Where is number 3 coil pack on Lincoln ls v8?

The Lincoln LS V8 (4.6L) has its coil packs arranged differently than many other engines. There isn't a simple "number 3" in a linear arrangement. They're located on top of the engine, but the firing order dictates their placement relative to the cylinders.

To find the coil pack for cylinder #3, you'll need to:

1. Consult a repair manual or a diagram: A wiring diagram or a picture specifically for the 4.6L V8 Lincoln LS engine will show the exact location of each coil pack relative to the cylinders. This is the most reliable method. The Haynes or Chilton manuals are good resources.

2. Trace the wires: If you have access to the engine, you can carefully trace the spark plug wire from cylinder #3. It will connect to the coil pack that fires that cylinder. Caution: Only do this when the engine is completely off and cooled down.

Without a diagram specific to the year and engine code of your Lincoln LS, giving a precise location is impossible. The coil pack arrangement can be subtle and vary slightly between model years.
