I have searched for a good answer but can't seem to find anything.

My IS300 was working fine with absolutely no issues until I messed around with the aftermarket amp in the trunk. After I reconnected the amp, I went to start the car so I can move it. It didn't start. It didn't turn over. It didn't crank. I didn't even hear the click of the starter. It does nothing. I'm suspecting the starter relay, but not sure.

The battery is fine. I had it checked out and its good. I have checked all the connectors and everything is secure. I checked the fuses for the starter on the inside of the car and they were fine.

When I turn the key to on there is a buzzing sound. It buzzes for a couple of seconds and then has three short buzzing taps.

Thanks for your help!

 

i could be completely off on this but im thinking maybe positive current on the frame somewhere related to the aftermarket amp, like i said i could be way off on that so dont throw things at me if i am, just tryin to throw out ideas lol

 

I'm going to check that.

Thanks!


Any other ideas would be greatly appreciated

 

Got it started. I disconnected the amp connection at the battery. Still no start. I pulled out the starter relay fuse and then put it back in and then it started right up.
