Check cam-belt/chain timing.

These have no keyway on the bottom pulley iirc ;) put scope one on both crank and cam sensor and watch.

you have a secure system to avoid mistakes?

sorry for my bad english

You must adjust marks on belt and pump. You have two marks on belt for pump.
Pump for it self do not need timing , but cps make reading from pump puley.
And , look for parameters with diag, there is syncronisation, it must bee "Yes" on idle and "no" when eng not running.

Hi

Have checked the wiring from sensor to ECU ? Also remove the Multi Plug on ECU Unit and clean it.

Also press the pins in the sensor plug it could be clips are lose and not connecting properly to the sensor pins.
