Hello everybody
I have a dell latitude 5330 which does not turn on (except the power button and the keyboard backlighting for a second, no fan ..), I have the primary voltages 3.3v and 5v, the 13v from the battery, no processor voltage and no gfx voltage, and I have the 1.8v present I don't know what it is for (maybe the ram), if anyone has an idea what it could be?
nb: I flashed the bios and it's the same result

It is a Dell so adapter ID matters. Search the forum for the many discussions on PS_ID. This single line must not be defective.

Can anyone help me find the PS ID without a schematic?
and does PS ID exist even for Dells that only have Type C ports?

No PS_ID on the Type C models. Would you have a USB C meter? If yes, place this between the external power adapter and your Type C connector on the laptop to intercept the power delivery contract being selected by the laptop. In the end, the host logic board will extract the multiple power delivery contracts from the external power adapter -> then select the most suitable voltage / current power delivery contract to power the board. If you are stuck @ 5 volts (default) then the USB Type C PD controller is not performing the job to power the board. Often, the power delivery contract should be ~20 volts. Be sure that you are using the official power adapter or at least exceeding the requirements for the power (ie. 100W USB Type C adapter should be fine - regardless of brand as long as it is true to the power rating markings).
