I have a 72 240Z and i just recently installed a new ingnition switch. After that i was turning on the car on and off while we where trying to get the car to idle right. It no longer turns on and all i hear is the relay by the passengers side door. Could it be that the relay burnt out and i need a new one or is it a problem

with my starter?

Are you sure you didn't run the battery down?

Yeah, i took it to autozone and they told me it was fine, but ill try a new battery that i have on my other car just to make sure.

Well while i was replacing the terminal cables i noticed that one of the ground cables was not attached to the starter. Now it works. Thanks for the help.
