This is a very simple system, but only a voltmeter will tell you what's
going on with it. Ignition switch terminal 50 supplies voltage to the 86
terminal of your starting relay. Is it getting there? Is the 85 terminal
grounded? Does the relay operate?
The relay supplies power from some nearby voltage source on its 30 terminal
and switches it to the 87 terminal. Is there voltage on the 30 terminal?
Does it successfully switch to the 87 terminal?
Does the voltage from the 87 terminal reach the 50 terminal on the
starter? Does the starter solenoid engage?
Does voltage from the battery reach the starter main post? Is there
excessive voltage drop between them? Does connecting a jumper cable
(car-starting type) from the starter case to chassis ground improve things?
If the electrical stuff is all good, what's left is the starter. The
starter for a/t has an internal front bearing, so a worn bushing in the
bell housing is not an issue.
If your shop does not know how to diagnose this then they ought to be
ashamed of calling themselves auto mechanics.
