Skoda Fabia 1.4 16V not start

[SebaGTC]

Hi.
It came to me Skoda fabia 2005 1.4 16V engine code BKY. The car was at the mechanic's, did not walk on 1 cylinder . They replaced candles and coils. The car has a gas installation. Compression checked - OK. After this operation, the car stopped starting. Crankshaft and camshaft sensor replacement, still unchanged. I checked the sensors installation and it's fine. The ECU has all the power and ground. I replaced the ecu, nothing helped. I tried immo off but no changes. VCDS sees the engine speed, but the ecu does not expose the impulse to the coils or to the injectors.
I also replaced the electric module and the throttle, but it also did not help. there are no errors in the car. All controls behave normally.The whole car installation is checked and looks good Has anyone encountered such a problem and is there anything to help?

Gas installation may be the problem. Check the wires and disconnect it from installation. See if it starts.

I disconnected the gas installation, connected the wires, and then the same.

Coil and injector supply checked? it goes from system relay

Yes. Checked. I have power after the fuel pump relay, both for injectors and for coils. Checked masses. I have everything according to the scheme from WOW.

can disconnect all cubes from injectors and coils, and then check the impulse?
what production shaft sensor ?

[SebaGTC]

Yes. I unhooked them all and checked one by one. Original sensors BOSCH.

What dtcs does the ecu throw? Does the car start with starting spray? I assume not, once the sparks have no signal.
Did you checked the egr if it has, not to be in open position? What about distribution signs? Are the axles aligned?
Ecu is marelli? If you have offed it, did you try starting the car with ipcs disconnected?

wrote that there is no dtc, maybe wrong timing? but if it cuts off the spark I do not remember

Problem solved. When replacing the ecu, I made an EEPROM clone. The EEPROM was just broken. After uploading the bin from the new ecu to the original one and adding it to the car, everything works. Now I have 2 ecu working. I have no idea why it broke. Perhaps the voltage dropped during the compression measurement or the battery is damaged. Thanks to everyone for any suggestions.
