First, welcome to the forum
!
Second, you will need to do a little basic reading about your CIS fuel injection system. I suggest you do a quick reading on the following site:
CIS Primer for the Porsche 911.
To get you going however (no pun intended), you can try the following technique. Since it sounds like your car is not getting fuel and it has been sitting for four years, try to pressurize the system first. To do this, remove the air filter from the engine and you will see a metal "plunger" inside the intake. Turn on the ignition, go to the engine compartment and gently push up on the plunger. Doing so should cause the fuel pump to run and pressurize the fuel system. Hold the plunger up until you hear a "squeal" from the injectors--that's the sound of fuel being sprayed into the intake ports. As soon as you hear the squeal, let go of the plunger as you could flood the car, or worse. Now, the system is pressurized and fuel is reaching the cylinders. Try to start the car and report what happens.
The gauge set referred to is a pressure gauge with a "T" connector and valve that is used to diagnose CIS systems. You
will need one.
In short, there are many reasons for your situation, but since the car fires with an injection of fluid, it does have spark and compression. Try the above test and report back what happens, and read the Primer.
