Car won’t start, I think it’s the battery but I’m not sure.

Last night I tried to start my car but it wouldn't turnover. I assumed it was the battery so I called a friend for a jumpstart.
He accidentally switched the red and the black cables when he put them on my battery and his car died, so we called another friend and he put it on correctly but the car still wouldn't start.
It makes a series of clicking noises when you try to start it and the radio and the inside lights flicker but they don't stay on.
We checked the relay and it was fine, and we don't think there's anything wrong with the starter because it makes a series of cl
Experienced mechanics share their insights in answering this question :
The clicking noise you hear is either a sign of a battery that is too weak to turn the motor over or a starter solenoid that is faulty. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key. I would suggest having a professional from YourMechanic come to your home to diagnose your starter.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

It might be a battery or alternator problem.

If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!

Broken Starter: If you`ve put your key in the ignition and hear a clicking noise when trying to turn the key then your starter has likely gone bad. Clogged Fuel Filter: If everything else in your vehicle feels fine but you`ve found yourself with trouble starting the car, you might have a clogged fuel filter.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
If you hear a whine or the sound goes fuzzy when you hit the gas, your alternator is probably failing. If the vehicle won`t crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
Single click

A single loud click when starting (even after trying to jump-start your battery) is usually caused by a faulty starter motor, starter relay/solenoid or other electrical problem.

The most common reasons a Kia Soul won`t start are a dead battery, an alternator problem, or failed starter.
A 2013 Kia Soul ticking noise may be caused by low oil or possibly caused by one of the recall issues from the manufacturer. Ticking is a common symptom of very low oil levels in a car. If you hear ticking while driving, you should add more oil as soon as possible. Even better, schedule a complete oil change.
There is a wide variety of possible causes for the clicking sound when driving your car. However, the most common of them all are faulty CV joints, loose wheel nuts, bad struts, loose drive belts, low engine oil, faulty battery, inadequately inflated tires, etc.
A clicking noise when driving can indicate problems with your car`s oil, battery, CV joints, or brake pads. If you notice a clicking noise while driving, check your engine oil. If your oil is not low or dirty, you may be dealing with a problem with the car`s battery, starter, axles, or brakes.
Can you jump-start a car with a bad starter? Most of the time, NO, you can`t jumpstart a car with a bad starter unless you repair it. When the battery is dead, jumper wires or boosters are employed. You use a second battery to provide the necessary electricity to start the car.
Set your battery tester to cranking test mode, then start the vehicle. Your tester will record the lowest voltage that the battery is able to maintain while the starter motor is working. Make note of your battery`s cranking reading. Healthy batteries should maintain between nine and 10 volts during cranking.
Can a Bad Starter Drain Your Battery? So can a bad starter drain your battery? The short answer is: Yes, it can. It could also drain the battery even faster if you repeatedly try to start your car with a faulty starter.
If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. This growling or whining sound happens when the belt that turns the alternator`s pulley becomes misaligned or rubs against the side of the pulley.
It requires a good deal of energy to crank the car`s motor, and if a battery is not replenishing its power properly due to a faulty alternator, it will become drained and ineffective. You will hear a clicking noise while attempting to start the car, and the engine will have difficulty turning over.
There are a number of reasons why your car might be slow to start but runs as-normal once it gets going. Causes can vary from weather conditions to battery health, wiring issues, starter motor concerns and fuel-pump health.
Your car`s ignition switch, alternator, battery, starter, or a fuse could be malfunctioning. Your safety switch could be broken. This switch keeps your transmission from starting unless you`re in park or neutral. If it is malfunctioning, it will keep your car from starting.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Water was spilled in the trunk which soaked the car battery. Car won’t start now. Does water destroy a car battery?
ANSWER : Hi, thanks for writing in about the concern with the BMW 320i. If the battery was submerged in water then it’s completely possible for the battery to short out and die. Your friend will need to have the battery replaced. Also be sure to get all of the water out of the trunk. Have a certified technician, like one from YourMechanic, help you guys out if you need assistance with replacing the battery. Good luck.

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.

2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.

The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.

New battery & fuel pump. Hours later car starts and shuts down 3X in a row. Finally it starts, 48 hours later, won’t start at all
ANSWER : Checking all the fuses was a good move. I would also want to put a scan tool on it and check for diagnostic trouble codes (DTCs) as well as seeing the data that the computer is seeing.

A fuel pressure test would be a good idea to verify correct pressure and so that you’d be able to eliminate that possibility. It should be 58psi on your Magnum.

I also recommend getting your battery tested (I know, it’s new, have it tested anyway) and be sure it’s charged to at least 75%. And yes, loose battery cable connections can result in electrical problems.

If you need some assistance with this, consider enlisting a certified mechanic who can perform the checks I’ve mentioned and diagnose your starting issue firsthand. The mechanic can then perform the necessary repairs once the problem has been isolated. Good luck.

Car didn’t start this morning, do I need a new battery or did I drain my battery? (although I can’t seem to think of how I did?)
ANSWER : Hi there!

First off, don’t worry about being a new car owner – everybody has gone through this same situation at least one time in their lives. When the radio or other accessories are turned on while the engine is not running, the power is drained from the battery. If it’s too long, it can cause the battery to prematurely wear out. However, since your vehicle is a 2010, it’s possible that the battery was on it’s last legs as it was. Usually when the car starts, the alternator charges the battery. But if the battery is worn out or old; it usually means the battery needs to be replaced. We have several professional mechanics from YourMechanic.com who can complete the battery installation for you.

Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.

At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.

Car won’t start 2002 Toyota Camry
ANSWER : Hello – your symptoms are a bit confusing. The "starts, but shuts off rather quickly" behavior could be a security system problem with your key. The stalling when slowing or stopped could be dirty throttle body, malfunctioning idle air control valve, or other fuel supply issues. I recommend a hard starting inspection to get to the bottom of this, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
