Im working on a 580 super l that dies under any kind of load....first i put a hyd gauge on pump outlet it stays at 0 psi if your not using anything. Turbo spins free no cuts in any air hoses also almost no smoke except on start up. New fuel filters and air filters. New suction hose from tank to transfer pump. Groff tractor installed a new injection pump which didnt seem to fix anything. I believe timing is ok because it fires right up. I made a banjo bolt with a test fitting right into the inlet of injection pump pressure is bouncing quickly from 8 to 30 psi. I am running out of ideas and i also dont want to blame the injection pump but it acts like the govenor isnt working. Any ideas would be appreciated
