Issue with key symbol appearing on dash since last week, car not starting. Problem started two weeks ago, light came on engine wouldn't turn over, towed to mechanic, four new heat plugs installed. Started that evening, next day same thing, Mechanic said turn key to acc and wait 20 seconds, light on dash goes off car still doesn't start, got jump start and bought new battery, three days later same thing, key light on dash appears and engine won;t turn over. Towed away again yesterday.
