I grounded coil positive to block?

If it wont turn over on the key then check for voltage at the starter relay to start. Usually yellow to turn the relay on. it is a simple relay that switches voltage from the battery to the starter. the relay needs a ground, and + voltage through the ignition switch to the starter relay coil "usually yellow"to energize it. The ground can either come from the case itself or a neutral start safety switch device.

And once again, no make/model or year for what you need help with! Everyone is not a physic!
