I have a problem with my fuel pump not switching off when turning the engine off. Sometimes it switches off as usual, sometimes it will continue to hiss and whir away for a couple of minutes and sometimes it will carry on overnight without me realising !
Trouble is it seems to be killing my battery as it didn't have enough juice to even power the clock inside the car this morning. I'm also not sure if this will waste fuel at all ?
Baz suggested to me that it could be shorting out a while back, but I honestly don't know where to start with that part of the loom.
