THE DIAG FOR THAT CODE IS HORRIBLE
I WORK AT A GM DEALER, DO YOU SELF A FAVOR
REMOVE THE CAM SENSOR AND CHECK THE MAGNET ON THE TIMING GEAR SEE IF IT FELL OFF, MAY HAVE
BUT THIS WILL NOT KEEP THE CAR FROM STARTING
ONLY SYNCS THE INJECTORS TO START.
MOST OF THE TIME WITH THIS CODE AND HORRIBLE FLOWCHART THAT GM HAS, REPLACE THE CRANKSENSOR,PCM, CAM SENSOR TO COVER ALL BASES
BEFORE YOU DO MAKE SURE FUEL PRESSURE IS CORRECT , ALSO CHECK INJECTOR PULSE, AND SPARK
IF YOU DONT HAVE PULSE OR SPARK COULD BE A CRANK SENSOR OR WIRING PROBLEM
