Eduardo,
I'm glad the problems from your other posts are fixed enough so the 944 got you somewhere.
If you checked for spark on the sparkplug wire, the rotor button inside the distributor cap could be bad. Some of these have what looks like black epoxy with some kind of electronic component. If there is a little hole, it is probably blowed. You can check the rotor with an ohm meter. I think they should check between 1 and 1.5 K ohms. If it is open it is bad.
If you checked for spark at the coil, it may be the Motronic computer no working. If you have a noid light, you can check the injector firing to see if this is it. If the Motronic is not firing anything it may not be getting power through the fuel pump relay. In your car, early 944, I think this is the 2nd relay from the door on the top. This sends power to the Motronic terminals 18 and 35. The Motronic or DME is under the dash on the driver's side. You should have battery voltage between either one of these terminals and ground with the switch on. The 944 relay has been superceded at the dealers with one with a 996 number.
If the injectors were firing, you can put a volt meter accross the two coil terminals while cranking. If the voltage is changing then it is probably a bad coil. If nothing, it points to the Motronic. Check that white 9 pin plug by the fire wall to make sure thre is a good connection on the green wire that goes to the coil.
If it is good, it might be one of the two sensors on the back of the motor that pick up off the flywheel. There have been recent posts on these.
I check them by ohming them and hooking them up, cranking, and see if I,m getting a small AC voltage. I have an old good one to replace one in doubt. Yours are probably set the right distance off the flywheel if it ran before quitting.
That green wire off the coil also connects to the tach and alarm, if you have one. Could be aproblem there.
I,ve been whipped by this so I'm in the process of putting a TEC II on a 944 I'm fixing up for my daughter.
Pelican has the wiring diagram for an 84 944 on their web site.
Good luck,
