If you want to read the faults from the connector you must use a pulse counter, you can do it with 2 diodes, 2 resistors, a switch and 3 cables., that module did not reach 20 possible errors. Look for the electrical schematic and check the components it had such as the temperature sensor, idle switch, inductive position sensor...it is a very simple system.

I have checked the + and the - at the ELZ, that is good, I have also checked the engine speed sensor at the plug that is also good but Im getting no spark or coil control 

SD Connect C4 is working ok ? 

I had case that "+" power was not present in socket. Only ground was there. 

Need to add it from battery directly, the best both.

I think, K-line cable I have used. Not sure about KL15 - maybe was connected too.

PS.
Not sure that all modules was answering.

Yes I connected direct to battery for power as no + in the 16 pin plug 

Such EZL is not-diagnoseable.

Thanks for the info
