I have a 1989 GTUs, and I'm now having some starting issues.
Sometimes it'll crank over but when it does, it's very slow and seems to have issues fully starting.
Other times and this is most prominent, when I go to start it, it won't even turn. All I hear when I turn the ignition with the clutch all the way down is a click but it's coming from the clutch pedal area. It used to need a jump to start, now it's like it's dead. I just replaced the battery and spark plugs.
Any ideas?

 

look up clutch interlock switch( clutch safety switch)

 

check to see if clutch has stuck to plate or maybe something around flywheel

 

I would also check the starter solenoid. Sometimes they can get stuck and just click.
