Re: 2001 Chevy caviler still fires yellow replaced coils...
No fuel ! Spray carburetor cleaner into the engine through the throttle body . SECURITY light lit ? Injectors firing ? Just replacing parts isn't the way , you have to test . If there is spark , yellow or not it's fuel related . Or engine crank , cam timing off . Some good videos on youtube .
