I've got a MF470 shovel loader with a 236 perkins we rebuilt. It has an electric fuel pump on it and as near as I can tell we have all the air out of the system. There are two bleed screws on the side of the pump body and fuel pours out of them with no sign of air yet there is nothing coming out of the injector lines? We had it running very briefly (20 seconds) before we took the engine out 6 months ago so I wouldn't think anything would have got gummed up or anything. Turned out cylinder 4 piston got melted and scored up likely from a bad injector. Had them rebuilt and the shop said they were in pretty bad shape so I'm just thinking the pump likely maybe as well or if there is still a bit of air in it I can't get out? Pump was never removed so it shouldn't be a timing issue. Little reluctant to use ether on it to get it going. Ideas anyone?
