It did keep running, just once though.
I've got a scan tool but it's the bare minimum. It has thrown a code for EVAP P0449 but I can't really see how that's related.
Nothing obviously wrong at the BCM, everything is clean and no scorching or anything crazy like that. Still just starting simple and disconnecting the battery for an hour or so, the internet says that it should reset.
It can't hurt, at least.
