clutch pedal switch problems
over the last year or so i've had to push the clutch pedal harder and harder to engage the clutch pedal switch so i can start my truck. now i have to push as hard as i can on the clutch to engage the switch. is there any way i can fix this?? i've tried messing with the switch. it seems that it moves freely on the master cylinder push rod. if i push it all the way forward (towards the firewall) it has a springyness to it. it has about an inch and a half of free play. i have no idea how this thing is supposed to work. is it supposed to have a home position? is there something that gets tweaked on these cluch pedal assemblies? surely the switch isn't bad.

On my 88 f350 I found the bracket/arm which the arm/rod to the master cylinder was worn, I replaced the flat bracket/arm and got a new nylon bushing which holds it tightly on the pin and the extra free play went away, my switch is bypassed, not one the wiser moves by the prior owner and I am just too lazy to hook it back up, but it is only me driving it. Look underneath above your gas pedal for loose parts in the pedal assembly.
good luck

Definitely check the pedal shaft bushings as lostinfords suggested. It seems pretty common for the master cylinder push rod bushing to pop off the cross-shaft lever arm, which prevents the clutch from getting the full stroke.

Mine did this, brand new everything. I got tired of having to mess with the clutch to start the truck, but didn't want to disconnect it. What I did was use a small hose clamp and put it on the shaft before the switch, kinda making it think the clutch is pushed in further than it is. It works, and my truck starts every time now. I know it's not the "right" way but it works better than reaching under there so the truck will start.
