    No fuel at the injectors

    One other thing.. U can remove the line off the top cover on the pump.. THEN, remove all the fittings..(9/16 wrench) If done correctly, you’ll be looking at a hole in the to of the pump.. VERIFY the solenoid is clicking.. Then take the line and fittings out.. NOW loosen the lines AT THE...

    No fuel at the injectors

    1st, u r NOT going to get fuel out of the injectors by hand pumping the primer.. The primer is to fill the filter and to push fuel TO THE PUMP INLET.. The only way to get fuel at the injectors is to crank the engine with the starter.. U CAN run a jumper wire from the battery + to the solenoid...

    John deere low fuel pressure 319d

    Can u find out AT WHAT PSI it derates at and maybe lower it a smidge.?? Depending on how long the run is from the fuel tank to the supply pump and inj pump, I’ve seen long runs where the rubber line gets sucked down..& throws that code..

    Cat 1986 426 Backhoe Loader Won't start , again

    I understand.. but unless u find someone that’s sympathetic to your problem, it’s still gonna take that long.. You’ll be days ahead if u just buy one off the web.. If the head and rotor is in fact seized, you’ll only get half of the core charge back.. If u get it done locally, they’re gonna hit...

    Have u checked the shut off solenoid.?? Remove the solenoid (15/16) and see if u can get the plunger and spring out and screw it back in and rebleed it.

    To b absolutely sure, u can take the 4-5/16 screws out of the “end plate”, remove it and bump the engine to see if the center turns.. All it takes is a “bump” to tell.

    One last test.. Remove the inlet fitting if it’s a 90*.. Fill the inlet hole with fuel to the top.. Crank the engine over a couple revolutions.. now go look at the fuel in the inlet hole.. Is it still there or did it get sucked down..?? If it’s still there,‘u have problems..
