Motor Wont Turn Over/Starter Won't Engage?

[Wreckful]

I have a 1991 Accord, 5 speed, 2 door. Body and transmission has 350,000 miles, motor has about 120,000.

For about 4 months when you turned the key to start the car, you would hear what I presume was the starter "click" very rapidly. If you just continued to hold the key in the start position and listened to the wonderful clicking for about 5 seconds it would finally turn over and start, every time. I took off and reconnected all of the starter wires assuming that it was possibly a bad connection, and while that did help a little (it'd click for 2 - 3 seconds instead of 5 - 7) it never really completely got rid of the starter issue.

About a month and a half ago the starter clicking issue magically completely went away for about 2 weeks which was exciting, until one day I went out and she was as dead as a door nail. You turn the key and various dash lights come on, the brake lights, head lights, interior lights etc etc all work and you can even hear the fuel pump kicking on to prime the system so everything is getting juice, but nothing happens when the key is turned to the ignition position I.E. the starter doesn't engage and the motor doesn't turn over.

So far I've replaced:

- The starter with junkyard starter that was "tested good" by the junk yard. Is there a way I can run a hot wire to it and see if it engages so I can test it for myself? Could I do this test while it's on the car? Where would I connect this wire?

- I took out and examined the Main Relay because it's a common issue for them to be cracked after 25 years of sitting under the dash, and they've been known to cause non-start conditions. Mine looked great, no cracks or anything BUT I replaced it anyway with a new one just to rule it out as a possibility. Didn't change anything.

- New battery

- Checked and rechecked the connections going to and from the starter. Unless I'm missing something they all look pretty darn good.

- Ignition fuses in the under hood fuse box, they all look great.

I'm at a loss guys. What haven't I checked or replaced? Could it be the ignition switch? What else would cause the motor to not turn over/starter not engage? HELP!

Thank you in advance!

If the starter tests good do you think its the ignition switch?

Clutch interlock switch
Starter cut relay

What order should I try these suggestions in?

In the order listed, preferably.

You can jump the 2-pin connector for the CIS to see if it will start.

You could swap/test the starter cut relay to see if it's bad.

You should also check and see if you're getting voltage on the blk/wht wire from the ignition harness. That's the one that leads straight to the solenoid on the starter, after it passes through the starter cut relay I believe...I'll have to double check that one.

Also check fuse #9 in the underdash fusebox.

Edit: The blk/wht wire from the ignition harness is actually before the starter cut relay, so if you have voltage on the ignition harness side, but not on the starter solenoid then you have either a bad relay or an open in the wire.

Do this before you do anything. Look under the dash at the clutch pedal. There is a metal tab coming off the clutch pedal that engages a safety switch when it is depressed. This tab is supposed to have a plastic stopper in it. Sometimes they break and fall out and there is nothing left to engage the switch. If its gone there's your problem.
