Chevy Traverse won't start, starter not engaging
I have a 2010 Chevy Traverse. Ran fine on a 500 mile trip, but a few days later,
wouldn't start. Put the key in and turned it to "on" and the traction control off
light is on, the check engine light is on, the gas gauge shows empty (its not),
and there is no info from the computer such as oil life or fuel economy info.
Turn the key to start and all the dashboard lights turn off and nothing happens.
Checked battery voltage and it's 13.1 volts. Checked battery connections and
they're good. Tried to hook up my obd2 code reader, but it couldn't connect to
the computer. Any suggestions?
try disconnecting / leaving it off for 10-15 min, then reconnecting battery. Maybe just a 'hard reset' would help.
Went out 12 hours later and she fired right up, but the check engine light was on. Plugged my code reader in ( if you own a Traverse you better get one) and the fault code was U0100. That basically means that communication was lost with the ECM. Guess I'm gonna be checking connectors and grounds associated with the ECM.
I have a 2010 Traverse and the same exact thing is happening. Engine won’t start, Gas gauge shows empty but it has gas. Traction control off light on check engine light on. Please let me know if you solved your problem. I am done with this vehicle. I’ve had so many problems already with it and don’t want to take it to the dealership again now that it’s no longer under warranty.
Replace fuse for ECM 1 And for ECM if code U0100 is popping up
