oil light doesn't come on ?

Hi, I've just changed my battery on my ford fiesta
Style 2007. Now I'm finding the oil light doesn't
Come on when I turn on the ignition.also the engine management light won't go out, until the engine has
Started. Is this a fuse? Help.

Possible oil pressure switch,your engine management light, could have registered a fault and stored it but if it goes out during running may not be too serious, a scan and a look for faults would be the way to go,it may just need deleted.
