No Start Porsche 924s 1987

Hi I own a Porsche 924s 1987 that's automatic. I have done quite a bit of work on it replaced all the sensors on the engine block including speed and reference sensors and gapped the spacing between them and the fly wheel. I have sent the DME in and got it refurbished. I also replaced the engine and the exterior wiring harness that goes to the lights and signal lights etc. However my car cranks and will turn over if I spray starting fluid into the car but will not continue to keep running. I checked injectors with noid light and I'm getting no signal. I have 12V on both sides of injectors which is normal because the DME grounds one side to complete the circuit. The speed and reference sensors are good. Any help would be appreciated. Thanks Alex

Sounds like the DME ECM is bad. Who "refurbished" the unit? Make sure that the injector wires aren't shorted together.
Manually ground one side of the injectors (pins 14/15 of DME) and see if the noid light flashes with key on.
