If it is just the lights staying on check the door switches. Faulty door switches are common problems on all fords. If the car did not start I am not sure what that problem is. Could be anything. Check to make sure the battery is charged and that the starter is getting power from the battery. If the battery is good and there is no power going to the starter solenoid then something in the ignition switch circuit is preventing the starter solenoid from engaging. |
