Then you must have an issue with the power to switch the solenoid, or you got a bad new solenoid out of the box. Run a 12V jumper the the switched terminal on the solenoid and see if it will then crank. If it does, you have an issue in the ignition switch or wiring to it, if it does not, but still cranks when you jump the solenoid you could have a bad new solenoid as well.
