Just throwing it out there if it were the inhibitor switch wouldn't it say on the display 'Put it in Park. You could test starting it in Neutral. If nothing is showing there all I can think of atm is battery cable and startermotor and relay.
It cranks but not starts or doesn't crank at all?
Just to get you warmed up
even though it's not for your Model you can still use it for reference and change to your vehicle.
