Engine keeps running

Have 2001 Itasca, 220 caterpillar diesel. When I turn the ignition off, the engine keeps running. Any idea why this is happening.

Thanks

I'm going to assume this is a typo. Never heard of a "220" CAT, especially in this era coach. Most likely a 330HP 3126 CAT.

Usually there is an inline valve to shut off the fuel supply"

Nope, no inline fuel valves anywhere on all the CATs I've seen and or worked on in this era coaches. I installed TWO. One before the rear fuel filter and one after it. Now, no possible chance of air entering the system and or, fuel draining back into the tank, as it did prior to my installation of the fuel shut off valves.

My 2006 Cat 350 does this every so often. I have changed the ignition switch, been over every thing I can think of, as has the local Cat shop. I merely turn the engine batteries off. My fuel pump is electric so that kills the engine. Problem hasn’t cropped up for a while. So I don’t know if it’s fixed or ???? Good luck.

Your fuel pump is ELECTRIC? May I ask what year/make/model/chassis coach you have that has an electric fuel pump in a CAT equipped coach?

The reason I ask is, our coach, an '04 Itasca Horizon 36GD with the CAT C-7 330HP only has a lift pump that is attached to the back of the HEUI pump. Of course, neither of those are electric. Just wondering.
