No Start Question

I have a no start condition and it appears the ECU won't send a relay release signal to the starter lock relay. So.. the question is what sensors/conditions will keep the ECU from letting the engine start?

I bypassed the fuel pump relay and I can hear the pump running. I inject 12V on the starter side of the starter lock relay and it will crank but not fire. When I do that, the tach shows ~500 rpm so I 'think' the crankshaft sensor is working.

Any help is appreciated!

Either the clutch safety or the security system.

I've bypassed the clutch safety switch and just replaced the immobilizer, which was reprogrammed to the ECU and key. All the normal security stuff works otherwise.. windows, doors locking, etc.
