Zd 326 turns over but wont start

[Kadabrada]

Please help tried everything it will turn over but will not start. Glow plugs are working, put new starter on it. I’ve looked all on line and everything they say that could be wrong isn’t the issue with mine. Fuel lines have been cleaned. I’m at a lost. Thank y’all for your time and help

Fuel cut off solenoid? Getting fuel to the injectors? Did it just quit running one day?

Yea need a little more information?

 

[Russell King]

Start with information like engine type (diesel or gasoline fueled)

then describe what “everything “ you did really means so that we won’t be telling you to go through the same process again.

if it is gasoline fueled does it have any spark to the plugs?

ZD326 is diesel. I just picked up a ZD331 a few weeks ago

Remove the fuel hose connected to the injection pump beside the throttle lever, put the end of the hose in a catch can and turn on the key switch to the RUN position. Do you have a good supply of fuel from the hose?
If not, you have a plugged hose, tank outlet, filter or the electric pump has failed or not running.
If you have a good flow, reinstall the hose onto the injection pump.

Turn the key switch on to the RUN position and listen for an audible click from the fuel shut off solenoid on the injection pump every time you turn the switch ON or OFF. If you do not hear a click, see if you have battery voltage to the solenoid with the key switch in the ON position.

If there is no voltage, you will need to find the electrical failure using the schematic that is attached.

If you do have an audible click, loosen on or two of the fuel injection lines at the injectors in the top of the cylinder head and crank the engine over for a few seconds. There should be fuel squirting out around the nuts on the lines you loosened.

If there is no fuel at the loosened nuts, remove the fuel shut off solenoid from the injection pump. It is secured with two short bolts. With the solenoid removed, you would need to pull the small shut off lever on the injection pump that is next to the throttle lever, holding it until the engine dies completely.

Now, crank the engine to see if it will run after snugging the line nuts back up. If it does, you have a failed fuel shut off solenoid.
If it doesn't, you have a mechanical failure.

With key on do you hear the fuel pump running? Grab a flashlight and look at the pre-pump fuel filter and post pump fuel filters, they are also near the battery. Also if no fuel try shifting to the other fuel tank.

It’s diesel. Check switch glow plugs pressure check fuel lines etc

Thank you will try today

All that’s fine checked the lines glow plugs etc. yes just stopped running. Will turn over but that’s it

At this point, I would remove the fuel cutoff solenoid from the injector pump and see if it started.

If it starts you will have to hold the solenoid in place to shut it down.
