Recommended Posts

l have Hino 300 diesel truck which has manual diesel pump with a solenoid. The truck is failing to start it seems as if there's no power coming to the solenoid. after diagnosis l got the following obd2 trouble code P0627 fuel pump control/open.

the vehicle was also involed in an accident (side smash by the diesel tank) prior to this problem.

the SCV is normally shut off tipe -- it means when at no 12V signal the valve stem remains closed not enabling pump to suck diesel.

youo may have an issue with control solenoid burning out. You can easy test it using multimeter on resistance of coil. if you have firm sero then it is coil issue.

checn and revert
