So builds getting kinda close. After installing clutch master & slave cylinders to metal units, replacing the line to stainless. I was going to try and prime the motor b4 starting. But issue, when I depress the pedal it does not seem to be recognizing the pedal being pressed therefore not turning engine over.

I have ECU, fuel pump fuses removed for priming but it won't turn over. In pic below please verify which switch I should replace.

The blue one is what I think has crapped out. It's a tricky part to re install.
