So last night I came home and parked my car in the driveway, everything was working fine. This morning I go to start my car and it won't crank at all. All the lights come on but when I turn the key to start it, nothing. I checked the starter fuse and its fine, I'm not sure about the starter relay so I'm going to replace it. I'm also thinking it might be the clutch interlock switch.

I know there is a bunch of stuff that can cause this but what are some other things I can look for?

Its a 93 4WS

Thanks guys
