Re: 1985 150v V6 no spark on all cils
Losing spark on ALL cyl's is often a fault in the ignition switch or a pulled lanyard.
On the motor, disconnect the black wire with a thin yellow trace that connects the ignition boxes to the wiring harness, retest for spark.
If you now have spark then the problem isnot with the motor/ignition system, but in the ignition switch/lanyard.
If you start the motor it will NOT shut off.
