I picked up a 90 EF hatch for my sister in law and it seems that it has the symptoms of the main relay. I read online and the car will not start sometimes when the car sits in th sun. I bought the car from a guy that drove it to and from work back in May right as it was getting warm. I have changed the wires/plugs and oil as well. My sister in law has had the car for almost a month and today it did not want to start twice. She normally leaves the car parked under the garage port, however today was the first time the car was left out in the sun in these temperatures as well. Anybody changed one on an EF? From what I have read it is a pain. May just have to take it to a shop. HELP.
