My car will not start! Drove my 09 SC580 Sunday for a short ride about town with my boy and parked her in the garage as usual when finished- ran just fine. Monday drove truck to work so on Tuesday am I was excited to drive her to work. Just one problem- She won't start. cranks and cranks but no go. It has gas and has never had any problems before so very disappointed. What am I missing? what would cause the car to be able to crank but not to catch? Security system? seems to be in park OK, belts seem to be fine- nothing looks out of place- Help needed in Maryland!
