When you replaced the ECM, did you do the security reprogram? The Engine ECU & theft alarm ECU have to be synched up or the ECU will not let the car start.

Any other work done recently? Maybe something that could have bent the trigger on the flex plate?

Flex plate? No recent work done to it. It stems from when I went out wheeling and got "delayed". I had a constant drain on the battery (12v to <5v in 30 min), I got that fixed..now this.

Check the wires at the crank sensor. Right near the connector there is some electrical tape wrapping the two wires together which is likely hiding some exposed wires.

You can just unplug the sensor and pull the wiring up to the engine bay. If you pull back the heat shielding there is electrical tape wrapped around the wires right at the connector. They will almost certainly have no insulation left on them. That might not be your issue, but its simple to check and repair.
