Need Help, Brand new to the Deuce!

[69DeuceJuice]

Hi I’m Trying to get a M35a2 non-turbo to fire up and run so I can drive it home. Turns over fine and will run on ether but dies a few seconds after taking away the juice. Electric lift pump is working, has fuel in all the filters and has been bled. Has fuel going to the injection pump, but little to no fuel out of the injection lines. No fuel movement in the return lines or the flame heater. I tried for three hours to bleed the injection pump and lines but stopped due to a hot starter and a hotter temper. Please help.

So fuel all the way to the injection pump but nothing leaving the injection pump to the injectors when cranking is that right?

That at least narrows you down to the IP with your troubleshooting. Admittedly not up on IP troubleshooting but I have to imagine there's a pretty good process for diagnosing where in the IP things are falling down; fuel shut off not disengaging something gummed up, a spring or rod not moving freely etc.

The button under the hydraulic head probably came off. Search Hydraulic head and you’ll find a lot of information on this.

Is the fuel shut off in the cab pushed in ? simple stuff first

I’m guessing a sticky/stuck fuel shut off

Yeah we check that multiple times as we covered our bases a bunch. Externally everything moved freely and seems fine. This truck has sat about a year and a half since it last ran.

I will definitely look into this. Do you know what that button controls? Is it pump output pressure?

The button controls the quill inside the hydraulic head which in turn controls the timing of the injection of the fuel to each fuel line. If you have fuel to the injection pump but no fuel out of the injection lines it’s usually the bottom came off. You can check this by taking off the center bolt of the hydraulic head and putting a pencil in there to see if it moves up and down when firing it over. No movement means the button fell off.

But did you check it INSIDE the injection pump?

My vote is still a stuck fuel shut off…

How to remove the Fuel Shutoff Rod on the IP

Was your truck running before the fuel shut off stuck? As far as removing the rod its pretty simple. When you remove the shut off cover you will see the arm attached to the fuel control rod. There should be a bridge piece with 2 screws and safety wire going through the screws. On the bottom...

Say about a year a half from the last time it ran the guy said I’m buying it from

Hopefully it's cheap since he is selling as a non-runner.

Have you removed the fuel shut off cover yet, and associated linkage to verify it moves freely and correctly? A very common 5min job could save you an hour or two from pulling the HH.

THANK YOU TO EVERYONE THAT REPLIED !!!!! I got the hydraulic head off and sure enough the button for the pump was sitting in the bottom, I pulled it out cleaned and lubed everything put the button and clip back on and put everything together and it fired right up no ether or anything. Now all I need to do is change the fluids and bleed the brakes but she’s home and I need a name for her!!!
