99 Forester

Just got this car and left the lights on and now the car won't start ( turn over). I found the button on the left side and have tried turning the key to the on position and then hitting the button. But still the car won't turn over. it does lash the check engine light and it sounds as if some relays are actuating in the engine compartment.

Need help??

I found the wire to the solenoid and fallen off. This is resolved.
