Recently acquired my mother's 1993 Volvo 240 wagon. Mom always kept it in her garage and put very little mileage on it. We've had it less than week. It drove great on the 100 mile trip to our home & the next day while running errands. No garage available here. It's been parked in our driveway and over the last week, we've had heavy rains and a few nights in a row of below freezing temperatures. Now, we're unable to get the car to start. Sounds like its firing on 2 cylinders but quickly sputters out and won't crank with subsequent attempts. Recharged battery on a warmer 48 degree day today with same results. Any help appreciated.
