1995 saturn will crank but wont start it is a manual transmission and wont start by popping clutch either

Try adding water absorb ant fluidd, ie heat. To fuel. May have condensed water in tank. Popped a fuse or breaker

Sounds like the friction surface of the clutch disc is slipping. You would have to install a new clutch (clutch disc, pressure plate, and clutch release bearing), and have the flywheel surface cut and polished back to perfect smooth by a shop.
Manual transmission gears don't slip like automatics. And lack of fluid in the transaxle or the hydraulic clutch system won't cause this either.

Something is broken, that is for sure, pull the transmission out and first look at the clutch plate.

Sounds like you might of broken the pressure / clutch plate. Are you able to hear the starter turn and engaging the solenoid ?

hello there
eventhough you are in Porsche forum i think you have a problem with your starter i would replace it

Check also your connection on starter

sounds like your washers/bearings/spacers finally degraded. To make sure, pop off the little flexy cover. You will see a linkage that goes straight into the transmission. If the bearings there (the little white plastic ones) look eaten up, that's most likely your problem.

Unbolt the the two nuts that hold it onto the transmission. Then grab the slave cylinder and turn it counter clockwise and it should pop out. That is correct because holding it in the hole and turning it clockwise seats it back into the transmission.

Remember to remove the connection between the clutch pedal and the master cylinder or put a brick or something to hold the clutch pedal up or else removing the slave cylinder without the above note will ruin the hydraulics and allow air to get into this airless system.

you can reach down and turn the crankshaft pully by hand to see. If you have a manual transmission, it's even easier; push it a little, put it in 3rd gear, and pop the clutch, and see if the engine turns that way.

If it's an automatic transmission "make sure" it's in park or neutral. If so possibly a bad neutral safety switch. If a Manual transmission just get a bunch of friends to push you and pop the clutch in 1st or 2nd gear....and away you go. Make sure you turn the key when popping the clutch.

This vehicle has a pair of shift cables which attatches to the shifter and runs to the transmission shift housing.To diagnose,removal of the center console is in order so you can inspect and verify the shifter/cable connections and movement,then verify the cables move the linkages properly at the transmission . These cables are a fairly common failed part and sold as the set,these are a dealer item and no aftermarket cables are available .
