Is there a fuse that is positive only when engine running ?

[preston]

I want to add a lift pump to my 2015 Duramax, but I don't want the it running anytime the ignition is on. Anyone know if there are any fuse locations that would only be hot when the engine is actually running ?

or any other tricks besides having a manual switch in the cab ?

Interesting. Can be done but not easy need a latching relay.

AFter owning this truck for 3 months I only last night discovered there actually is an "ACC" position to the key.  I kept thinknig it was kind of lame to only have IGN and start. So possibly I can find a circuit that is hot only in IGN, that would be an acceptable solution. I have a big deal audio system so I often sit in the parked truck listening to tunes.

 

Any leads on a circuit like that ? (will have to probe around the fuse box and test I know).
