Why does my 2004 Hyundai Sonata not start?
2004 sonata cranks, won’t… On Sunday the 16th, while driving on a highway, the car simply shut off. I was able to safely pull over, tried re-starting the vehicle, etc to no avail. My brother later towed it to his house where we began our research. Fuses that we checked looked good. Fuel pump turns on to prime the system when the key is turned on.

Why does my car have a no spark light?
In this case you most likely have a failed ignition coil. That would explain why you have injector pulse and no spark. If the light does not flash, you still have a problem with both injector pulse and spark, suspect a problem with the ECM (engine control module).
Why does my car have no fuel injector pulse?
I bet if you connected a test light to a fuel injector wiring connector while trying to start, you would find that you have no fuel injector pulse either. This is because the crankshaft position sensor gives the signal for both fuel and spark, and it is very common for this sensor to fail on this vehicle.

Why is the fuel pump relay not turning on?
The ECM controls the fuel pump relay and this relay will only energize when commanded on. Does the check engine light come on; if not, then the ECM is not turning on. Do all the other combination meter warning lights come on?
What should I do if there is no power in my fuel pump?
A test of the battery with a digital tester that provides current voltage, cold cranking amps, and state of health should be done first. The battery is the heart of the electrical system and if it stumbles or fails, it can affect all other systems.
Why is my fuel pump going so slow?
Slow crank, battery and connecters good. It is unlikely that an oil leak would have any impact on the slow cranking you describe. Generally, slow cranking is related to a weak battery or charging system. It sounds like you may have a weak battery, a failing…

Why does my Hyundai Sonata make a clicking noise?
If your Hyundai Sonata won’t start and make some clicking noises, this indicates a drained battery. Sometimes your battery might have enough charge to make the clicking noise, but this charge depletes immediately after the starter requests some electrical current. Hyundai Sonata won’t start, but the battery is good
What should the voltage of a Hyundai Sonata battery be?
The voltage of the battery on your Hyundai Sonata can be measured precisely with a multimeter. Before the test, the multimeter is set to the voltage range of the battery and connected to its plus and minus poles. Successful testing of the car battery, i.e. checking the voltage, usually results in values of approx. 12 to 13 volts.
What’s the average life of a Hyundai Sonata starter?
A starter is a motor for starting the engine of your Sonata. The average life of a starter motor is about 100,000 to 150,000 miles, and the life will be shortened if the engine is started more frequently.

Why does my Sonata make a clicking sound?
Symptom: When you turn the key to start the engine of your Sonata, you will hear a clicking sound, which is the sound of a bad starter motor. And if the starter motor does not work with a healthy battery, suspect a malfunction of the starter. If the starter fails, it usually needs to be replaced with a new one.
