I have a 2006 model 4.3 mpi with an alpha, I have the motor out of the boat to replace the head gasket, all the work is done and it is back together. The motor will spin over, but not start. I tested it with the DDT and when doing an injector test injectors 3,4,5 and 6 are not firing. I can switch leads from injectors 1 and 2 to the other injectors and they will fire, so I don't think it is an injector problem and i have have good fuel pressure at the rail. The motor was running before i removed it. I am thinking I have a sensor plugged in wrorng or am just missing something stupid, any help would be greatly appreciated. Serial number is OW634777
