Had the exact same problem in an 88 Saab. Both Saab and 240sx use a similar clutch disk system, so check it out.
If you're havin' to push your foot to the floor to get your clutch to engage and allow shifting, it isn't your clutch. A toasted clutch does jack 'n crap while you stand on the gas, in any gear. However a spongy pedal that does allow shifting is leaky cylinder / low fluids like getheflow suggested.
If there's a leak in fluids somewhere, there's not gonna be much pressure in the lines. AND, every time you release your foot from the clutch pedal, that same leak that's letting fluid out is gonna be suckin' air in. With little to no pressure in your clutch lines there's no way the throwout bearing can depress the pressure plate and engage/disengage your clutch.
When I had this problem I ignored the leak, kept topping off the reservoir, and learned the hard way that it was a dumbass idea. It cost me a transmission. Crushing your car into gear is horrible for a transmission, and one with over 150k miles on it is going to lay down and die under that kind of abuse. Get the leak fixed ASAP. Find it yourself or pay a mechanic to diagnose the clutch lines -- you'll save a ton of cash, trust me.
