RE: engine cuts out
A diesel engine is fairly simple, which means if it cranks over at a reasonable speed you are left with a fuel problem.

Fuel issues are divided into "delivery" (fuel pump and filter) then into electrical issues. (fuel solenoid and the power supplying it)

Two other things to consider would be the integrity of the fuel lines (cracks can let air into the system) and the condition of the injection pump itself. The latter is something that the DIY type can only guess at by reasonable deduction. Generally speaking a tired injection pump will not cause the engine to stall but internal leakage can make it hard to start after sitting a few hours.

What do you do to get it started? That will give us a clue.

RE: engine cuts out
John, I will see what info I can get for this vehicle. My Alldata program does not show this year and model. I assume it is due to the fact they were not sold in the U.S. From your email it looks like you are from the U.K. I will post back in 12 - 24 hours.

RE: engine cuts out
Since we don’t know a lot about this engine I would like to add to the list of general things that can cause problems with diesel engines.

Many diesel engines have a secondary, or transfer; pump that delivers fuel to the injection pump. I have seen these in a weakened state that will work fine one minute and let the engine die a minute later.

Some diesels use the motor oil for hydraulic pressure to activate the injectors. I have seen this type of engine repaired by a simple oil and filter change.

I have seen other engines that were completely computer controlled and a sensor was sending bad information to the computer or the computer its self was bad. Most of these engines have some sort of warning light like the “Check Engine” or “Service Engine Soon” lights. On this type you can usually pull up some useful information with a scanner. Usually a cam or crank position sensor is the culprit in these.

I have seen dirty fuel plug injectors & once pulled an entire T-shirt out of a fuel thank. This was on a small bull dozer. It would run fine for a while & then just start to sputter and die. As you would head toward the service area it would take off and run good again. What was happening was as the machine leaned back and forth the shirt would slide on & off of the fuel supply line. Somebody putting something other than fuel in your tank?

I have seen chunks of the turbo fly through the valves and only cause temporary sputtering and stalling until the whole turbo blew apart or locked up.

As “Rupe” mentioned, some extra information could really be helpful. What do you do to get it started? Are there any types of warning lights on? Is there one particular condition that seems to cause the problem? Is it cold where you are at that could cause gelling? Did this start right after some other repair was made? Anything that you can think of that might narrow things down.

Please keep us posted on your progress.
Thanks, Garner
