Your Ignition coil only has on B+ connection . The (-) side goes to the Powertrain Control Module (PCM) which in turn is controlled by the distributor pickup plate.
OK that i know what i mean is that there is no volt going thru the wire when i turn the ignition switch to on. I want to know why, All the fueses are ok. THANKS
