Question about 1992 Honda Civic
Let's see if I can explain it. Pretty simple start circuit, but starting issues are very common to Hondas and Toyotas of the '80's and early'90's. Lots of guys used to rewire their start circuits with new wiring and relays from ignition switch to the starter solenoid just to stop those no starts.
From the ignition switch is the black/white start wire, it is hot only in start, goes direct to the "starter cut relay"- a 4 pole starter relay, the black/ white wire (black with a white stripe) is both the power feed and the coil power to the relay. Before the wire enters the relay it is spliced. one wire goes to power feed at relay, other wire goes to coil side of relay. Here's where the clutch switch comes in: the clutch switch acts as the ground for the relay's coil side. Okay, you turn key to start, power goes to the relay on both the power side and the coil side. When clutch is depressed, it grounds the coil side of relay, this energizes the relay, so power goes out of relay on the power side, as a black/red wire...and goes direct to the starter solenoid. Somewhere before it reaches the solenoid, it turns back into a black/white wire. But nothing else is in a wiring diagram for your start circuit. Buy a can of CRC electronic cleaner. Spray all connectors in the start circuit. Pull off the solenoid wire at starter-that connector. Also the starter relay , pull it out and clean the relay terminals where it plugs in. Get all clean connections in the circuit. If no help, swap in a different relay. If still no help, get a voltmeter (or a test light), when the starter doesn't want to work, check for power at the starter solenoid with key held in start, and clutch depressed. If power there, the solenoid is the problem. If no power, work back to the relay. Pull relay out. With key held in start, two terminals for the relay should have power-the coil plus side, and the power feed from the ignition switch. If both have power, may be the clutch switch not grounding the relays coil side. If no power to relay, check the start wire out of the ignition switch.

Sometimes the problem has been the ignition switch power to starter. If you have checked that, then:
This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

The starter should be located on the left side of the engine. That is the side nearest the front of the car. Typically the transaxle spans a portion of the right side of the engine. You may also find related info on tha Autozone website. Enter your vehicle info then go to "view job diagram" on the right side of the page.
