1996 Daewoo Cielo ignition

The engine was overhauled changing half engine but after assembled its cranking but won't start. I found out there's no electrical current in the spark plug high tension wire. I change the whole distributor assy. and the ignition coil is new and both the connectors was tested and it is good but it failed to spark.

I think this model the sensor is in the camshaft inside the distributor assy. And it was already changed, but still no ignition spark.

Is the ECU has something to do with this? please I badly need help.

Thanks ,

Armando
