Hello
Anyone has situation with Renault Master 2.3dci biturbo 2017 year where the car not crank and fuel pump not working? All fuses check, I change ecu sid309, uch, usm and dash (all starter kit) but is the same. I have no error exept intake air pressure sensor and p0033 bypass turbo valve. Fuel pump working when I connect to 12v? As the same is starter motor. Maybe any suggestion?

You have checked fuses.. but what about relays?
If relay cannot switch and energize circuit, it does not really matter that all fuses are ok.

But I change all relays too

Wiring damage, probably.
Need to open wiring diagrams and check that there is voltage on every module and equipment piece that is related to starting the engine.

First clue might be your intake pressure sensor - it may not receive a +5/+12V reference signal.
There may be many other various things on the same power loop which result in your no-start condition.

Please check that there is power everywhere where it needs to be. If you are not familiar with this work - find yourself a knowledgeable electrician.
