If you can hear the fuel pump whining then your fp relay is ok.

I second starter solenoid.

Sometimes the starter just gets gunked up w/ old grease and refuses to budge and can be loosened w/ a hammer whack. You can also check the wiring and connections to the starter.

It's also possible your battery is low. Sometimes there is sufficient voltage to run the fp but not that and the starter.

And maybe your ignition switch is bad.

In my car, I just decided to replace the starter and solenoid w/ a new high torque model. I figured 29 years was sufficient service and the higher torque would be better for my hi comp engine.
