Pal of mine - the injection pump on his Yanmar YSE12 has failed ... he's followed all the service / repair videos / instructions - but still engine will not start. The fuel pump is basically not pumping when assembled. If the output ball valve is removed - it pumps, replace ball valve - its near stopped. We think its the stroke bore worn out.
Looking for a 2nd hand unit.
