2015 Ford fusion SEL Ecoboost doesn't start.
My wife's fusion will not start. It's the push button ignition. Step on the brake, press ignition button, full auxiliary power comes on, dash board, radio, climate control all function. CEL is on, pulled codes for an O2 sensor, but that shouldn't effect it starting. When I continued to try and start it, CEL started flashing like a blinker light. With ignition on, it will not go into neutral.
I pulled the battery had it tested, battery is good. It is parked in a very inconvenient place to inspect it further.
Does anyone have some insight into this issue with a code for O2 sensors and no start? Thank you in advance.
Edit: dash is reading it's in select shift mode and that is in first gear, shifter is in Park.
