CRX: ZC not starting

[Vargasgodoy, Andres AK3 (HS-14)]

After installing a new clutch and flywheel my engine did not start, the ECU is flashing 8 times, but the car starts and runs perfectly if it is pushed started, timing is set properly, somebody told me to replace the starter relay that is underneath the dash, did it but still not starting, any ideas?
