Magnetic Pick-Up Assembly

The pick-up coil assembly is located in the distributor. The start pick-up coil supplies a signal to the computer, which will cause the spark plugs to fire at a fixed amount of advance during cranking only. Once the engine begins to run, the run pick-up coil takes over, supplying advance information to the computer. The computer then modifies advance information to reflect other engine operating conditions supplied by the remaining sensors. The 318" V8 engine with electronic fuel injection has only one pick-up coil.
