Hi
will not start. I have changed start relay. And nothing happens when I press the start button! What more may be wrong and need to be changed??

 

What happens if you put power directly to the starter, does it spin?

Is power reaching the starter when you push the start button?

Is there power coming out of the relay when you push the start button?

Is there power coming into the relay?

Is there power to the "activation" side of the relay when you push the start button?

Does your relay have a good ground?

These would be the first things to check.

Basically you are working your way down the line to see where the problem is. I'd start by putting direct power to the starter. If it spins, then check the wiring back to the relay, then back to the start switch. At each step if it works, then the problem must be further up the line. You will need an inexpensive multi-meter to test these things.

 

Have you checked and cleaned the kill switch?
