I have 2007 dodge dakota p075 code

Hello, let's start with the "gear selector won't go into park or neutral". Is it physically impossible to go into those gears? Is the shift mechanism loose and not firm into selected gears? Explain more of what you mean here. This is the reason very likely that you have no crank. Trouble codes represent stored events from a system that has malfunctioned. But the car must be running for the events to be stored -- so the codes are very unlikely to be able to answer what is causing your no crank issue.
