ASV 1.9 TDI won't start after fuel pump replacement

Hello everyone,
I'm feeling stuck today and can't seem to make any progress.

Skoda Octavia 1.9 TDI engine code ASV with VP37.
I installed a new fuel injection pump, disconnected the camshaft, set the crankshaft to top dead center (TDC) in the timing hole, and disconnected the electronic spark advance (ESA).
The pump is partially bled, and fuel is spraying out well from the loose connections.
I have set the starting feed rate to 0.70mm, but nothing is happening.
If the pump is connected and everything is set to "OT" (Top Dead Center), shouldn't the start of injection for the FIRST cylinder be readable?
When removing the pump, it was strangely rotated 180 degrees, so that the position for disconnecting it was directly opposite on the shaft.
Right now, I'm starting to doubt myself and wonder if the pump is installed 180 degrees out of alignment.
The ruler only fits in one position, and I haven't been able to find any other markings on the rotating arm.
Does anyone have any suggestions?
Regards,

Edit:
I rotated the pump 180 degrees, and now it's working. I don't understand the purpose of the offset position in the pump.

Hi,

The thing about the stake positions is correct as is.

Since the camshaft and fuel injection pump complete one revolution for every two revolutions of the crankshaft, you would have simply needed to rotate the crankshaft one more revolution past the top dead center (TDC) position. Then all the alignment points would have matched.

Best regards, Rainer.

Oh dear, you're right, and I must have been dreaming. Thank you .

Edit: I didn't even try again because I assumed the Northwest-aligned ruler only fits in one position.
The groove is centered, unlike the 1Z model, which has an eccentric groove.

Thank you .

Okay. It also works when rotated 180°.

Interestingly, the engine still starts even when the pump is rotated 180 degrees. It is then injected after the exhaust stroke, fresh air is drawn in, and the mist ignites as soon as the ignition temperature is reached, which usually happens well before top dead center (TDC), and consequently, it knocks.
Therefore, I would look for the error elsewhere.
When properly adjusted, meaning rotated another 180 degrees, it still
