If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one.

When does the ignition coil start to spark?

The action of switching ON and OFF the primary voltage (ignition coil’s battery power) is referred to as the switching signal. Once the ignition coil gets this switching signal, it starts to spark away and as you’re already aware, this spark gets delivered to the center of the distributor cap by a high tension wire.

What does no spark no start condition mean?

Check that power is reaching the coil packs or ignition coil-on-plug coils. If power is not reaching any of the coil-on-plugs or ignition coil packs, you’ll get a bona-fide ‘no spark no start condition’.

When does a Ford F-150 ignition coil fail?

If it follows the typical Ford pattern, the ignition module will fail first followed by the distributor pickup coil and finally the ignition coil, but the ignition coil usually will last through 2 to 3 ignition modules before it needs replaced. That is the usual pattern, of course there are exceptions. 17 people found this helpful.
