Diesels usually have a fuel shut off. Mine is a big t-handle next to my gauges.

Post pictures of your dash. School buses are different. I have one bus that also has a T handle for shutoff.

Diesel engines having no electrical ignition circuit can only be shut down by either cutting off the air or fuel. Newer arrangements typically use a solenoid that is connected to the key that closes the fuel flow when the key is move to the "OFF" position. Many older units have a manual push/pull cable or rod on the dash that does the same thing...cuts of the fuel. Given that a bad solenoid can cause expensive problems, I have removed the one on my Cummins 4BT and replaced it with an old style all mechanical rod. It will be located somewhere on the pump and looks like a throttle type lever. Not knowing how your bus is arranged, the other end could be anywhere but is usually on the dash. The one on my old BB was a big, red knob. If the system uses the electrical solenoid...that is a different matter as the solenoid and/or electrical connections could be faulty. Best bet there is a diesel mechanic or a LOT of reading.

Good luck with it.

okay, I'm going to work on the bus today, I'll take some pictures. It really boggles my mind that I was able to shut it off using the 'lever' or whatever it was and just coulnd't find it now. Thanks.
