My father is bringing a new coil tomorrow to see if that might be the problem. Is there anything else I should be looking for? This is way different than my 85 Carrera but I want to learn about the 944. The car looks great, I just wish I could get it to start so I will have a good base to work with.

1. Does the tach bounce 1/16th of an inch when you crank the engine?
2. Did you get a spare DME relay to try? Clarks garage has a "jumper" to make if not.

Why will it not start?
The usual answer is that the Motronic DME computer is fried. Someone in the last 5 years tried to start the car and with a dead battery used a friends car or battery pack and "jumped" the battery and ruined the computer.

The computer is a 944 618 121 04 and not that expensive to get used. Usually $150 +-.
