We are having an issue with our 2001 International 3800 (DT466E). Right now, it will shut off suddenly with no warning. The engine cuts right out and when we try to restart, it won't even crank. No sound, nothing.
Then we disconnect the batteries and reconnect them. Then pull the 40amp fuse that’s in the battery box and reconnect it. Then the bus will crank and turn over, no problem.
We ran the computer, and it’s throwing us three inactive fault codes: PID102-4 (intake manifold pressure out-of-range, low), PID168-4 (electrical out-of-range, low), SID-254-8 (unexpected reset fault).
We’ve had a series of issues over the past four months. I don’t now if they could be connected to this present problem. Just in case they might be, here’s the summary!
June-August - had a mysterious parasitic drain on our brand new batteries. After it happened 4-5 times, we had batteries tested, one was bad. Had them replaced, installed kill switches to avoid draining the new ones.
September - engine was starved for fuel even though it had about 1/4 tank. Mechanic told us the gauge must be off and to always keep tank over half full. So we did that. But then...
October - engine lost power going up hill, shut off. Tank was completely full. Mechanic told us it was starved for fuel. He also said the fuel pressure was reading 0. He replaced the fuel pump, fuel pressure regulator, and starter. He scoped the diesel tank and said it looked very clean inside (no gunk).
Bus drove great for almost 1000 miles, and then the mysterious shut off problem started.
December - engine shut off suddenly when driving. When we tried re-starting, it wouldn’t even crank. We disconnected the batteries, reconnected, and it cranked and turned over. We drove it a mile to a parking spot, turned it off ourselves. 45 minutes later, we then turned it on no problem, it idled for 2 minutes then shut off again. Once again, no crank.
The mechanic tried jumping the batteries, didn’t work. Replaced a solenoid, didn’t work. Unplugged a bunch of fuses in the front panel (not the one in the battery box), and then it cranked and turned over. He tested the alternator, said it wasn’t charging (we had had flickering lights for a while). So he replaced the alternator and said that probably was the problem. He also ran the computer and didn’t find any codes. We drove the bus about 60 miles over the following month (small trips) with no problems, so we thought the issue was fixed.
Then after that month, it started shutting down again. Every time it does this, we disconnect the battery, reconnect, disconnect the 40amp fuse, reconnect, and then it cranks and turns over.
That is our novel. If you have any insights, we would really appreciate it!
