Our church bus is a late 90s with the DT466e. We have been having trouble with it dying after you start it.
Does anyone know if this engine would have glow plugs? I looked all over the engine and could not find any glow plugs, GPR or any wiring leading under the valve covers.
IIRC the 466 from the 1990's are traditional direct injection with a side mounted injection pump (might be thinking of the old I6 360). Easy way to tell is are their 6 lines running to a pump? hahaha
I never ran a 466 in my busses but the ones I ran (subbed for others) had a intake grid heater.
How long does it run before shutting down? Last filter change? Does it have the "rock catcher" before the main fuel filter? Looks like a 1" wide x 3" long cylinder that unscrews, has a cleanable filter inside.
According to this wikipedia page: Navistar DT engine - Wikipedia, the free encyclopedia - the "E" means that it's a HEUI engine, used starting in 1994. Alas, no info on whether it's glow-plugged or intake-heated. All the external links from the entry are dead.
I don't drive the bus, but I'm told that it starts fine and runs really good for like a minute, then dies like you turn the key off. The it cranks for a while before restarting. When it does restart you have to play with the throttle to keep it going for about 10 minutes. The day I stopped to look at it, it started and ran like a champ with no hickups.
The oil, oil filter and fuel filters were changed in mid May when we purchased the bus. I saw the CPS and what appeared to be the HPOP with an IPR. The lines attached to the 'HPOP' went to a nearby filter. I assumed it was the oil filter, but the driver told me he got fuel from the filter when he was messing with it. (I didn't check myself, probably should have.) I couldn't find the injectors, so I assumed they are beneath the valve covers, but I couldn't find any wiring that goes in them either. The computer is mounted to the engine so its possible that the wiring goes out the bottom of the computer directly into the valve cover, I guess.
I figured if it kept acting up, we would replace the CPS.

Isn't the DT466e an HEUI engine?
Yes HEUI engine with injectors nearly identical to ours. Can't remember if they have glowplugs though.
Ok. Thats what I thought. There is no wait to start light, I don't think it has a grid heater either. I didn't notice any thing extraordinary on the intake.
What do you think about it dying like that?
Also, does anyone know where the pass-thru harness should be?
Unless that's synthetic, 6000 miles is pretty high miles for oil that does hydraulic duty as well as lubrication. Could just be breaking down to the point that it's doing a poor job maintaining injection pressure. At that many miles, an oil change wouldn't hurt anyway.

not really. most companies do a 10,000 mile oil change schedule with the larger trucks.
