2.5 na. Engine dies ?

While driving engine will stop, I push clutch in let it out truck restarts with the movement of vehicle. Has happened three time so checked fuel diesel looks as when I changed filter clean no water in either filter or tank.
I was told starter switch, loose wire or? Kill switch?

Anyone have this happen?

Sounds like your fuel cutoff solenoid or the wiring on your injector pump may be failing.

Yea. Check electrical first. Ignition switch and fuel solenoid.

Wire a temporary led warning light off the shut-off solenoid so it gets power when the solenoid has power.
If the light goes our when it stalls, you have a wiring issue.
If the light stays on when it stalls, you probably have a fuel delivery issue.

Fuel cutoff switch? Is that the round part on the fuel pump next to the fuel intake?
That wire is W white on the diagram the is no wire connected? #73.
I added a new connector & sodered it this time as it was the only thing I could find.
Slightly loose wire been that way for a while.

On the ignition switch did not see a similar wire?

So I could wire from there a light, does that need a power source or ground?
I do wiring just not willingly.

There should be 12V at that terminal with the ignition switch on. Check for power there. The ignition switch end of the wire is most likely white with a black trace. Is this an ex-military truck?

If there is power and it does not run come back for further advice...

Yes this is a x-mod.
& yes there is two w-b wires together at ignition.
Truck runs it was stopping at odd times or going over a bridge twice when there was a lot of vibration? Then another time.

Thnx.

Okay truck does not run, after checking fuel it initially started shut it off.
Now with everything back together it initially would start just not run?
12.5 volts at battery.
11.6 at fuel shut off with key on, got a definite click when I pulled wire off fuel shut off.
Will turn over just not run loosened banjo at top of fuel filter fuel comes out.

Tomorrow may re check & clean sedimentary.
Go talk to diesel mechanic over week end.

You need to put some petal in it while running to purge the air you introduced when you loosened the banjo at top of fuel filter fuel.
So start it with the petal down, lift it up, but keep it running until it idles.
If no idle then you need to install a 12V fuel pump back near the tank to expose any air leaks.

These are a pain to bleed. Open the injection pump bleed screw and crank until you have good girl flow. Then crack the pipe at all four injectors. As you get fuel leaking out while cranking tighten one at a time.

Bleed screw?

. Open the injection pump bleed screw and crank until you have good girl flow.

Where is the bleed screw before I make it worse?
Seems odd did this last year drained both filters & have drained fuel tank before with out trouble starting.

Download the workshop manual. It explains the bleed procedure.

A 12V pump ends the need to bleed.

Even on a 2.5NA? I thought they do not self bleed. There is nowhere for the air to go.

Yes when you turn the key on, the 12V fuel pump pumps and the IP solenoid opens and pushes the fuel through.
If the return line is connected back to the fuel filter via a banjo, it will recirculate some of the air back through the filter, but the banjo connection on the return line going to the filter head also goes back to the fuel tank and will eventually clear the air by sending it back to the tank.
Similar scenario to a TDI.
Worth noting that when the banjo where the return line connects to the filter is replaced with a solid bolt, the air bleeds much faster.

With the 2.25 Diesel, the fuel shut-off has to be in the run position for it to self bleed.

I have been looking for that page in the shop manual for a while?
I finally found it again, like you said.
I was I believe operating the fuel pump assbackwards.
Could hear the air bubbles moving continued until it was quiet.
Have not tried starting later.

Thnx

Evidently a loose wire can cause problems, truck runs fine no more stops of engine.

I did clean the sedimentier & checked fuel filter. The sedimentier was full of gunk I cleaned out, otherwise the fuel filter was as clean as it was installed.
Should the fuel filter still be changed annually if in use with sedimentier? Or?

Another fine example of a working sedimenter!
