U1016
my car will not start, it keeps cranking and seems to not be getting any spark.
it will start if i floor the gas peddle but it sputters and reeks of gas.
FP is fine (60PSI) while cranking, IBPW averages 30.6ms,
fuses are good, relays are clicking and battery voltage drops to 9voltswith a new battery.
i was getting P1626 but it has not come back.
i am getting U1016 consistently.
i can scan/log and upload/download my RR but i can not retrieve the calibration/VIN with the tune.exe,
it says flashscan is not connected.
i thought it might be VATS because of the P1626 but, i logged GM.STATE02
and VATS Fuel Disable is Inactive.
i now suspect some kind of ground or connector wire has failed. (where?)
any suggestion is appreciated.
