CIS is a general form of FI........included in this group are; K-Jetronic, K-Jetronic with lambda and KE-Jetronic. If you have a warm up regulator, than yours is one of the first two.

Yes, both the cold start, and the injectors get their fuel from the fuel distributor (FD)......both share the same fuel pressure. But, their operation is different. The cold start system is electrically triggered on and off. The fuel going to the injectors is run strictly by hydraulic pressure, and mechanical activation by the plunger, which is pushed by the sensor plate.

Plungers don't just fall out, even if the unit is upside down.......at least they shouldn't.

Try this: remove the air filter.......this exposed the sensor plate......there are two kinds; one where the sensor plate functions upward (you will need a magnet), and the other, where the plate funtions in a downward direction. Run the fuel pump and lift, or push, on the sensor plate.......you should get fuel to the injectors.

If not, then you will have to check the plunger. To see it, one has to remove the FD from it's base. It is held in with 3 srews, and lifts right off. The plunger in on the bottom, in the center. Be careful.......while most plungers will remain, in some early systems, the plunger could fall out.
