1983 Porsche 944: Starts, won't stay running

Ok, I have read the forum on every thing to do with a car not starting. Here is what I know:

First the symptoms:
The car starts for a second or two then stops. I have squirted carb cleaner into the intake and once or twice I was able to accelerate it up to 6K RPMs before quickly dying.
So: obviously there is spark and fuel. Is there enough fuel?

How I got here:
Bought a car that didn't run. Put in 3 DMEs and the third one was the charm. A switch was put in to force the fuel pump on (new fuel pump) and a switch to force the DME on. That was good enough to get it home. Clutch died on the way home (Tulsa to Atlanta).

Just replaced the clutch and took it for a ride. Felt like the brakes were on, and the rears were. Rebuilt the rear brakes and it now rolls nice, but the car won't start. I took out the switches and fixed the wiring to the DME/FP relay. The fuel pump turns on when the computer is trying to start the car. There is spark, so relay is working nicely.

I tweaked the position of the speed sensor so that I
have 4.5 V pk-pk.

Still no difference in the car's ability to stay running.

Wit's end!!!
