Customer Question

i have an 07 chevy tahoe 5.3L, when i try to start it i hear a loud clicking coming from under the hood. I open the hood and feel the throttle body and that is where the noise is coming from, also the powertrain relay in the underhood fuse box is clicking. When this happens i can't start the car. It got worse to the point where i can not even start the car anymore. The dash is displaying engine power reduced, service stabilitrack. Check engine light is on with PO606 code.
