Pontiac G6 2007

Asked by GuruNBFK2 Oct 25, 2019 at 04:49 PM about the 2007 Pontiac G6 SE I4 Sedan

Question type: Maintenance & Repair

My Pontiac G6 2007 acted like it wasn't gonna
start last few times I drove but pressed on gas a lil
and got it to start, got home to drop something off
and now I can't get it to start. When I turn key it
clicks, my battery voltage is at 13.4 I added
antifreeze and am waiting for it to cool down
hoping that's the issue... Lights and windows are
working and I replaced starter earlier this year, help
me please

Have a helper use digital multimeter across battery posts while you turn the key to crank. What happens to the reading? Does it just stay the same, no drop, then there is an open circuit to starter for some reason. If the reading drops way down, that isn't going to work. Shouldn't drop below 9.6 volts or there about. The battery connections are all good? Have you tried a jump box or jumper cables? Two voltage circuits at starter motor, one comes from battery, hot all the time. The other circuit goes hot with key in crank position and the starter relay is energized. The starter motor usually grounds through the engine block. Any testing at starter motor, make sure transmission is in park or neutral and parking brake is set. Make sure vehicle can't move. Any applicable trouble codes?
