Common Causes And Possible Solutions Of Hyundai Santa Fe Won’t Start
Below are the causes of your Hyundai Santa Fe not starting and solutions you can DIY at the garage. For complex issues, consult a qualified mechanic at a fee.
1. Dead Battery, Poor Connections And Corroded Terminals
The car battery provides start-up power to the electrical components that cause the engine to start. If your battery dies, the ignition switch doesn’t get enough power to start the engine. The battery may suffer from loose connections at the terminals, mainly when corrosion occurs.
Corroded terminals reduce current flow affecting the starter powering unit.
Solution
Before replacing or recharging the battery, check the battery voltage to determine whether it is a causative problem or not using the process below.
- Switch off the car and open the hood to access the car battery
- Unscrew the cover casing on the battery to expose the battery
- Remove the plastic/rubber casings on the battery terminals
- Disconnect the wire connections on the terminals
- Connect the terminals of the voltmeter to both battery terminals
- Check the readings on the voltmeter. If the voltmeter reads between 12.4 and 12.7 volts, the battery is in good condition, and you should proceed with further diagnosis.
If the voltage reads below 12.4V, recharge it with a trickle-slow process. For voltage above 12.9, turn on the high beams to remove the excess charge.
For a dead battery, replace the battery with a new battery and use the recommended type and size.
If you confirm that the battery is in good condition, move on to check and tighten any loose connections. Clean the battery terminals to remove any corrosion using a soft brush.
Your vehicle should now start without problems.
2. A Faulty Alternator
An alternator recharges the car battery by converting mechanical energy into electrical energy. A faulty alternator affects the charging system, and the battery dies even if it’s new.
Solution
Replace the faulty alternator with a new alternator and ensure it has similar features as recommended by the manufacturer.
To replace the alternator, follow the following steps.
- Step 1: Turn off the car and disconnect the battery terminals
- Step 2: Locate the cable connections at the back of the alternator and disconnect them carefully
- Step 3: Remove the belt attached to the pulley on the front end of the alternator
- Step 4: Locate and unscrew the bolts and screws holding the alternator
- Step 5: Get the new alternator and replace it and hold it in position using bolts
Replace the belt and tighten it to the required torque, connect the cables and reconnect the car battery’s connection. You can now check the connection by igniting the vehicle.
3. Faulty Electrical Connections Between Battery And Starter
For the starter to operate, it must be supplied with power from the battery. If the connections are loose or damaged by rodents, your vehicle will not start. You, therefore, need to check the wiring connection from the battery to the starter head.
Solution
Repair the broken or damaged parts along the connections. Also, replace any cables and accessories that are destroyed beyond repair.
Insulate the delicate cables and accessories, such as the fuses and joints. Tighten any loose connection or joint that may be losing power.
4. Faulty Starter Or Dead Key Fob Battery
If you check the electrical system and confirm it is in good condition, but your car won’t start, consider inspecting the starter head and the key fob for possible problems.
Check if the starter key is broken or damaged so it fails to complete the electrical circuit. Also, check the key fob battery.
Solution
Replace the damaged starter with a new one that fits the starter groove following the process given below.
- Switch off the vehicle and disconnect the negative and the positive cables from the battery terminals
- Using a screwdriver, unscrew the bolts and clippers holding the starter in position
- Disconnect the cables attached to the starter from the dashboard carefully to avoid damage to the cables
- Remove the starter from the vehicle by pushing it into the dashboard
- Get a new starter and fix it in the groove. Hold it in place using bolts and clippers and ensure its tightly held
- Replace the cable connections into the new starter following the order as indicated in the manual
Also, replace the key fob battery and test if the vehicle will ignite and keep the key fob within range for efficient functionality.
5. Damaged Or Blown Fuse
A fuse may be damaged in cases of excess current in the electrical system, especially if the alternator is faulty. Open the fuse box and inspect the fuses with a testing screw to check for current flow.
Blown fuses are often discolored with a burnt effect due to the excess current. At the same time, the current doesn’t flow through the blown fuses.
Solution
Locate and replace the blown fuses. You can also inspect the electrical connection problem that caused the fuse to blow.
6. Fuel Pump Failure Or Clogged Fuel Filters
A faulty fuel pump reduces the amount of fuel reaching the engine for combustion. In high-demand situations such as heavy loads, the engine fails to start as it requires more energy.
Fuel filters may be clogged by contaminants in the fuel or particles sucked in through leakages. Such contaminants clog the fuel filter and reduce fuel feeding into the engine.
Solution
Replace the fuel pump with an equivalent OEM spare pump and ensure no leakages along the fuel system. Also, replace the clogged fuel filter for efficient fuel supply to the engine.
To replace the fuel pump;
- Start by disconnecting the pump hoses and brake lines connected to the pump
- Unscrew the bolts and nuts holding the pump in place and carefully remove it without damaging attached accessories
- If the fuel pump is in good condition but won’t start, check the fuel filter for any clogged parts
- Open the fuel filter portion by unscrewing the bolts and replacing the fuel filter with a new one. For a completely damaged fuel pump and filter, replace it with the new fuel pump
- Use screws to hold the new pump in position and ensure that the pump is correctly placed
- Connect the hoses and other accessories attached to the fuel pump
- Ignite the vehicle to check if the newly installed pump functions properly
FAQs
Here are a few more additional questions you might be asking now regarding your Hyundai Santa Fe.
Your engine may crank but not start due to low voltage in the battery or a loose connection that supplies little power to the starter but not enough to start the engine.
Check the battery and related connections for a smooth start to your Hyundai Santa Fe.
Replace your car battery after 3-5 years. The battery may be extended for up to 7 years with proper care and maintenance, depending on the usage frequency.
A dead battery has dim or flickering dashboard lights and can be observed when you start the vehicle. In extreme conditions, the vehicle doesn’t start or cranks slowly and goes off.
Conclusion
Hyundai Santa Fe starting problems can easily be rectified if detected early enough. There are many reasons why your Hyundai Santa Fe won’t start, but most of the starting problems are caused by power supply problems or connections in the electrical system.
Ensure proper maintenance and servicing of your car to avoid starting problems. You can safely repair or replace the damaged parts in your garage. However, seek mechanical assistance for complex issues such as engine repairs.
