Details about the Ford 4.6 V8 Ignition System
The Ford 4.6 V8 has coil-on-plug ignition, which means that the PCM controls spark plug ignition. This eliminates the need to know the engine’s firing order. It was critical to ensure that the spark plug wires were connected into the correct cylinder on older engines that used distributors with spark plug wires. Misfires or non-starts could occur if you did not connect the correct wire to the correct plug.
The spark plug ignition sequence is electrically controlled in the 4.6 V8. The PCM in the Ford 4.6 uses crankshaft position sensor readings to optimally ignite each spark plug independently. This is more efficient in terms of emissions and performance. It also means that the firing order of the engine is more consistent and regulated.
While the Ford 4.6 V8 does not have spark plug wires like older engines, it does have eight electrical plugs that power the spark plugs. Each of the eight cylinders is represented by one of these plugs. While it is more difficult to misalign these plugs, it is nevertheless critical that they go to the correct location.
