FMS88 is a true mechanic ~ what he said is perfect & what I said is rather screwball ballpark ~ (the Ignition Module black plastic thing with two screws named Pickup in the photo AND Signal Rotor in the photo <---- the space you need to adjust is between the two of these parts and is the Air Gap 0.30" in the photo not 0.15" like my guess) Clear as MUD but think of it as adjusting the points gap in older school distributors...

Use something like a digital multi meter or 12v light probe to ensure voltage at every point where there should be voltage ~ the ignition switch on my truck was worn out and played some not so cool tricks while driving down the road A.K.A. why did the engine stop & why did somebody slam on the brakes YIKES..? Freaking worn out contacts in the ignition switch...

Enjoy the Fix
