Maybe something with the safety switch on the clutch, or the wiring going to the starter. May be ignition switch also.
there is a safety switch on the clutch, it should be on the inside of the car that the pedal has to activate so the car will start, apparently that switch is bad.
There is a switch mounted under the dash above the clutch arm. It has either slipped out of its bracket or is bad. It is there to keep you from starting the car with the clutch engaged. A safety factor.
I think it has a hydraulic clutch and no adjustment.
Suzuki Sidekick has a cable for the clutch. No fluid required. If it hard to push or seems to 'stick' then replace the cable.
Not with the clutch by itself.
It prevents engine cranking unless the clutch pedal is pressed.
many posts for this here. top of clutch pedal. at pivot.
the clutch pedal
if I understand the question you asked correctly, I would say you are in need of a clutch but it might need adjustment but not likely.
The compressor clutch does not need to be shimmed. The outside disc is pressed on until the proper air gap is achieved. If it is pressed on to far it has to be pulled off and reinstalled.
its a cable. only 96-98 SPORTS 1.8 Liter have hydr. clutch. (of the early models you mention)
To install the clutch cable on a 1995 Suzuki Sidekick JX 16 valve, start by disconnecting the old cable from the clutch pedal and the transmission. Route the new cable through the firewall and secure it to the clutch pedal assembly. Next, attach the cable to the clutch release lever on the transmission, ensuring it is properly adjusted for tension. Finally, check the clutch operation to ensure it engages and disengages smoothly.
