What causes a Ford F150 to not start?
In this article I’ll show you a very simple, easy and highly accurate way to see if the ignition coil on your 4.9L, 5.0L, 5.8L Ford F150 (or E150, Bronco, Crown Victoria, Grand Marquis, etc) is fried and causing your vehicle to NOT START or not the cause of the problem.
Why does my 1992 Ford F-150 have no spark?
15 people found this helpful. 1992 Ford F-150 5.8L died while driving – replaced ignition coil and ignition module (no luck). there is still no spark. Talked to a mechanic – the signal from the distributor is not being transmitted to the ignition module. Instead of replacing the pickup, I decided to replace the whole distributor. Fingers crossed.
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.
What are the symptoms of a bad ignition coil?

What does no spark no start test mean?
CASE 2: You got NO spark. This test result tells you that something is wrong but doesn’t condemn the ignition coil or the high tension wire as bad just yet. The wire could be bad or the ignition coil could not be receiving its switching signal from the ignition control module or the coil could really be fried.
What causes a car to have no spark?
CASE 2: Spark was NOT present in all of the cylinders A number of things can cause this no spark result. So this what I would suggest: Test the ignition coil . Check for spark directly on the ignition coil tower. The distributor cap and rotor can go bad and not deliver the spark that the ignition coil is delivering to them.

Where does the Spark Go in the ignition coil?
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. From this point, the distributor rotor distributes the spark to the cylinders across the spark plug wires.
