What parts do you need for an ignition relay replacement for your Mazda? How much do they cost?
There are three broad categories of ignition systems:
- Conventional (or “contact breaker” or “breaker point”) ignition system
- Electronic ignition system
- Distributorless ignition system
Ignition control modules have been gradually phased out, but they’re still found in many vehicles from the early 2000s.
Here are the major parts of the electronic ignition system and what they do:
- Theignition switch($5-$2,800) completes the circuit and fires up the engine when you turn the key or push the ignition switch. Hitting the ignition switch again will interrupt the electrical system and shut down the engine. Like a failing ignition relay, a bad ignition switch can prevent your car from starting.
- The ignition relay ($6-$105), or starter relay or starter solenoid, is the component that physically completes the circuit when it receives the signal from the ignition switch. It’s a small plastic box with several metal prongs.
- Thecar battery($90-$700) supplies the ignition coils with a low-voltage current once the circuit is completed.
- Ignition coils($15-$910) transform the 12-volt current of the car battery into 60-120,000 volts of raw power.
- Ignition cables, or spark plug wires, ($4-$805) pass the voltage created by the ignition coils and timed by the distributor caps to the spark plugs.
- Spark plugs($2-$65) shoot a high-voltage bolt of power across a small gap in each of your vehicle engine’s cylinders, igniting the mixture of air and fuel inside at just the right time. These electrical explosions bring your car’s engine to life like a mechanical Frankenstein.
Some popular brands for ignition relay parts include Bosch, Denso and ACDelco, which you can purchase from local parts stores such as AutoZone and NAPA Auto Parts, or from online retailers such as Amazon and Summit Racing.
Keep in mind You might require a new ignition relay, switch, or coil to complete repairs to your vehicle’s ignition system.
Where can I buy parts for an ignition relay replacement?
Some popular brands for ignition relay parts include Bosch, Denso and ACDelco, which you can purchase from local parts stores such as AutoZone and NAPA Auto Parts, or from online retailers such as Amazon and Summit Racing.
If you prefer OEM parts, you can also try your vehicle manufacturer’s official website. Honda, Ford, MAKE, and just about every other car maker sells OEM parts online. Check your owner’s manual for specifications so you don’t buy the wrong part.
Should I buy an OEM or aftermarket ignition relay?
Original equipment manufacturer (OEM) parts cost much more than aftermarket parts but often include better warranties. For example, if a certified Toyota mechanic installs a genuine ignition relay in your car, you’ll get a 24-month/25,000-mile warranty. The average cost of parts is even higher for luxury makes like Audi or Mercedes-Benz.
That said, some aftermarket performance parts manufacturers offer equal or higher quality parts.
Where can I get my Mazda's ignition relay replaced?
Deciding on a local repair shop often feels like making a big decision on too little information. Are the prices fair? Are the mechanics trustworthy?

How will a mechanic replace my Mazda's ignition relay?
A Mazda ignition relay replacement requires confidence in dealing with car electronics, particularly the ignition system. Don’t underestimate the risk and complexity involved in working with batteries; our explanations are pretty simplified.
Here’s what the pros will do:
- Test the starter relay by connecting a multimeter to a car battery terminal and measuring the current
- Disconnect the car battery cables
- Remove the mounting screws, cables, and wires of the old external relay and remove it from the fender or firewall
- OR remove the cables, motor housing, wires, and bolts securing the internal relay to the starter motor
- Install the new ignition relay, either external or internal, and replace the mounting equipment
- Test the car’s ignition system
What will a bad ignition relay do?
Because an ignition relay is crucial to maintaining a complete ignition circuit, a bad ignition relay in your Mazda can cause a host of ignition, engine, and power issues. Neglecting a fix could mean:
- Your car has starting problems
- The starter could get stuck ON, causing the starter motor (which kicks the engine awake and then is supposed to shut off) to stay on and wear out
- The ignition relay keeps drawing from the car battery and runs it down
More importantly, a failing starter relay could cause a sudden loss of power in the engine. Seek a fix immediately before your safety is threatened.
What is an ignition relay replacement?
An ignition relay replacement targets the electronic component that activates your vehicle’s ignition system. Faulty relays can affect your car battery’s lifespan and engine efficiency. Since relays can’t be repaired, the old starter relay must be replaced with a new one.
What are the symptoms of a bad ignition relay?
The most common symptoms of a bad ignition relay are related to power, engine efficiency, and starting your car. Among other issues, you might notice:
- A whining noise: The starter motor is supposed to shut off when the main engine wakes up, but if the starter relay is stuck closed, the motor won’t take a break.
- Clicking noises: A damaged relay struggling to complete the ignition circuit will produce a clicking noise as the current sparks and sputters.
- Your car battery is low: If you have to jump-start your car in the mornings, it could be because the starter relay is stuck in the ON position and draining amps overnight.
- Your car won’t start or starts inconsistently: A completely failed ignition relay will leave you without the means to close the ignition system circuit and start your car.
- Your engine stalls: The ignition system doesn’t just start the car but also controls the ignition of fuel in the engine cylinders. A faulty relay could cut off the electrical spark that fires the engine, causing a sudden loss of power.
If you notice that your vehicle is making odd noises, experiencing starting issues, or suffering sudden power losses, you might need to replace the ignition relay.
How often do you have to replace your Mazda's ignition relay?
The ignition relay is intended to last the life of your car, but heat, vibration, and power surges (or shorts) can shorten its lifespan. Often, a bad starter relay can be the fault of another failed piece. For example, if the relay is knocked slightly out of place, the small gap will cause electricity to continuously arc and melt the plastic.
Can I replace a starter relay myself?
A starter replay replacement is a moderately challenging DIY job that requires only basic equipment but demands some familiarity with electronics and your vehicle’s ignition system.
Depending on your vehicle model, you could have an internal or external ignition relay, which changes the installation location. Whatever you do, don’t work on your car’s ignition without disconnecting the battery first.
FAQs
Will my car start with a bad relay?
Your car probably won’t start with a bad relay. A failed relay that’s burnt out or stuck in the OFF position can’t complete the circuit that kickstarts the engine. If it does start and you hear a clicking sound, that’s probably a faulty relay failing to maintain a consistent connection.
Can a bad relay drain your battery?
Yes, a bad ignition relay can drain your battery. Just like your headlights, if the relay gets stuck in the ON position, it’ll continue to siphon energy even if you turn off your car. Consider buying a new relay if you find your replacement car battery doesn’t last as long as it should.
What causes an ignition relay to fail?
A failing ignition relay could be the result of excess heat, a power surge, improper alignment, or vibration. The failure of one of your car’s electrical components can often result in problems for the others. For example, if oil leaks from the car engine into the alternator, it could cause a short that fries the relay. Or if the fuse box is loose, the relay might get damaged knocking against other car parts.
