Is there power to the (+) side of the coil with the ignition switch "ON", meaning power is getting to the ignition switch and SHOULD be available to the section that activates the starter?

The "start" wire leaving the ignition switch will be PURPLE. Is it "HOT" when the key is turned to "START"?

If there's power that far, next voltage check is at the neutral start switch on the top of the steering column down near the firewall (AT) or at the clutch pedal switch (MT) (IF used).

The purple wire then continues through a firewall connector and down to the solenoid on the starter.

It's ALSO possible the solenoid or starter has failed. (If the starter brushed are worn out, there will be NO current through the "pull-in" winding in the solenoid and the solenoid won't engage.)

Sometimes, giving the starter a sharp rap with a plastic mallet or block of wood will jar the worn brushes into contact with the commutator, giving one last start and proving the problem is the starter.
