Why does my dt466e no start-fuel problem?

Got that all fixed. Realized that my primer pump would leak when I would pump it, replaced the entire assembly. Filled both filters, truck fired on the first try. Now today go to run a call, cranks and cranks wont start. Gave a shot of ether, fires but wont run on diesel.

Can a 2004 DT 466 E start on its own?

I’m working on a 2004 DT 466 e with the variable turbo that won’t start on it’s own. The fuel pressure at the manifold will only get up to about 20psi after exteneded cranking. I replaced the lift pump and it didn’t change one bit.

Where is the fuel pump on a DT-466?

JaymZH2 wrote: fuel pump would be my guess. not sure on the older ones, but the newer DT’s it is on the drivers side mid block towards the front. a couple bolts a 2 lines and your done. I have a 2000 4700 DT-466, would what you call the fuel pump be the same thing they call the “high pressure pump” in the book that the lines from the filter go to??

Where is the crank position sensor on a DT466?

If not replace the crank position sensor located on the bell housing on the driver s side . Pull the from fender off and you will see it . It is a two wire sensor with a square connector . Is it above the starter?

What should fuel psi be on dt466e International diesel?

Usually when we get no start cold but fires and runs after using ether it might be injectors, but you need to do the fuel checks I posted and let me know. If you don’t have a fuel psi gauge, autozone loans them out. I like to have around 60psi I have seen them run ok above 45psi.

Why does my dt466e take so long to start?

The high psi oil system, in a dt466e you have high psi oil that fires the injectors, and sometimes the pump can actually bleed down overnight causing it to take forever to start, the only way to check that will be let it sit overnight and there is a temp sensor in the front cover/ drivers side . it is right in front of the oil/fuel pump.

When did the Navistar DT 466 engine come out?

DT 466E (7.6L): Introduced in 1994, added electronic control to previous, non-electronic DT 466, superseded by model year 2005-and-later DT 466 with variable geometry turbocharger (see below). Also changed over from mechanical fuel injection to electro-hydraulic unit injection (HEUI). DT 466 Family, Model A175 and A190.

What causes an injection pump to start up?

This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak. Ready to sell? CarMax buys all kinds of cars

When did Navistar switch from mechanical injection to HEUI?

Take Navistar’s DT466-based engine for instance. It utilized mechanical injection from the 1970s to the early 1990s before the same overall platform was adorned with the HEUI system. After the switch, there was no change in hard-part durability.

Can a HEUI injector last as long as a mechanical unit?

With proper maintenance, a HEUI injector can last just as long as a mechanical unit, and many HEUI injectors outlast the newfangled common-rail injectors found in the latest diesel engines on the market.

What’s the oil change interval for a 6.0L Power Stroke?

In the 6.0L Power Stroke’s case, observe the “Special Operating Conditions” oil change interval of 5,000 miles (or 200 hours) rather than the 7,500-mile interval recommended under normal operating conditions.

Why does my international 4300 DT466 not start?

If theres any air in it at all, it wont start. . The daytime running lights (DRL) and low beam headlights are inoperable. The highbeam headlights, markers and all other lights function properly. I have checked the fusebox in the engine compartment and above the glovebox and am unable to locate either a DRL/headlight, fuse or relay.

Where does battery power come from on dt466-mhh?

There should be battery power on 2 of the terminals. Those are the clean power wires. When you turn the key on, it sends an ignition voltage signal to the ECM. When the ECM sees that signal, it then sends a ground signal to the IDM relay to give itself battery power.

Why is the ECM not working on my DT466 MHH?

If not then ECM not powering up. I have saw a few times with the fuse box located out on the driver side above the steer tire give fits. The fuse holder will get loose and not make good connection. In that fuse box on the fender. Check the IDM relay. There should be battery power on 2 of the terminals. Those are the clean power wires.

What to do if your diesel engine wont start?

Are there any issues with the 2000 dt466e?

Walkerv thanks for the heads up on the injectors. It’s not noticeable on cold start. It runs perfect thru all rpms until it gets to 180. TVA it starts fine either way. I was running it last night to get it to temperature, it seems to idle ok after 180 degrees.

Why is my 2000 dt466e losing coolant?

