well i don't know much about diesels but she ran good 2 days before 1250 miles only stopped for fuel this morning went out checked oil and coolant she started up fast no smoke sounded good then just stopped would not start should i try some spay or whats the first thing to check thanks

 

The only thing unless its super major that will cause our engines to die is lack of fuel. I'm sure you are either out of gas or aren't pumping any fuel into your Injection Pump -IP.

Here is a quick diagnosis.

1. Make sure you key is off so you dont burn up your glow plugs.
2. Pull off the little wire from the solenoid on your passenger side fender (inside)
3. Crank over your engine with a screwdriver while holding the the needle in on the valve (the valve is a tire-looking valve on your fuel filter.
4. Crank over until fuel starts sputtering out.
5. REconnect little wire to solenoid.
6. Turn key and see if it starts. Mine took 10 seconds to start.

Cranking 20-30 seconds and let set for a minute or two so you dont burn up your starter.

There are several of us with the same problems. First thing is to plug the line that goes from your filter to your injectors (#2 and #4 i think.) plug with nonthreaded portion of bolt or whatever. I took a 1/4" bolt and cut off the threads with large wire cutters and a hammer (hammer to help cut the bolt)

Plug the hose comming from the injectors too. If you replace the line & T fitting with one piece you will most likely dislodge the injector o-ring seals and probably have the same problems.

your engine sounds like it is just loosing its prime and the fuel is running back to the tank. your system is like a straw and water. if there is a leak at the top, all the liquid will run out of the system.


You dont need spray, and I wouldnt recommend it anyway since the glowplugs could ignite it and burn up you or your engine.

Always remember this! Diesels need fuel and timing of injectors. Our diesels dont need much more than that (no cam positioning sensors or crap like that) if your engine dies 98% of the time it will be a lack-of-fuel problem.

I hope this helps, post up results of the cranking-while-opening-valve technique and tell us what you have found out.

good luck,

Jeremy

 

Don't use starter fluid on IDI diesel truck with a 21:1 compression ratio. It is the equivalent of lighting a stick of dyonmite inside your engine. You could do some serious engine damage.

You need to figure out why you are not getting fuel to the engine.
