What would cause a manual transmission car to lose clutch control and also simultaneosly not start now?

While driving on the highway, the car seemingly drops its transmission/clutch. It could not get into any gear, but instead just revved up with the gas pressed. I thought my clutch just went. I pull over and turn the car off. I tried to start it and all I get is a whirring crank. It tries to turn over but is having problems cranking. It doesnt seem likely that the clutch went at the same time there was an engine problem. What could this be?? My best guess is the flywheel, but I am an amateur and want to diagnose ths before ripping the whole car apart to find the problem.What would cause a manual transmission car to lose clutch control and also simultaneosly not start now?
badly worn clutch (driven plate) or partially disengaged due to pedal sticking and dodgy starter solenoid.





One problem could've led to the other. if the clutch was slipping on the highway excess heat could have built up in the bell housing causing the starter solenoid to bind/fail.





After the clutch ';failed'; was the engine propelling the vehicle at all?





If it wasn't then the flywheel bolts have either worked loose or sheared.





In any case the gearbox needs to be removed to inspect the fault.What would cause a manual transmission car to lose clutch control and also simultaneosly not start now?
sounds like seperate problems. However pull your inspection cover for the clutch and or the start. Look to see if you still have teeth on the flywheel. That should help with finding out about the starting problem. Either the gear teeth are gone or the starter bendix is not fully engaging the flywheel.





How much free play in the clutch pedal?Is it a hydralic clutch? How old is the clutch? perhaps the springs in the pressure plate let go. Just some thing to check out. Good luck.
Maybe your gear synchroniser was defective. The synchroniser cone is a wear %26amp; tear part. You will have to send your gearbox to a transmission specialist for overhauling.
