Confirm you are getting 12V at the TEC main plug connector.
Next I would try a different crank sensor.

Here is my experience with last of three TEC3r's I have repaired/tuned.
Bought a race car with that system. Went to pick it up, wouldn't start. Owner said it started an hour earlier. Was getting power to the ECU, sent to Electromotive for repair. They claimed to replace a capacitor. Worked intermittent after. Replaced crank sensor using Richard's hall unit. Tuned car.

Worked great for a year.

Same issue a year later but smelled burnt electrical from the unit. power to unit, but intermittent green light. Sent to Electromotive, they couldn't find anything wrong. Says works perfect on the bench for weeks. Told me to try a new crank sensor.

In the mean time customer couldn't wait. Switched to AEM, never looked back.

As mentioned above, Support is everything for EFI. Richard Clewitt is very good with these. I wonder if the new Electromotive GT series is much improved? I must say, once tuned the TEC3r ran quite well.
