lntermittent starting

[Nismo]

I had the exact problems you are experiencing when I first had my Corolla. Sometimes, it starts on the button and other times it didn't. Also, when I drove my car and then stopped and tried to start the car again, it was like dead. I had to wait until the car cooled down and then it started up again. It was so frustrating.

The problem lies down to contacts wearing out on the power feed to the solenoid.

I followed the guide by SQ Engineering by installing a 4 pin relay. This has overcame the problem and I never had that problem since.
