Ford 2.3 Spark Plugs Diagram

April 27, 2011 Updated: December 04, 2021 By: Abraham Torres-Arredondo Clause ID: 115

In this article I'll show you a very simple, easy and extremely accurate way to see if the lighting 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 Non START or not the cause of the problem.

The test you'll be doing is an on car test through with the ignition coil in activeness. You won't need any expensive examination equipment to surveil the simple step-by-step examination instructions presented here. You'll need a sparkle tester, a multimeter, a 12 volt test light, and a helper (to assist you in cranking the locomotive engine).

If you're looking for the resistance test of the primary and secondary circuits, this article will non help you (in my opinion, the primary/secondary resistance prove is a complete waste of time and life that does not work around 99% of the time to name a bad ignition coil).

You can happen this instructor in Spanish here: Cómo Probar La Bobina De Encendido (Gerald Rudolph Ford 4.9L, 5.0L, 5.8L) (at: autotecnico-online.com).

Important Suggestions

Lean on 1: The ignition coil test, I'm gonna show you here, is done with the engine cranking and thusly you've got be careful and stay alert. Take all necessary guard precautions.

TIP 2: You'll deman a helper to service you crank the engine. I paint a picture that you keep him or her outside the vehicle till you motive him (or her) to crank the engine. Your helper should persist foreign the vehicle and away from the ignition switch before and after you settled up the mental testing.

Topple 3: The inflammation coil is not the only thing that can causal agent a cranks but does not start condition, when it fails. Other components can fail and provoke a none-start.

If you have already replaced the ignition coil Beaver State the tests in this tutorial show that it's good, the following teacher English hawthorn be of help:

1. How To Troubleshoot A No Start (Ford 4.9L, 5.0L, 5.8L).

Symptoms Of A Stale Ignition Coil

This Crataegus laevigata seem like a no more brainer because the most obvious symptom of a bad ignition coil is a No-start no-spark condition, but here are a few other symptoms you'll see along with no spark:

1. No of the trigger plugs will fire spark.
2. The fuel pump will soundless work.
3. The PCM will still activate the fuel injectors.

The one thing to think of, if you do get wind that the ignition ringlet failed, is that the locomotive engine volition be flooded with gasolene and this May require that you remove the gasoline fouled spark plugs to dry them out (Beaver State your vehicle may calm down not start).

Nowadays, and in case you'rhenium wondering, finding out if the want of spark is caused by a bad ignition coil or a bad ignition control module is not hard. It's something that you can do without removing these parts (to replace them and get word which peerless solves the no light-no-beginning problem) and therein instructor I'll show you how.

How Does The Inflammation Scroll Bring?

Although the following account is not hypothesis heavy operating theater full of monolithic technical run-in/terms, it will help you to see how the kindling ringlet whole caboodle.

Knowing a little pragmatical working theory wish answer a lot of questions that the article doesn't answer.

It all starts when you turn the key and bug out cranking the engine and in a nutshell, this is what happens:

1. The ignition controller module (ICM) and the ignition coil get superpowe (12 Volts).
   1. Power is supplied to the ignition coil thru' the wire labeled with the number 2.
2. The visibility ignition cartridge (PIP) sensor, which is what Ford calls the crank sensor, gets power from the ICM and as the engine cranks it starts to generate a crankshaft posture signal (called the PIP signal).
3. This PIP signal is and so sent to and received by the ignition ascendency module (ICM).
4. When the ICM gets the PIP signal, information technology starts to switch the ignition coil ON and Polish off by interrupting the ignition coil's primary voltage.
   1. What this means in plain English is that the ignition system module interrupts the ignition coil's battery power ON and so Away. How? By closing and then orifice the Ground circuit this kindling coil's battery power needs to flummox to Ground.
   2. The action of switching ON and OFF the primary voltage (inflammation coil's battery power) is referred to A the switching point.
5. Once the ignition coil gets this switching signal, it starts to spark gone and as you'rhenium already aware, this spark gets delivered to the center of the allocator cap by a richly tension cable.
6. From this power point, the distributor rotor distributes the spark to the cylinders crossways the spark stopple wires.
7. By this time, the fuel injection system computer is also injecting fuel into the engine, which the spark will ignite, thus the engine starts!

In the next page we'll jump far into the first ignition coil test.
