No Spark But Power At Coil

[dav1 7]

My mate is putting an omex system in his car. He's bought the loom converted. He's got power to the coil but when he turns it over there's no spark? Any help please.

Is there still power to the ecu under cranking? Should have one main live for the ecu, red wire, and two earths both black.

if its got power, check the crank sensor wiring, if it doesn't know its turning over the engine won't try to fire. Do you have the comms lead so you can connect the ecu to a laptop....check all the parameters and settings are correct.
