Had a bit of time to look a bit deeper,first two captures are the pump position sensor (middle white plug)just like a good old crank sensor,looks ok ,maybe voltage a bit low on tickover ,but will have to look at another to compare. Third is from the spill solenoid ( grey plug) Here i,m not to sure what i,m looking at . this was at fast idle ,there is a third ramp on idle(like a secondry injection) that disapears just as the knock comes in. Customer,a vet, needs it back , so will have another look next week and may have a look at the circuit bord on the back of the pump as the fault code is bringing up low voltage and maybe a burnt post as they are prone to this.
