The car wont just start.

Before dismantling the engine it worked fine.

The story.
I decided to replace head gasket for the car because of leaking valve seals.
I had a spare and controlled head gasket so decided why not to try.

Now I'm here.

The diagnostics gave me some of the errors:

1: ECM-0003 Fuel volume control valve. Signal too low
2: ECM-0118 Engine coolant temperature (ECT) sensor. Signal too high (probably caused because I did not fill coolant into system yet)
3: Something related Software faulty signal as well, but it was previously as well because DPF was witten off and it worked previously with this error.

The communiaction values:
RPM sensor: gave 300-400 RPMish
Fuel pressure sensor: If cranked, reached up to 40k hPa.

Is there I'm missing?

The cams were intalled as per manual:

Edit: The car runs for split second with Easy-Start

how long was the battery off ? these can have in rare cases a loss of ECU security info with no battery power for a few days , so a ECU software reload needed at the dealer if this is the case ,

It was without a battery at least a month.have been reading about this previously as well.

Update: it’s up and running. Thank you all.

The problem.

The error codes I had initially. (Coolant sensor and fuel control valve.)
It seems I have connected the wires to them wrong. Fuel control valve to coolant sensor and vice-Versa. Probably that is why it did not start at all. And of course had to prime the fuel as well. Special thanks to Simmy as well.

Thank you all.
