Hi guys, just had the ecu check light come up. we have an 07 120 with a d4d. checked flash codes and got code 78 up. not sure where to start looking for the problem. have a feeling we may have a fuel leak into the sump as it appears our oil level has increased. have looked at the fault table posted here but not really sure what could be causing the fault. any help with this would be great.
thanks guys

Hi,

I copied a post some time ago on Pradopoint listing fault codes. From my copy it appears you have a fuel pump issue - see below. The P code is seen on a Scan Gauge and the number in brackets is seen using the engine check light.

P0627 (78) - Fuel pump control circuit (open/short/failure)
P1229 (78) - Fuel pump fail.

Thanks to whoever originally posted the codes.

cheers, looked through the codes and got that far, was wondering which pump to to check and how to tell if there is a problem. unsure if its the fuel tank based pump or the mechanical pump.
