Make sure you have the correct coil / igniter combo.

The late coils had an inbuilt igniter but earlier ones did not.

To check measure the resistance between the power and signal wire. If its low around 1ohm then you need an external igniter.

Also check the voltage to the coils. If this is not 10 or more volts you will have a weak spark.

it have a built in igniter when i test the ignition from the ignition test it work fine but when i start the engine it don't work .. i think it may be at the trigger setup but the rpm read right values and at run-time values window ( trig. 1 & trig. 2 & sync ) is ok and there is no fault
