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.

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.
