If the starter will not crank the engine, then yes, it is possible that it may have to do with the Clutch Pedal Position (CPP) switch. Then again, maybe not. I t also could be a problem with the security system not recognizing your key, or it could be even more simple like a loose battery cable connection. Without proper diagnosis, I would not even rule out a bad starter motor or starter motor relay.
The place to BEGIN diagnosis on this problem would be to scan your onboard computer network for possible fault codes and verify Powertrain Control Module (PCM) inputs from both the ignition switch and the CPP switch. Also check for battery voltage at the "S" terminal (small wire) on the starter to see if the signal from the starter relay is getting to the starter (with the clutch pedal depressed).

THERE IS A STARTER SOLENOID LOCATED UNDER THE HOOD ON THE RIGHT FENDER WELL. CHECK TO MAKE SURE YOU HAVE BATTERY VOLTAGE ON THE LARGE RED WIRE ON THE LEFT SIDE OF THE RELAY. IF SO USE A TEST LIGHT ON THE SMALL TERMINAL, YOU SHOULD HAVE POWER TO THIS WIRE WHEN HELD IN START POSITION HAVE SOMEONE HOLD THE KEY IN START WITH CLUTCH PEDAL DEPRESSED WHILE YOU CHECK FOR VOLTAGE AT THE RELAY WITH A TEST LIGHT. IF YOU HAVE POWER THEN THE SOLENOID IS BAD
There is no "clutch relay" on your vehicle. However, there is a starter relay which is patially controlled by the Clutch Pedal Position (CPP) switch. This is not very likely to "not work" just because the engine is hot. The starter relay is only engaged when the ignition switch is in the "START" position, so it does not get hot as a result of normal engine operation.
assuming that your batetry voltage is above 12.4 volts,
this can be related to natural/safety switch/relay. if it is broken it only clicks but does not allow you to turn starter. you need to replace that relay/swtich. if there is a brake pedal related circuitry on your car, yo need to control that circuit too. same applies for clutch pedal for US orginated manual transmission equipped cars. without pushing clutch pedal it wont start.
another reason for this can be the stuck starter due to corrosion or mud on it. hit it with a mid size hammer gently few times.
SOUND LIKE FAULTY STARTER CLUTCH INTERLOCK SWITCH LOCATED NEAR THE UPPER END OF THE CLUTCH PEDAL OR YOU HAVE A FAULTY STARTER RELAY.CHECK TO SEE IF POWER GOING TO THE CLUTCH INTERLOCK SWITCH WIRES WHEN CLUTCH PEDAL PRESS DOWN. IS YES SWITCH IS BAD.IF NO POWER GOING TO CLUTCH INTERLOCK SWITCH YOU HAVE FAULTY STARTER RELAY OR BLOWN STARTER FUSE.

Clutch Start Switch
CAUTION Before replacing the clutch switch
or any component connected to the vehicle's control computer,
disconnect the negative cable from the battery.
After replacing the switch, slowly work the clutch pedal and note
any unusual noises or interferences with pedal movement.
If the switch is adjustable, make sure the clutch pedal height and
push rod (free) play are correct.
Then check the release point of the clutch.
Begin by engaging the parking brake and installing wheel chocks.
Start the engine and allow it to idle.
Without depressing the clutch pedal, slowly shift the shift lever
into reverse until the gears contact.
Gradually depress the clutch pedal and measure the stroke distance
from the point the gear noise stops (this is the release point) up to
the full stroke end position.
If the distance is not within specifications, check the pedal
height, push rod play, and pedal free play.
If the distance is correct, check the clearance between the switch
and the pedal assembly when the clutch is fully depressed.

Loosen the switch and adjust its position to provide for the
specified clearance.
hi,
set the parking brake and make sure its in neutral then
try to bypass the ignition switch by jumping the starter relay under the hood. take the small wire off the relay and use a 2 foot piece of wire to go from the positive battery terminal to the terminal on the starter relay you just unplugged. if it turns over and if its a manual transmission the clutch pedal interlock switch may be busted, on the clutch pedal theres a small switch that senses the pedal is to the floor and it wont start. you can try to bypass that with a simple jumper wire. lastly if neither of those do it then you may have to drop the steering column and put a new ignition switch in it.
I suspect the starter solenoid,mounted on the starter was 'stuck' on the engaged position.operation in the condition you describe has caused it's failure.starter needs to be replaced.
you have civic SI type R with the K20A engine and 6sp transmission? correct?
yes the clutch is adjustable.
loosen the clutch pedal position switch(lower of the 2 switches) locknut and back off the clutch pedal position switch.
loosen the clutch push-rod locknut and turn the push-rod in or out to get the desired height and stroke of the pedal.
tighten the push-rod locknut
with the clutch pedal released, turn the clutch pedal position switch in until it contacts the clutch pedal.
turn the clutch pedal position switch in an additional 3/4 to 1 turn.
tighten the clutch pedal position switch locknut.
loosen the clutch interlock switch(the upper switch) locknut and then the interlock switch.
press the clutch pedal to the floor.
release the pedal about 1/2 in. from the fully depressed position, and hold it there. adjust the position of the interlock switch so that the engine will start with the clutch pedal in this position.
tighten the interlock switch locknut.
clutch pedal stroke should be: 5.1 - 5.5 in clutch pedal height should be: 7.76 in
if adjusting the clutch doesn't help with the transmission feeling notchy, may be the syncros.
