I've done my research but can't find anything occurrig to my symptoms so here's what's going...

I'm driving my Z down the street in 1st gear when all of a sudden it stops accelerating, i put it in nuetral then back into 1st and still won't accelerate. I park and turn the car off and start it in 1st gear without the clutch pedal in and still won't move. I got it towed back to my house and since then has been parked. While parked i try starting the car in all gears and still won't move. Throwout bearing isn't making any noise, no grinding of the clutch, clutch pedal and gears move smooth like nothing happened. I'm going crazy not knowing what the issue might be an need help asap please!
