The other day I went to turn the car off and upon turning the key to lock, the starter began working. So, I thought that the ignition switch went bad. I bought a new one and had it replaced. This didn't help however. Also, I've noticed some sound that is similar to an electrical relay that keeps turning on and off every several seconds. It's coming from below the dashboard, in the lower passenger's side. This occurs constantly, both when the ignition is on and off, as well as when the car runs. This keeps draining the battery so I now disconnect the battery terminal to prevent this. The car is idling rough, sounding as if it has no power to remain on when I apply the gas pedal. I had the spark plugs replaced along with the fuel filter, wires, rotor, air filter and distributor cap as well. I checked the coil and it's fine. What might be causing this and how to fix it?
Hello. It sounds like the starter relay might be bad and is causing the starter to stay on, which is the clicking noise that you are hearing. There could also be a problem with the starter solenoid. The problem you are experiencing with the rough idle could be solved by adjusting the air/fuel mixture. Another possibility is that the distributor is going bad or the timing needs to be advanced to improve the idle. I would suggest that you have the electrical system and ignition system inspected by a certified technician, such as one from YourMechanic.
