disconnect the starter from the solenoid and push the starter button too see if the solenoid is clicking, if youre grounds are good and the solenoid clicks, but there is no power to the starter side of solenoid, get a new solenoid, if it doesn't click when pushing the starter button check the wiring for your starter button, make sure the solenoid is getting 12 volts to the little post when pushing the start button!
