Hello Everyone, we are a Family traveling in the us and our bus wonít start. We are at Yellowstone NP and the mechanics here donít know what is wrong with the bus. It was in idle and it just stopped. Now it cranks but wonít start. Diesel filter good and fluid ok. We take good care of it and do all the maintenance on time. If anyone has any ideas or knowledge of this kind of problems. Or knows really well this kind of motor. we will appreciate any help.

Here is the info on the bus: 2004 International CE200 Short Bus
T444E 7.3 Turbo Diesel with an Allison 2000 automatic 5 speed overdrive transmission. Hydraulic disc brakes

Does the scanner communicate?

Have you performed an injector buzz test.

Has the camshaft position sensor been checked or changed?

With a scanner you would see an RPM .

What is your HPOP oil pressure vs. desired

I'll be frank here. If the mechanic can't figure out a T444e. Look for another mechanic.

Gotta run the codes, that's your best bet to get started on diagnosing issues with any electronic engine.

Fuel & fire.



If you're not starting, then you have a problem with one of these systems.



Mechanical motors were pretty easy, but now all the electronics safety **** will freak out when the electrons are unhappy. But it still all boils down to fuel and fire.
