Hello, I have a problem, after starting the car, a check engine light appears with the error: 4620. After removing the error, it disappears and does not appear until I turn off the car and start it. I tried to bleed the ISTA fuel system and the car suddenly turns off with a check engine light and errors: 4620 42E2. Any idea?

Report here the rail pressure values during start.
Did the car run fine until now?
Does the fuel pump run when ingition on?

I replaced the fuel regulator/valve in the rail at the end and the fuel filter because I had a problem when I accelerated, the car would flash the check engine light, now it's better, it doesn't pop up anymore, but I get the check engine light every time I start it. this is how the fuel pump works after ignition and you can hear it. when starting the car the current value is 1600
