Troubleshooting assistance - No response when turning key

Put it in neutral and see if it will crank. If not, hold the key in crank position and move the shifter from reverse through to 1 and see if you hit the sweet spot.
Another quick check is put a test light on the crank wire on the solenoid while someone turns the key. If that has power check the other terminal for ground. If you dont have a ground check your neutral switch.
