Did you re-check the whole track of pipings, and diag' the car since ?

Might be a defect ?

Hi,

You have changed the high-pressure pumps in Stage 4, right?
It would be obvious that there is a defect here?

Or an assembly error?

Check the wiring, connector and the pressure sensor bank 1 (on the right, in the direction of travel)
Or swap left to right and check if the error moves.

Kind regards.

I had a fuel pressure drop and after a LOT of diagnosis, it was a bad ECU.

Once the ECU was replaced and coded to the VIN, all was fine!

We changed the injectors
sensor changer

if you drive without accelerating no problem but when you accelerate the car to the fullest this puts you in safety apart from a lack of pressure on rail A due to the pump even when lowering the pressure

only one pump is faulty

apart from spool where I can find hp pumps?
