Got a problem with my S2. Getting no spark from the coil. Have changed coil, leads,plugs,dizzy cap,rotor arm,battery. Seems like the green wire on the neg side of the coil is'nt doin what it's suppose to correct me if i'm wrong but it should go live with the ignition and then pulse when the engine has started. Mine goes live but no pulse. Please help before i sell it and go back to VAUXHALLS
