1999 Chevrolet S10, Ignition Photo
Posted to the Waveform Library on 1/26/2006

cause of no start on 99 S10, 4.3 vin X engine. was causing secondary voltage to leak from coil terminal to #4 cylinder, causing no start. still had decent voltage and ignition scope pattern from the coil, so it had me stumped for a while.
