Just reread this, first make sure you are getting fuel second make sure you have oil pressure when cranking and then on the back side of the front cover on the drivers side there is a sensor. Pull that sensor and have someone crank the engine to see if you have oil to there. Next check the plug on the IPR, it is under the HPOP. They have a tendency to go bad. If that all looks good then you may need to get it towed in somewhere that can hook up a computer to it.

The advice in here scares me. A lot.

A '97 DT466E is going to be a HUEI engine, not an injection pump. It is the same injection system used on a 7.3PSD, if that makes it easier to understand.

First you need to verify fuel in the fuel filter bowl, which is sent through the fuel lines and the primer pump, most of them are electric. The primer is going to be manual on most of them as well. It will likely NOT get hard when priming, easiest way to see for fuel is to pull the filter out, prime and watch for fuel.

Sitting three years is highly problematic, honestly I would drain both tanks give some fresh fuel, and get fuel to the engine.

The transfer pump is likely seized also.

Ditto on the fuel.

After 3 years I wouldn't be surprised of a bunch of water in the tank along with algae.....

My experience with diesels is that they just absolutely HATE the cold. My question is whether or not the thing is making any smoke. If it is making any smoke at all, it is probably getting [some] fuel and just needs a little help with ignition. Try to figure out some way to warm it up if you can. If the engine is nice and toasty warm before you try starting it, I guarantee it will be much easier to start.

If there's no smoke coming from it at all, then you almost definitely have a fuel delivery problem.

KBTConst: everybody knows the "pressurize the fuel tank" trick... good for everything that can't suck air. Snowmobiles with mechanical (vacuum) fuel pumps, diesel machines with tanks lower than the fuel pump (easier to gravity bleed equipment with tank above pump), I've even used this trick to bleed furnace lines from buried tanks.

Good of you for mentioning it though! Thumbs Up

there was some white smoke when cranking it over, i was told that means there is air trapt in the lines

The 466e can have injector problems. One way to check and see is to plug the engine block heater in, wait and hour or so and see if it starts.

The old David Brown in my 580 will puff white smoke all day long and never even kick on a cold day if I try to crank it without heating the engine first.

A cold diesel is a true pain in the a**.

If it loses prime (which happens whenever you change the fuel filters), it can get to this partly-primed state where it will push SOME fuel to the injectors, but not enough to start. Then it will white smoke even if its warm. The easiest way to get the DB past this state is to loosen off the high pressure lines between the pump and the injectors and crank it for a bit. I.e., remove the resistance of the injectors in order to make it possible for the pump to push the air through.

Admittedly, my diesel experience is limited to these older fully mechanical engines (and frikkin SMART -- what a total pain in the a** those are), but the way I figure it is that a diesel requires fuel, air, compression, and heat. The heat is usually provided by the compression, but when really cold, it may just not be enough. If nothing is broken on it, then it should be just a matter of getting that fuel into the system and ensuring that there is enough heat to produce combustion.

Does this engine have open injectors each driven straight off multiple ports on the pump? Or does it use a pressurized rail with electric solenoid injectors? If the latter, a couple of simple diagnostics are to test the pressure on the rail, and put a scope on the wires running the injectors. The scope should show a positive voltage every two engine revolutions for each injector. If it has adequate pressure in the rail, adequate heat to ignite, and the scope yields good results, then its either compression or bad injectors. Sitting for years as it has, I would be considering the possibility of stuck valves.

Fuel, Fuel, Fuel, Fuel First.

Any diesel that sits for 3 years is going to have bad fuel in the tank and even possibly algae. The tanks need to be drained first and inspect the fuel that is removed. If any algae appears to be presents, drop the tanks and clean.

I would eliminate the entire fuel supply first. As mentioned above its going to be ugly. The dts all had a compucheck fitting on the filter housing. It looks kinda like a hydraulic coupler. I went and bought a 12v atv sprayer put a compucheck in place of the wand, filled it with clean diesel and bam you have a 60 psi primer. Cap the trucks supply line and youve solved your fuel quality and prime issues. At least to get it running and go from there. If its smoking FUEL smoke at all I would rule out ecm, cam sensor, and heui issues for now.

same injection system used on a 7.3PSD

That's nice. WTF is a "7.3PSD"??? Or an "HUEI"???

Fact remains that the FUEL NEEDS TO BE FULL IN THE LINES WITHOUT AIR BUBBLES.

 

[matzke3]

Heui- hydraulic actuated electronic unit injected.
Im referring the the high pressure oil system for injection. They typically work or they do not. If its in question they take aprrox 800 psi to fire.
EDIT- safety issue. The high pressure system is capable of deadhead pressures up to 4000 PSI. If its going to be check with a guage it is imperative that the guage and test line can hadle those pressures.

That sounds a lot like technobabble for hydraulic driven fuel pump, pressurized rail, electric solenoid injector valves.... ?? But yeah, it goes without saying that the gauge must be good for the maximum pressure that the system you are testing is capable of producing.

Obviously not, they are still talking about injector pumps.

Guess what? You can't make pressure without a pump and without something for the pump to pump.

Initially I was not going to get into a pissing match, but it is fairly clear you have either no knowledge of how a system like this works, are an old school mechanical injection system kind of person, or just really likes to show their ignorance on the internet with completely misguided diagnostic approaches or poor advice for a system that does not even apply to the vehicle in question.

Simply put, a HEUI (or HUEI, depending on manufacturers designation) system operates with a fuel "rail" surrounding the injector, in Internationals (and Ford)'s case it is a cast galley that goes through the cylinder head that is fed from the filter housing, which has a low pressure fuel transfer pump feeding those from the tank. The injector has a high pressure oil feed which feeds into the head also, when the solenoid on the injector is fired from the FICM (fuel injector control module) it allows high pressure engine oil (up to 4000psi in some instances) to force the intensifier piston down, which compresses the diesel fuel, and atomizes it out the tip.

I can go on and on about the operational strategy here, but the fact you continue to reference fuel injection lines, cracking feed line nuts, etc proves the fact you have no understanding this is NOT a mechanical injected engine.

Seriously, I am not doing this to be a dick, but holy crap the amount of comments regarding this engine being a mechanical pump injection system are ridiculous

[hatefulmechanic]

Its simple diagnostics:

If there is no fuel coming to the filter, its from the housing back, meaning supply pump, restriction in line, or crap fuel. The fact the truck has been sitting for three years remains, this truck is going to have issues that a simple bleed and battery replacement will not address.

you should learn about hydraulic multiplication of force. It's what makes your floor jack and these injectors work. The only pump on these engines have is a high pressure oil pump

 

[gafred]

After you drain the tanks it will need algea killer added, FPPF Killem, kathon biocide diesel. drain water seperator if it has one.

You can start it and run it without load on WD 40, hair spary(flammable kind), liquid wrench they are easier on pistons comapred to ether.

good luck with it...

Not true, on the side of the HPOP is the transfer pump. It is driven off of the HPOP and is replaceable. They do fail but I probably change one of them for every 10 HPOPs. New one comes with the oil pump.