If cooling wasn’t holding pressure it’s either A leaking externally outside the engine or B going into the engine which would show up in oil or you would smell it coming out the exhaust and he said he doesn’t see anything in the oil. Plus would be losing coolant too. It’s not losing coolant and the oil i drained out was good.

Why are my cranks and cranks wont start?

Now today go to run a call, cranks and cranks wont start. Gave a shot of ether, fires but wont run on diesel. Pumped the primer pump, got hard tried again.

Why does my dt466e diesel engine not start?

DT466E international diesel wont start… Will it stay running, after you ether it? Or does it just die out again? Do you have access to a scanner, any engine light on? Does the tach read while you are cranking? Can you use the hand primer on the filter base to try and prime system, if it does not get hard to pump you are most likely sucking air.

Why does my dt466e have diagnostic trouble code 124?

Diagnostic Trouble Code 124 may be set due to an open or short to ground on the signal circuit, a defective sensor or an open V REF circuit. When code 125 is active the amber ENGINE lamp is illuminated and the odometer displays the message WARN ENG.

Where is the starter on a 2004 DT466?

Why does my DT 466E engine have low oil pressure?

If the injection control pressure is low it may be the injector o-rings, a defect in the injector itself (poppet valve) or worn out pump. The symptoms of a low oil pressure to the injectors will be low power especially when hot, high fuel and oil consumption and blue exhaust smoke especially on start up.

Why does my 1999 IH dt466e keep dying?

I have a 1999 IH DT466E that will not stay running. It will start right up and then run from anywhere from 30 secs. to several minutes. It then dies, but will start back up and do the same thing. I have replaced the fuel filter on the drivers side, and the high pressure oil pump is also new last fall.

Why is the wastegate not working on a DT466?

Since it’s a mechanical DT466 (not an E), many of those had a Bosch injection pump with an aneroid valve and a wastegate valve on turbo, both activated by turbo boost pressure from intake. I have seen diaphram go bad on wastegate valve pot which causes the aneroid valve to not get pressure to turn up fuel when under load.

Why does my international 4300 engine not start?

Why does my 466 pump have a hard time starting?

You probably have a leak on your high pressure oil rail. More than likely, needs a new o-ring set. The 466 uses oil to hydraulicly actuate your injectors. Once the o-rings start to leak, the high pressure pump has a hard time building pressure to actuate the injectors. Sometimes it takes 30 seconds to finally build enough pressure to start.

Is the IH 4300 DT466 getting hard to start?

I have an 05 IH 4300 DT466 with 131K miles on it. I have had a small problem with it before, usually first thing in the AM. But now it doesn’t want to start no matter what time of the day it is. If its been sitting for any length of time it cranks and will finally start after about 45 seconds.

Why does my DT engine not start well?

The high mileage on this DT engine was a factor and we changed the HEUI o-rings as well since that also directly effects starting. The o-rings separate the oil from the fuel around the injector and if one of them fails this will also cause poor starting among other problems.

When do you reset the fuel cut off switch?

After speeding over a deep pothole, speed bumper, or after a car accident, you could end up with an engine unable to start. In most cases, you only need to reset the fuel cut off switch, which was activated by the impact. It looks simple, right?

Where is the emergency fuel shut off switch?

Emergency Fuel Shut Off Switch Location on Other Cars On Ford, Peugeot, VW, Citroen, Vauxhall, Subaru, Renault, Toyota and Mazda, inertia switch location is usually on one of the following two hidden places: Behind or below glove compartment, sometimes hidden under the carpet; Under side-panel located next to the drivers’ door;

Where to come when your 6.5L diesel will not start?

Where to come when your 6.5L Diesel will not start! “The PMD / FSD (Pump mounted driver) is by far the #1 cause of 6.5L no-starts (at least 90%). If your truck experienced random stalling like someone shut the key off before ultimately refusing to start again, the PMD is very likely the issue.

What causes a Ford fuel pump to shut off?

If your Ford ever fails to start or stalls on you suddenly, the first thing to check is the inertia fuel shut-off switch. The switch is designed to trip and cut power to the fuel pump in the event of a collision, but you can also trigger it by hitting a large bump or pothole as well.

Is there a way to reset the Ford fuel shut off?

To reset your Ford’s inertia switch, press down on the reset button. Although the location of the shut-off switch varies by year and model, Ford has stuck with a few common spots over the years.
