Hi all ,new to this . The issue with my 428b is fuel will not go through to the injectors , had it running in the shed checking tyres ect , drove out of the shed about 30 meters uped the revs and it just died . Things I have done so far , changed filter ,bled to injector inlet ,fuel flowing from injector pump outlet and filter return T , there is a 13mm head bolt on the side of the pump body which fuel only drips out at best when hand priming , checked and cleaned screen in the pump inlet , check pump turning while cranking through timing window ,all ok ,removed top tested shut of solenoid and linkages all seem to be good and top of pump was clean no signs of wearing parts , hot wired solenoid while cranking in case machine wiring is faulty , still can not get any fuel to injector lines , put some air into pump inlet and fuel and air came out of that 13mm bolt mentioned earlier but nothing will flow out of it while hand priming and I can also her fuel returning back to tank when priming . Not sure what to try next ,any clues? Cheers
