The starting relay fuse is an important component of how well your car’s engine works, despite the fact that it is not frequently the center of attention in the automotive world. The relay fuse, despite its modest size, makes sure that your engine has the power it needs to start when the ignition key is turned.
Your engine won’t start properly when a starter relay fuse blows, and it may even result in engine stalls or a dead battery. The ideal strategy to guarantee that your car runs properly is to comprehend the functionality and typical starter relay problems.

The starting relay fuse is where?
By vehicle type and model, the start relay’s location varies. The right fender, the instrument panel under the fuse panel, or the fuse box (also known as the power box) are all potential locations. It will typically be in a sizable box with a black top under the hood of your car. Relays and fuses for automobiles are fitted here. It can also be known as a fuse box. Usually, the driver’s side of the car has this box fitted.
The relay receives and discharges wires. However, a lot of other relays in autos look similar. It could be challenging to locate or even remove the fuse box under the dashboard that contains the starting relay. Finding the starting relay that is fastened to the fender wall might not be difficult. The mounting posts and leads on these relays, which are typically cylindrical, can be used to identify them. Please consult your service handbook if you are unsure which relay serves as the beginning relay.
What might stop a Toyota Corolla from starting?
Toyota Corollas have been around for a while and have established themselves as trustworthy, dependable vehicles. Even these vehicles occasionally experience challenges, and starting is one among those issues.
If you consider all of the potential causes of the problem, the majority of Toyota Corolla starting issues may be fixed rather quickly and inexpensively. The issue could be with the starter, alternator, key fob battery, weak battery, corrosion on the terminals, or any number of other issues.
Always start with the simplest solution first since the simplest explanation is typically the accurate one. Since the Toyota includes an inbuilt diagnostics system, one item, an OBD2 scanner, can be very useful.
The OBD2 connector, which is found under the dashboard, is where the scanner is connected. Without starting the engine, carefully connect the wires, and switch the ignition to the auxiliary position.
You will need to enter some data, so be prepared with details like the engine type and car identification number.
How much does a Toyota Corolla starter replacement cost?
Estimated price for replacing a Toyota Corolla starter. Replacement starters for Toyota Corollas typically cost between $312 and $391. Between $60 and $75 is the projected labor cost, while between $252 and $316 is the estimated cost of the parts.
What may prevent a Toyota from starting?
If the starting is spinning and you are getting power, the fuel system may be the source of the issue.
Power Connections
There are numerous electrical connections in your fuel injection system. They are joined at the top, on the cylinder heads, and on the intake airside. Check it whether there is a connection.
Pump and Relay for Fuel
If you have the necessary equipment, test your fuel system under pressure. Check all the electrical connections to the fuel pump with a circuit tester. On by turning the key. If there is a current, the pump is not the problem. Verify the fuse if there is no current. Replace the gasoline pump relay if the fuse is functioning properly. (This article has further information about replacing the fuel pump.)
Engine Filter
The fuel filter could be clogged even if the fuel pump is functioning. Replacing it if it’s clogged should be a part of your maintenance schedule. (This article has further information on gasoline filters.)
You can carry out each of these recommendations in your driveway at home. With the right tools, you can conduct more thorough tests.
- Poor injectors can prevent the engine from starting.
- Starter
- Make sure your starter is bolted down because it can be loose.
- A MAF or ECU
- The computer in your automobile can be broken. You must contact your dealership for help if that is the situation.
- Ring gear or a flywheel
- Your car may not start if these gears have worn teeth. When they are involved, they will shriek.
- Valve for Cold Start
- Your automobile may not start if the cold start valve is damaged and the engine is cold.
While any one of these elements is typically the cause of a car not starting, you can encounter a circumstance where it is outside the purview of these problems. If you have performed all the necessary inspections and the vehicle still won’t start, you might need to speak with your nearby Toyota dealership.

How much does it cost to replace a starter?
