In order for me to provide you with pictures, Diagnostic procedures and electrical schematics to find and fix your problem since this board does not allow sending pictures.

PLEASE include your original question(s) and the MAKE-MODEL-YEAR and ENGINE SIZE of your vehicle when you contact me.

PLEASE tell me if you do your own repairs and or your skill level of auto repair. This is VERY VERY important if I am to be able to help you repair your own vehicle .
