In the workshop we have 3 different manufacturer vehicles with a diesel fuel problem. Two have been fuelled with Petrol. I am trying to find out information, however I having difficulty finding the answer. On the high pressure fuel pump at the engine, remove the tank return pipe and insert a pipe to a collection container. Turn on the ignition, the tank pump primes and stops when the pressure reaches about 4-5bar at the fuel supply port of the high pressure pump. Am I right in saying there should be no diesel going back to the tank from the high pressure pump until the engine is cranked? What is the expected resistance of the return valve solenoid / pressure regulator in the high pressure pump? Using Alldata and it is not mentioned on the 3 vehicles.
