I go to start the car I push the clutch in, and it's still acts like the clutch is not pushed in to start it all the power comes in on the ignition, but it doesn't come in I bypass the clutch safety switch and it still does the same.
I've checked my gauge fuses and all my other fuses are related but I don't know where the relay is
My connections and battery everything is fine because the power comes on to my car everything working great when I push the clutch in it just doesn't want to engage to the starter.

Hello,

I would suggest checking if you are getting 12V at the starter motor when cranking.
This is at the purple wire at the starter solenoid. See image 2.
If you get 12V at starter solenoid next check that you are getting 12V at the thick red wire at the starter. If yes, then this could point to a possible faulty starter.

If you do not get 12V at the starter solenoid next please check that you get 12V out at the ignition switch, yellow wire. see image below.

If ignition is outputting 12V at yellow wire next check the integrity of the wire to the clutch start switch, then the purple wire to the starter solenoid. See image 2.
