Motor won't crank. Shift in P but dash showing Drive. Jumped, still nada

What is your question?

Engine light came on three weeks ago. Code said either vacuum leak or O2 issue in Converter. No decrease in performance so I ignored. Tranny coolant line is leaking slightly at fitting. Several months ago I could not remove key when shutting off engine. I wld hv to turn key to On position and move shifter back and forth thru gears until car recognized tranny was in Park
