Why does my dt466e take so long to start?

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.

Why does my dt466e have no oil pressure?

Pulled the tube and checked it. It was fine. Pulled the engine oil pump (on crank) and it looks worn. Light grooving and some wear on the gear lobes in the pump. Leaning towards that being it. With it not filling the front cover i don’t think it’s the pressure Reg but i could be wrong.

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.

What is diagnostic trouble code 332 on dt466e?

Diagnostic Trouble Code 332 will be set by the ECM if the signal from the ICP sensor is higher than expected with the engine not running. If the ECM detects this fault, the ECM will ignore the ICP signal and will operate the IPR with fixed values determined from engine operating conditions.

How does the high pressure oil pump work on a DT466?

The high pressure oil pump that operates the injectors is fed oil by the lube pump through a reservoir in the front gear cover. When you start a DT466E after an oil change it will start and run for a few seconds and quit then after a few seconds of cranking it will start again and run the oil pressure gauge will start to move at the same time.

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.

What are the crank times on a 2005 DT466?

We have 2 of the 2005-2006 DT466s, when cold, long cranking times then an unnerving high speed rev up and black smoke till they settle down are the norm. They are one of the reasons we switched to 5W-40 motor oil, both to make me feel better about the cold high speed rev up and to help with the cold cranking speed.

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.

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.

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.

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.

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??

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.
