Is that the low pressure fuel pressure sensor? If so, is it not in the injection (high pressure) pump (monitoring its input)?

Yup low pressure fuel sensor. And i think you mentioned fuel rail sensor. Or these are the same thing just with different names? Cuz now i have engine code p1180. Fuel filter changed, fuel pressure regulator (near hp fuel pump) is working and seals changed, lp pump (oem i think, near fuel filter) also working while ignition on, engine starts easy but pass 3k revs i get code, warning light and limp mode. When i realese gass pedal warning light gone. And everyting starts from the begining.

You need to drive it while a diagnostic device is monitoring the rail values, so you can see what's going on. If the LP rail sensor is faulty, the engine won't start. If the HP sensor is giving incorrect readings, the engine can start and run quite well, but can also give a variety of odd faults, like you have, so you really need to look at the live data.

I tried to measure voltage of HP sensor. I get 0.5V ignition on, 1.3 while idle and 2.3V at +/- 3k revs so i think its good according to the data sheet.
