Default s2000 doesn't crank at all

Everything was working fine until i parked for a hour or so went back to try to start the car and nothing. battery is good, trying jumping the clutch safety switch, also try swapping out the relays. funny thing was i used a test light to check the ignition signal fuse and nothing, should it have current with the key on? any advice before parts changing starts

Do you hear anything when you press the start button?

Nothing, had no signs of being a bad starter ie slow crank or sticking starter. everything was fine then nothing. I really hope it's the push start button. the next thing I am going to test out just a pain to get to lol anyone else has problem with there button any flow chart on the starting system?

Are you able to jump-start the car with another battery (car)?

Okay recap of what i did:

Battery voltage is 12.6
disconnected battery and reconnect check terminals
jump the clutch safety switch with a paper clip
check fuse 42 40amp ign fuse under the hood with a test light both side lite up so has power?
fuse 21 ignition signal 7.5amp fuse no power with new and old fuses
swap the relays 2 and 4 under the dash

no aftermarket alarm
dash light come on everything still works fine
able to kick start
original starter

any suggestion would be greatly appreciated and anyone know why i am not getting power to starter signal fuse 21?

Understand you can start the car by pushing it and then engaging the clutch? If so it's the starter circuit.

You should be able to "jump" the Start button (but I've no clue how to get there!).

My shop manual is three hours away but I can check tonight if I'm back at a reasonable time.

Battery ground okay I really think its a connection problem before or after the starter cut relay I just double check I have no power at clutch safety switch and at the fuse 21 starter signal. possible the starter switch

From wiring diagram, looks like possible starter cut relay or ECM issue.
