    Help! NO FUEL/ Fuel Pressure

    Hello,

    I need some advice as I have tried everything that I know of. The 84 Dodge TD stalled on the highway and won't start. It turns over but won't run. Checked the glow plugs, battery, fuel filter, full tank of diesel, timing marks line up. Diesel comes out of the injector lines but there is no pressure. Removed the fuel shut-off solenoid after finding that it had a faulty connection. and found the piston slightly stuck due to a rubber washer. removed washer and it makes the "clicking" sound upon installation. Still wouldn't start. So I took it to a shop and they said that there is not enough fuel pressure and that the lift pump/ fuel pump would give it pressure. As far as I know there is no mechanical lift or feed pump before the fuel gets to the injection pump? Am I wrong? Could it be something else? What about a clogged fuel filter at the fuel tank? Any immediate help is very much appreciated. Thanks

    There is not a lift pump in the fuel tank on these trucks. The injection pump is the lift pump. When my fuel cut solenoid failed I experienced very similar symptoms to those you are describing.

    Weird. I can hear the solenoid clicking and even took it out, grounded it and put electricity on it and saw it move. You can't get them from rock auto, I read somewhere that the volkswagon TD have the same ones for around $20. Not sure if that is true. know where else to get one?

    They found out that there is something wrong at the injection pump. The fuel comming out of the injector pump is really low PSI. They said that one or two was regular but the rest were low. They got it to run like that but it sounded real bad. I wonder if something got sucked into the pump when the fuel cut solenoid malfunctioned? Is that on the intake or outtake side of the pump? Anways I have a spare pump that looks like it is in good condition, I would have to swap over a few parts, is it that hard to get the new pump timed to the engine? Or is it worthwhile to take a part the pump and see if I can find out what is wrong insde? anyone had a similar problem? Thanks for the help

    Check out this post! http://gnarlodious.com/Vanagon/Bosch_Pump/-Rebuild.html
    It explains how to basically rebuild the pump. All I need to know now is how to set the internal pressure. Anyone attempted this before? pitfalls?

    IMO, you will still need the pump specialist to calibrate the working/internal pressure. the write-up you posted only shows how to reseal the pump. plus too many internal parts to deal with. but that's just me.

    swap out with your other pump.........timing is crucial but settable. you will need a dial indicator for this pump. i forget what it cost but there out there. i gave mine to Kane when he got the truck...

    Do you know what pushes on the dial indicator? Is it fuel, air or some kind of mechanism? I have a dial indicator that has a magnetic stand, so I think that maybe that would work by setting it up on the block to make it sturdy. Unless the connection needs to be air tight to make the reading. Does fuel come out when you remove the bolt to make the reading? Thanks

    Rebuilding your pump is not one area that I recommend cutting corners. You need to take it to a professional rebuilder that only works on pumps. Don't just take it to a diesel shop, take it to the specialist. It should cost between $400-700

    the correct dial indicator thread into the back of the pump. the plunger in the back is what you measure off of.... idk,,,, maybe a magnetic indicator may work... it has been a while sine i last did this.

    Ok so this morning I start my truck, let it warm up for 10-15 minutes and proceed to leave for work half way down my drive way it starts acting like its running out of fuel so I get it back in my shop and put some diesel 911 in the fuel filter (its been single digits the last couple mornings) thinking maybe its gelled. That didn't work so I replaced fuel filter, cleared the lines to tank w/ air compressor, re-primed at fuel filter, bled at injectors, and it still won't run. Praying there is another step I can exhaust before taking to pump/injection specialist. Any input appreciated

    I would look at the lift pump first. Unless it's not starting at all. There is a good chance the cold did somthing to the fuel lines and you have an air leek. It was running before it went hay wire. So it must be on the low pressure side.
