My standard first question: Do you get the same results on A & B controller? If yes, it is very unlikely that both controllers have same problem so start looking for a wiring error. Possibilities include backwards connections on the crank angle sensors. If you have an analog volt meter, connect it across a sensor & see if the meter deflects positive as you bring a piece of steel or iron in contact with face of sensors. The return line should be on the negative voltmeter lead when it does. Use the lowest volt range. If it deflects negative, you've got it backwards.
The other possibilities are (almost) endless. Check everything.

Subject: [FlyRotary] EC2 - No spark problem
Hi guys,
I'm at the point where I'm trying to start my (3rd gen turbo LS1 coils) engine for the first time.
I turned the engine for about a minute. It made no attempt to fire at all, so I removed a plug, grounded the side against the block and looked for a spark while cranking. Nothing. I checked the hot pin on the LS1 coil, and it had 12v. The other 3 pins seemed to be grounded. Other than rechecking ALL the EC2 connections I'm not sure where to go from here. Is it possible that my crank angle sensors aren't putting out the correct pulse? How can I test this? Can I test whether the coils are getting a firing pulse? If so, How?
Any suggestions welcome.
