Experienced mechanics share their insights in answering this question :

Hi there, thanks for writing in.

If your 2010 HHR is having problems not cranking, but you just replaced the battery, then it’s highly likely that you have a broken starter or damaged electrical relay somewhere. When the vehicle shuts off all of the sudden as you indicated, it’s typically caused by an electrical malfunction; most of the time in the ignition system.

The best way to know for certain where the problem exists is to contact one of our professional mechanics to complete a no start inspection at the convenience of your home. This will allow them to pinpoint any electrical or mechanical problems you’re having so they can complete the right service repairs.

When you have a brand-new battery but still can`t start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail. Flickering gauges and a burning rubber smell could indicate that the alternator overheated and requires replacement.

Why won`t my car start but the battery is good? If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.

Bad Spark Plugs

If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.

Bad starter motor: If you hear a single click when you turn the key, but the engine won`t start, that could mean there`s a problem with the electrical system. The starter motor is responsible for physically turning the engine over and getting the engine to fire. If this is the issue, you`ll need a new one installed.

Bad Spark Plug Or Broken Distributor Cap/Rotor

If you have a good battery and enough fuel in the gas tank and your car still won`t start, chances are you have a bad spark plug. Why? A bad spark plug will prevent fuel ignition, and the vehicle won`t move.

The new battery does not have to be configured for the most current car models. Banner conclusion: No registration required; a check of the electrical functions after changing the battery is recommended.

The battery can be fully charged but still not be able to start the vehicle if it is failing or has a dead cell. Other likely issues are the fuel pump, ignition switch, battery cables, starter, or a clogged fuel filter.

Put simply, your alternator keeps your car battery charged, allowing you to turn on your car and use electronic accessories such as your headlights and radio. If you`re experiencing car alternator problems, you may find that your car won`t start or stay on for more than a few minutes.

The ECU will eventually relearn its ideal settings and reprogram itself with use.

Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.

One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn`t, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.

Turning your key in the ignition triggers the starting system by sending power from the battery to the starter solenoid. The starter solenoid then activates the starter motor, which spins the engine a few times to turn it on.

If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.

The car wasn`t driven long enough for the battery to recharge fully. The vehicle charging system has a problem, like a bad alternator or voltage regulator. An electrical system was left on, draining the battery. The battery is too old and just can`t hold a charge.

With a cranking system, symptoms are divided into one of three possible troubleshooting categories: Click — No-Crank (solenoid clicks but starter doesn`t crank) No-Click — No-Crank (solenoid doesn`t click/starter doesn`t crank) Slow Crank (starter cranks, but engine RPM slow to start vehicle)

Starter motors should make noise when you turn your ignition key fully to activate your car. If you turn the key and do not hear anything, there`s a chance that there`s something wrong with the vehicle`s ignition switch.

If rusting is the issue, you can bypass the bad starter solenoid wire. To do so, use a 12V wire to directly provide current from the car`s battery to the point where the starter and solenoid connect. You`ll hear a click sound indicating that the connection is made. Now turn on your ignition system.

Symptoms of a burnt out diode:

The engine will begin to run rough, lack power and eventually stall and not start again. The battery warning light will turn on, warning you that there is a problem with your alternator charging system. The headlights will become dim due to reduced battery voltage.

If the alternator`s fuse or fusible link is blown, the alternator will not be able to charge the battery. The battery then doesn`t store enough power for starting the car or keeping it running.

Touch the positive lead of the multimeter to the “86” terminal. Touch the negative lead of the multimeter to the “85” terminal. The multimeter should read 0 ohms. If it does not, the starter relay is bad and needs to be replaced.

The easiest way to perform an ECU reset is by removing the fuse from the fuse box. It is a very simple process, and all you have to do is pull out the car key, remove the fuse from the fuse box, and then put it back after about 15 to 20 seconds. Doing this clears any long-term memory stored in the car`s ECU.

With the proper updates, reprogramming your engine control unit/engine control module (ECU/ECM) can improve your vehicle`s all-around performance, resolve engine issues, and optimize the vehicle for your specific needs.

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.

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.

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.

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.

Installed new battery but car won’t start – 2005 Honda Civic

ANSWER : Your symptoms could be caused by several components. At first, it sounds like the starter is cranking, but isn’t powerful enough to turn over the engine. This could be due to a bad electrical connection or faulty starter. Replacing the starter is the only option at that point. Now if the engine is turning over, and still unable to start, you have an issue with fuel, air, or spark delivery. Turn the key to accessory and listen for the faint sound of your fuel pump priming. It will sound like a very quiet winding or whirling. That will let you know if the fuel pump is powered and trying to work. You should also check the spark plug and wires. There are specific tools you can use to test them. However, if your spark plugs have over 50,000 miles, they may need to be replaced anyway. If you still need help with a diagnosis, a certified professional from YourMechanic can come to your car’s location to inspect the no-start and pinpoint the correct repair.

New battery, car still won’t start. Single click sounds, like a dead battery

ANSWER : It sounds like you may have a faulty starter solenoid. If you hear a clicking sound when turning the key, it is likely that your starter solenoid may be faulty. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. As electricity is supplied to the starter a small gear comes out and engages the flywheel to spin the engine over as you turn the key. 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 recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

Car won’t start with new battery

ANSWER : This may be related to many different possibilities, some of which may be related to a lack of spark and some of which may be related to a fuel delivery problem or a combination of both. For example, if the ignition coils, crankshaft position sensor, spark plugs, spark plug wires or ignition module are faulty, this may cause the motor to not produce the spark needed to ignite the fuel in the motor.

In the case of a fuel delivery problem, this may be related to low fuel pressure, faulty or dirty fuel injectors, a faulty or dirty idle air control valve (this relays information about air intake to the computer which makes fuel adjustments), or potentially a faulty fuel pressure regulator or fuel pump. Fuel delivery problems will typically not allow the proper amount of fuel to be delivered to the cylinders which results in a lean fuel condition which can cause backfiring or simply cause the motor not to start as a result of fuel starvation. I would recommend having an expert from YourMechanic come to your location to diagnose your no start problem.
