A constant buzz would be notification the coolant is low. The sensor is in the middle of the top of the radiator. Buller connector. Hold the bullet to a chassis gnd and if the buzz stops.............that was the problem. Low on water. Drives you nuts.

Starter Cut relay is only on the cars with Theft Protection. Other cars have the Blue jumper connector in it's place.

 

he probably means the relay under the dash for the fuel pump.

 

min has theft protection...a while back i made some posts about my car alarm randomly going off...havnt heard it since.
