Beyond confused, change clutch master n slave, now no start. Hear click behind dash. Check clutch safety switch, even took it apart to confirm how it works. Pedal up makes connection, pedal down breaks it. Started fine yesterday.

With all tight knuckle spots that is involved with the job I would Check all the plugs and wires in the area, the plugs on the Ignition switch, the Vats and so on.
Did you Disconnect the Battery while doing the job, Because a Loose Battery Connection can be the problem to.
You may want to get under the car and see if the Starter request is getting down to the starter Solenoid.

Being you have a manual and you've messed with the clutch master cylinder, got a nickel that says the switch on the clutch pedal is either out of adjustment or got broken during the change-out.

Look up on the clutch pedal way up on the pivot for a switch. Temporarily disconnect the wiring harness from it and jumper it. Now try starting the car - bet it works. If it does, check the FSM on setting up the adjustment on it correctly if the switch checks out ok. If not, I've not found a replacement so you may have to leave it jumpered.

Let us know what you find. Good luck.

PS there's a switch about half way up the clutch pedal, that's the wrong one. That ones for disengaging the cruise control. The one at the top is the one that when you depress the clutch pedal is one of the components for energizing the starter.

Ok i see now well can't see that is. Can't force my body in enough to see the top one. Im just seeing the cruise switch. So seat removal is in order grrrr. Worst part is last week after the two days of trying i pulled or strained something where my right arm wouldn't move with serious pain. Why now im just getting back to it....

Been there, wrote the book. Took me a couple of weeks to figure it out and get it jumpered. You have no idea how many times I came back to the wrong switch (the cruise control one), that's why I made specific reference to the correct one.

You could try a light, a mirror and a little luck and see it from the bottom without taking out the seat. Just pull the connector off the switch and make up a little jumper, plug it into the connector and try starting the car.

Good luck.

Even just searching for the word switch. I get 12 pages of stuff, clutch is not listed. Its a barrel switch with linkage rod, no adjustment. Must be bad.

That's the switch but the 84-86 has a different setup so that one won't work in my case. I just left it jumpered, being I'm the only one driving it I know about it. When I take it into the garage I have a note I post on the dash that the switch is bypassed.

No big deal, I grew up without a clutch switch in the vehicles, so I deal with it that way.

This is wrong. Pedal down completes the connection so the car will start. Pedal up breaks the connection. Car will not start.

See post 4, basically everyone finds the cruise switch. The real one is burried deep up high out of sight n reach. Big aluminum brace blocks easily seeing it
