with the throttle. If you have it running and reconnect the tube back onto the sensor it dies immediately.
Has anyone got any idea what the problem might be? I'm thinking possibly the fuel pressure regulator but its just a guess really.
