Hello The van in the above title stalled and never started again. I measured no pressure, flow coming from the high pressure pump to the injectors. So I replaced the pump with a new one. I have no error codes. So I backprobed the pressure regulating valve of the new pump on both wires on the van. In...

Sorry I did not read carefully. It comes fuel on the return line of the pump but it does not come from the high pressure side of the pump

Thank you for your reply
There is no fuel coming out of the high pressure pump as I crank the engine.

Meanwhile the client told me that when the fuel tank is below half of the capacity the car starts and works better. So I brought him a brand new original fuel tank cap having ...
