No trigger signal from ECU?

The vehicle listed above is a Sylphy G10I model. I recently changed the ignition driver chip on my ECU because it does not send trigger signal to cylinder 1. There was no voltage recorded (O-volts while others were 0.1volts and working fine).
After changing, cylinder 1 has signal from the ECU (0.1volts with the others) but it does not trigger higher voltage (1-5 volts) to the ignition coil when I start and run the engine. All other cylinders are working fine as normal.
