My EFI Relay starts to click on and off when I take my key out of the ignition. I noticed it about 2 months ago, I restarted the car and turned it off immediately and the clicking stopped. It did not start doing it again until 1 month ago. Now it does it every time. I have to leave my key in the ignition or the relay will start clicking and won't stop and my battery will die. I replaced the relay with a new relay on 2 occasions, it did not help. Can anyone give me some idea what this might be. Could it be the ignition ? PLEASE HELP
