Having problems with your 2001 Buick Regal ?
Have about 135,000 miles-no problems, just tell me how to get theservice engine light off
Try turning the key on and off 5 times @ a steady pace. but without knowing what the ECU fault is it may not reset, best thing to do is get a copy if the Haynes manual, that will tell you how to get the correct fault code and what it means. Even if the battery has been disconnected for to long it will show a fault for 50 key turns.
