What would make the blinker relay click when the key is on and you push the start.
Last year I had some finicky starts where the starter solenoid would click. I replaced the battery. This year it would not start at all. I tested the solenoid and felt that was the problem and replaced it. There was no change. The blinker relay clicks. My next step would be to test the starter but the blinker relay click must mean something
