NOTE: It is a fix better left with an experienced mechanic, because replacing an ignition module can be very dangerous.
Has your vehicle started to sputter, stall, or be challenging to start? Have you ever tried each of the usual fixes: checking battery, checking the fuel line, adding a gas additive to rule out water in the fuel tank, and ensuring the spark plugs aren’t fouled?
Should your vehicle is actually an around-town car, do you have tried running it in the freeway for a time, just to blow out any carbon build-up in the engine? Any one of these things can cause a reduction in the starting and overall performance of your vehicle.
Maybe your ignition module should be replaced if you’ve considered all of these possibilities and had no luck. In case you aren’t knowledgeable about the ignition module, it is the intermediary device that, once you turn the true secret, transfers a signal from a sensor in the distributor to the ignition coil, which in turn makes the spark plugs fire. The ignition module could be inside the distributor itself, on the outside in the distributor, or inside the compartment. Some modules also adjust timing.
Once this component needs replacement, you’ll have many different symptoms to inform you that it’s time. Unfortunately, many of these symptoms are the same regarding other engine or component problems, so you might need to do a bit of your own automotive analysis to pinpoint this concern.
Before You Change the Ignition Module
Because the part (and the labor) at a mechanic’s shop can be so expensive, it is a great do-it-yourself project. The project involved is straightforward, relatively easy, and quick. It can save you a bundle of income on the markup for the part and all of the funds for the mechanic’s labor, by doing it yourself.
Saving money and expanding your automotive repair skill set are good things; however, for this job it’s important? specifically if you are with limited funds? that you are certain that the module is indeed the issue before you put money into the replacement module at the auto parts store. But if it turns out to never be the problem, in most cases a car parts supplier will allow a buyer to return an electrical part which has been opened.
Acquiring a Clear Diagnosis
You must test the ignition module, before beginning. There are a number of testing tools on the market to accomplish this. These tools are fairly expensive and therefore are not something you will grab often, however. This tool might not be the very best investment to your growing variety of tools if you’re not really a professional mechanic.
You can instead have the ignition module tested at an automotive repair shop. Once you have a correct diagnosis of a failing module, you can perform the replacement yourself.
If the mechanic informs you that there is a problem related to the module, but it is not the module itself, you will possibly not need a new part. Ask the mechanic to explain in detail the type of the malfunction and what the repair will entail.
When the vehicle’s issue is being the effect of a short within the ignition system due to contamination or buildup of salt or dirt on the surrounding areas, it might make better sense to have that issue repaired. It will probably be cheaper than changing the ignition module yourself.
Depending on the sort of electrical short, you might even replace the ignition module yourself, only to find that it doesn’t repair the trouble. Discuss almost every other issues outside a sure-thing failed ignition module together with your mechanic.
Parts and Tools You’ll Need
As a way to change your vehicle’s ignition module, Here’s a list of the parts and tools you’ll need:
Electronic testing unit for the ignition module, except if you have already gotten a definite diagnosis at a shop.
The service manual for the vehicle brand name.
Screwdrivers for the type of screws used to contain the module set up.
Pliers, wrenches, and any other tools required
Supply of shop rags.
Good overhead lighting.
Locating the Ignition Module
Consult the service manual to find out the exact location of the module. Most service manuals will have the schematic for the engine and will point you right to it, though because the ignition module is located within the distributor area, that’s the first place to begin looking.
Changing the Ignition Module
Follow these steps to modify your vehicle’s ignition module:
Disconnect the vehicle’s battery cables.
Using the diagrams in the service manual, locate the ignition module.
Disconnect the wires and remove the screws, ensuring that they are held in a safe place.
Remove any auxiliary components to reach the ignition module.
Remove any screws and wires connected to the ignition module and take away the old module from its housing.
Replace with all the new module, inserting it exactly as the existing one was placed.
Reattach any wires and screws leading to the ignition module, ensuring that none of the wires are loose, pinched, twisted and bent or showing signs of cracked insulation. Repair or replace any that appear to be damaged
Replace any other parts you needed to remove to reach the ignition module, also checking and repairing or replacing any worn wires.
Close any covers, replace any housing units, and make sure no wires are caught beyond any covers in the ignition module compartment.
Reconnect battery cable.
Close the hood, and check the ignition. The vehicle should start right up.
