Please help my grizzly cranks but will not start. Diag shows code 13,15,21,22,41 . Cant figure this out. The ecm and wire harness are brand new. When the key is turned on and switch set to run the injection system does not receive signal from ecu to activate fuel injection system. The bike will start if i pour fuel in intake while cranking therfore i have ruled out spark.
