Did you check for voltage at the starter? Did you try cranking in neutral? Any testing of the starter circuit, make sure the tranny is in park or neutral and a functional e-brake is set.
The purple wire at the starter solenoid S terminal, should be hot with key in the crank position. Use a digital multimeter across battery posts, have helper turn key to crank, whats the reading?
