Is the DT466 truck getting hard to start?
Is the DT466 truck getting hard to start?
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. There is nothing else wrong with this truck, this is the only problem it is giving me now.
What should off hand rpm be on DT466?
If it cranks don’t rev it unless you have a gauge to handle about 3000psi. Off hand should take close to 600psi to start. also you can pull the valve cover and apply shop air pressure into the rail and look for air bypassing the injectors.
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.
What do the 0-rings on a DT466 mean?
Looks like you need a set of injector 0-rings. those codes refer to loss of injection pressure. The long rail on the side of the head is the High pressure rail for the injectors. If you have a gauge that goes up to 1000psi or better you can tap into the pressure sensor port and check cranking pressure.
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 my DT 466 getting hard to start?
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. This is about a 2 hour job at a dealer. Did you check ALL fluids accurately?
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 HPOP on a 1999 dt466e?
On the left side of the engine mounted on the back side of the front cover is the high pressure oil pump. Its also right above the air compressor ( if equipped) or ps pump. On the hpop there is a valve near the bottom of it.
Is the DT466 loss of power really that bad?
It had very slow acceleration and it would die quickly when going up hills. it seemed to struggle heavily on hills actually. The clutch is fine, just got adjusted about a month ago, no smoke, just low power. Air filter is clean. Oil pressure is good. Temp was fine. No lights came on.
When was the last time IH 4900 had no power?
This topic contains 3 replies, has 2 voices, and was last updated by Brian Sanderlin 4 years, 11 months ago. So my IH 4900 was acting like it had no power towards the end of my route.

What makes a 2003 International 4300 sputter and Miss?
I have a 2003 International 4300 with a DT466. I just had all the O-rings on the injectors replaced along with the wiring harness that goes to the injectors. Now once the truck gets up to running temp it starts to sputter/miss. Truck runs GREAT cold but once warm gets worse.
What makes a DT466 diesel truck go limp?
The engine is new, the injectors are all new, the MAP Sensor is new, the Baro Sensor is new, the Cam Sensor is new, the High Pressure Oil Pump is new, the fuel sensor and regulators are new, the computer is new. The truck will crank, and then go into a limp mode and blow tons of white smoke out of the stack. Any ideas would be appreciated.
How often does a DT466 give up the ghost?
The only difference betwene the two is how light your pocket will be. If its not the issue youre only out 25 or 30 bucks. Had mine go a couple times they usualy give up the ghost every 50,000 to 100,000 as long as you dont run too hot and driving conditions.
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.
How long does it take to start a 05 dt466e bus?
I have 11 05 DT466E buses in my fleet. Out of the 11, only 4 like to start. The rest have extended cranking times. sometimes it takes up to 45 seconds of cranking to get them started, and the cold only makes it worse.
If it cranks don’t rev it unless you have a gauge to handle about 3000psi. Off hand should take close to 600psi to start. also you can pull the valve cover and apply shop air pressure into the rail and look for air bypassing the injectors.
