Daewoo ecu not responding

[Nqkaf]

Hello, the car is Daewoo Tacuma 1.6 dohc 2004 year
After working on the cylinder head, now the car cranks but doesnt start.
There is no spark, and diagnosis doesnt connect to the engine ecu.I can connect to airbag or abs.
When i move the crank sensor past a metal, the fuel pump activates, so something is counting the rpm.
Everything is rechecked a lot of times, ive connected another ecu(without learning immo) just to try to connect but it doesnt respond again.
I cant find any wiring diagrams for this model, does anyone have any experience with these?

First check your ground wires, and fuses ...

They are chechek, the ecu has 12v and 5v on some pins but for this car i cant find any pinout to see what is for what.

After days of measuring, thinking, checking and cranking, i was just about to go home and reached to disconnect my obd. While wiggling it i heard a click and now car starts without a problem.
