G424E Engine. Ran thru manual several times to see if Im over looking anything, seems to be a rather easy and straight foreward engine.

No Codes.
CEL on after key on, according to G424E manual it should turn off.
New ECM
New Smart Coil
New Crank Sensor
No Spark out of smart coil.
Verified my 12v and grounds. Only thing I do not know is im not sure what signal I should see on the Coil Driver wire from the ECM at the igntion coil 5v or 12v and pulsed or constant?

Checked wiring between crank sensor and ECM. OK
Checked wiring between ECM and coil. OK
12v at coil good, grounds good. No blown fuses. Relays seem to test good.

I have 3 questions
1. What signal I should see on the Coil Driver wire from the ECM at the igntion coil, 5v or 12v and is it pulsed or constant?
2. What is the XDCR? Were does it come from and how does it play into this system? Seems to be a 5v transducer of some sort.
3. What else in this system could be preventing this from starting.

Dont ask about a laptop cause one one here is a dealer nor would have one. Small island...
