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 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.
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.

Where does the coolant go when the engine is turned off?
When a vehicle overheats, or after the engine has been turned off after a long ride, an expansion valve opens inside the radiator cap to allow pressurized coolant to enter the overflow reservoir.
