But my all my lights and accessories are still working. It could be the starter solenoid got stuck in the cold weather plus not enough cranking power from the battery? Should I replace the battery first? And what is the interstate battery model?Wow, that's low. Pretty much anything below 12v is discharged.
I can’t tell if the battery or starter motor/solenoid getting stuck when cold. I called tow truck and he connected a jumpstart from his portable jumpstarter and I still can’t get it to start. He removed the jump cables and told me it probably the starter solenoid get stuck and he left. After after he left I kept turning the key and finally the car started with a little struggle in the beginning. So I don’t what is going on. I am leaning toward bad starting motor.Did you try jumpstarting? I had similar issues last year and almost changed my battery but it was just the extreme cold. Bought a Jump Starter with battery pack from Costco, problem solved

Actually the 10.9v reading was on my OBDII scanner but it was actually 12.44v when I used a voltmeter at the battery terminals. I hate to say it but I may have to order denso starter from rockauto $185Battery should be 12.3+ when the engine is not running. 11V is pretty much dead. When was the last time you changed it? Get it recharged and load test it to make sure it's still ok.
Before the unplugging the dipstick. I plugged back the dipstick and the fuel trims seem to be running lower than it was unplugged.Mine is starting well in 6F too and its not a new battery either.
Is this before or after you ran the car with dip stick open?
Recently the temperature dipped in the teens and with the battery drain from the OBDII madeHow long have you had the OBD II dongel? If its been there for long why would it drain now?
Does the port get any charge when key is out? I had a HUD connected to the port and it switched off after few seconds of swicthing the car off, so I am not sure it draws any power when the ignition is not on.
