HELP-nissan s15 G4 install no spark when cranking but spark when tested

Just finishing up an install on a s15 and am not able to get it to start! When I test the ignition with the test function the coils work just fine-hook up a timing light to them and it blinks along. BUT when I go to crank the car the timing light wont blink!? The trig one/tri2 ECCS has been synced and seem to be working. But when cranking it takes a long time for the triggers to sync to YES and I am getting no engine speed/RPM signals......when I do the RPMS bounce around from 40rpm to 400 rpm??? anyone have any ideas?

Hi Mike, 

Some possible things to check:

Do you have ECU hold power enabled?

Do you have anti-theft enabled?

What is your ECCS widest slot number in trigger setup?

If you turn Ignition to off do you get a reliable RPM reading?
