I have an '07 Mazda 3 that sat for almost a week in sub-freezing temps. Now when we try to start the car, the horn/alarm goes off and cuts the engine off. The engine is turning over so it's not a dead battery. I can't imagine it's a fuel delivery issue since the horn keeps wailing. The remote start works just fine but when we put the key in the ignition and turn it - the same thing happens. Any thoughts?
