Sometimes car will randomly not start. When i get in, put the key in the ignition, lights come on, normal, then i turn it all the way to on and wierldly enough the parking brake light comes on, the antitheft light glows red for a sec then returns to flashing, it does nothing. No click no nothing, all the dash lights come on tho. Under the hood u can hear a buzzing sound when the key is turned to the on position, havent really looked for the exact location its coming from. Another thing worth mentioning is, everytime u start it then turn it off it will have a lower and lower rpm level. Will return to its usual 2k rpm start up after an hr of being shut off.
Edit: it's a 2000 ford contour 2.5v6, auto 125k
