thanks for reply engine fault codes p0832 clutch pedal switch a cct high p2290 injection control pressure too low abs u0401invalid data recieved from pcm ehb ecu u0100 lost comms with engine control ride level u0416 invalid data from vehicle dynamics control module all terrain u0401 u0416. fuel pressure and flow were taken using coda combined guages after breaking into what i think was the supply line to the hp pump.pressure initially 8psi flow 3.0 ltrs/min reving in the garage pressure varied between 8psi and 1psi although flow remained above2.0 ltrs/min.on the road pressure remained low 1 or 2 psi flow remained @2ltrs/min until the fault appeared then flow fell to below 0.8 ltrs/min.momentarily clamping the outlet of the guage the reading increased to 60+ psi. not sure if i am taking the readings from the right places cos there are a lot of tee junctions in unexpected places hope thats helpful paul