I’m sorry to hear that your car is having problems. You should also account for labor charges, which might run from $150 to $1,000. A new starter may cost between $80 and $350.
The average vehicle’s replacement starter costs roughly $500. Your mechanic appears to be charging you the standard rate for this work. However, you should plan an additional $100 to $200 on top of that charge. The mechanic might find other issues, such as a crankshaft or ring gear trouble.
A starter includes the following parts, among others:
- bushes and bearings
- Switch fork
- Solenoid
- either permanent magnets or electromagnetic field coils
- gear for the starter
- Commutator and armature
- Brushes
Remember that you have to totally remove the starter from the engine area. This can result in a hefty labor charge.
The starter is more readily accessible in some cars, and removal takes less than an hour. Some cars are more complicated than others, such those where the starter is hidden beneath the intake manifold. These are substantially slower cars. The complexity of the repair, which is partly decided by your make, model, and year, will determine the final cost.
If you truly believe that your repair bill was overpriced, you can always challenge it.
What occurs when a car’s starter fails?
Similar to the sounds made if you unintentionally start your engine and then hit the starting again, the starter drive gear will frequently make a grinding sound when it is worn out or not engaging properly. The engine flywheel could be harmed if the grinding symptom is ignored.
The starting is where, exactly?
The starter is situated beneath the left mound of cylinders on the driver’s side of a car, between the transmission and the engine. It is kept in place by a few bolts and fastened to the mounting plates. Two cables are also connected to it.
Your car’s engine needs a starter to start and run smoothly. It is a relatively tiny device that is powered by the car’s battery. The car won’t start if a starter is defective.
A starter motor is a dependable component, so replacing one is not something you do frequently. Unlike other components, it might only need to be replaced once during the course of the vehicle’s lifetime.
Nothing happens when I turn the keythere is no click.
When the ignition key is in the “Start” position and nothing happens, the starter motor is not turning the engine over. The most frequent cause of this is a dead battery; for further information, see How to Check the Battery above.
The starter may not crank for a number of reasons even if the battery appears to be in good condition. Here are a few examples:
- At increased mileage, it’s usual for the starter motor or beginning solenoid to malfunction. See additional information on the starter motor. It’s possible that the ignition switch is broken; it’s a typical issue. An electrical switch fitted at the back of the ignition lock mechanism is called an ignition switch. The ignition switch needs to be checked first if jiggling the key in the ignition helps the car start. Watch the video. A faulty connection may exist in the wire controlling the starter solenoid. the existence of a neutral safety switch issue. A fault with a neutral safety switch or the shifter cable may be to blame if a car won’t start with the transmission in Park but starts in Neutral. For illustration, view this video.
I have power, so why won’t my car start?
When a new engine won’t start, the battery is typically at blame. However, a dead battery and an alternator are mostly out of the question if the car is still getting electricity. Some batteries could ship from the factory with a lesser charge retention capacity. This is a manufacturing flaw, and the warranty allows for a replacement.
However, it is simple to believe that the battery is in perfect condition if a car won’t start but still has power. It can be very deceiving, especially if the lights, horn, and other electrical components work well. This is because not all peripherals use the same amount of energy.
To start the engine, however, the starter motor requires a lot of power. It’s possible that a battery nearing the end of its useful life won’t be able to power the starter motor sufficiently. Additionally, some electronic ignition systems start out by using a lot of energy. But since they draw less power from the battery, accessories like lights, horns, and radio systems might function.
Everyone may become confused at this point. So, get your multimeter and examine the battery terminals if your car won’t start but has electricity. It should ideally read 12 volts with the engine off, if not extremely near to it. The battery is on the verge of dying if not.
Start the car, switch on most of the accessories, and read it once more. When you press the accelerator, the voltage shouldn’t drop; instead, it should rise to 13.5 to 14 volts. If this doesn’t happen, there might be a problem with the alternator. When a car won’t start yet has power, this is the most typical problem.
