87 944s: clutch doesn't disengage:

1. when I crank the engine with clutch pedal depresed, shifter in 1st gear, car lurches forward;

Possibly the slave or master cylinder, or air in system, or is the clutch broken? Pins in the shifter likage maybe?

Where do I start?

The car has been sitting several months since driven last;
