Car just out of winter storage. Was running fine. Trying to get the radio to work without success. Went to start the car afterwards and it doesn't. Sputtered a little. Thought it might have gotten flooded so I dried off the plugs without any improvement. OBD system throws the 1251 code which I understand refers to one of the injector groups. What should I look at first, second, and third. It's a cabrio and it's time to drive it finally.
