Jack up car and pull RF wheel. Put a socket a breaker bar on the crank bolt, and put the handle of the breaker bar against the ground. Have a buddy floor the gas and start the car (flooring the gas wi stop the car from actually starting). The starter motor will break the crank bolt loose for you.

A safer way to stop the car from starting might be to just unhook the fuel pump fuse/relay, or disable spark
