I have a 2008 saab 9-3 2.0 Turbo. Here lately I've had several starting issues. First I got a stability control light and the car wouldn't even turn over. Still have the stability issue but now the car will turn over with the ignition in the on position not the start position. When I turn the key off there's a few things under the hood that seem to stay powered up. Not aure if this is a computer prob or what, plz help.
