Gauges work, but car doesn’t start
The car won't start, thought he gauges work when the key is turned. I think I need a new battery.
Experienced mechanics share their insights in answering this question :
Hello. If the car does not attempt to start, but the gauges will move, then it is indeed more than likely a battery. It sounds like there is just enough power to cycle the gauges. I would typically start by doing a load test on the battery to see if it passes. If not then it needs to be replaced. If it is fine then the battery cables need to be checked as well as the power to the starter. There is also a common issue with the steering column lock that can cause this. If you need assistance, have a certified mechanic perform these tests for you to determine why your car is not starting.
How to Identify and Fix Common car Problems ?

The most common reasons a Chevrolet Corvette won`t start are a dead battery, an alternator problem, or failed starter.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
The most common reason a Chevy car (or any car) won`t start is a dead battery. If you have a battery tester, check your charge to see if it`s low. A dead battery can also be jumpstarted with jumper cables.
Turn the ignition off on both cars. Connect the positive cable to positive terminals on both batteries. Connect the negative cable to the negative node of the functioning battery. Connect the other end of the negative cable to the ground on the dead battery.
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 ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle`s ignition system, and some of the fuel system`s components.
The cause of this problem is usually one of 3 things – a failed starter motor, a bad connection between the battery and starter motor, or a blown fuse (if present) in line between the starter and the battery.
Connected to the battery is the alternator, which works to generate power for your vehicle`s electrical components. 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.
What if your car won`t jump-start? First, try running the other engine for five more minutes before trying again to start yours. If your car still doesn`t start, you may need a new battery — or it could be a sign of a more serious problem.
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.
Can I Recharge A Dead Car Battery? Often, a “dead car battery” simply means that it`s fully discharged and the voltage is below functional 12V. You can jump-start the dead vehicle and drive it to let the alternator replenish the battery charge. Alternatively, you can attach the dead battery to a battery charger.
The good news is you can jump-start a car with a spare battery. You`ll want to make sure you have a set of jumper cables handy and about 30 minutes to spare after you`ve hooked everything up.
Push and Start
The idea here is to switch the car to neutral and accelerate it along the road by pushing. Once, the car has gained sufficient momentum, engage the second gear and turn on the ignition. This will surely start the engine, and soon the car battery will come to life.
Battery Current Sensor Problems
Dirt and Debris: Dirt, debris, or corrosion on car batteries can penetrate into the sensor causing malfunctioning. This failure can lead to a number of electrical problems including no-start.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down. The ignition system may be the coil, module, or pick up in the distributor.
your car fails to start: the engine`s computer uses the map sensor to gauge atmospheric pressure before the engine is started. a false reading could cause too much or too little fuel to be delivered to the engine. both conditions could keep it from firing up.
When traditional fuses are blown or circuit breakers are tripped, sparks can be generated. However, with ignition-protected fuses and circuit breakers, the risk is greatly reduced. Ignition-protected components are designed to keep sparks from escaping, preventing the ignition of gasoline or propane vapors.
The fuse box under the hood is frequently where you`ll find the ignition relay. It can also be found within the car, in a fuse box under the dashboard.
The source of a “cranks, but no start” problem on your Chevy 350 distributor install is most likely incorrect distributor alignment with the harmonic balancer or a mismatched balancer and timing tab.
The most common reasons a Chevrolet Silverado 2500 HD won`t start are a dead battery, an alternator problem, or failed starter.
A dead battery in your key fob means it can`t broadcast the signal the ignition system is looking for. If your car or truck can`t detect the correct signal, then the ignition will remain locked, and you won`t be able to start your car with the fob in your pocket.
This usually happens because of low batteries, but shock can also cause the fob to lose its pairing. Most remotes can be reset, so check your car`s user manual for the resetting sequence. If resetting fails to solve the problem, the fob will need to be reprogrammed.
The 3X lock system works by pressing the lock button 3X consecutively within 5 seconds from your factory keyless entry key fob. The remote start hardware we integrate with your vehicle understands that receiving a lock command three times is an instruction to start, and it begins the process of starting.

Gas gauge isn’t working. Sometimes the speedometer and the temperature gauge doesn’t work. Limited lights around gauges and radio.
ANSWER : Hi there. The dashboard lights are burned out in the dash and the dimmer switch could be worn causing the lights to be weak. The gauges that seldom fail to work is most likely a loose wire in the dash panel. The fuel gauge that is not going to E when shutting off the car has a damaged rheostat within the sending unit. The sending unit is in the fuel tank attached to the fuel pump. If you need further assistance with your gauges not working, then seek out a professional, such as one from Your Mechanic, to help you.

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.

I have a2006 350Z convertible. The air conditioner doesn’t start until I’ve had the car running for at least 3 miles. I’ve tried t
ANSWER : Depending on how hot it is outside and how hot the interior of your vehicle is, it may take as long as 5 minutes on some vehicles to get the interior cooled down. The hotter it is inside the car the more difficult it will be to cool that space. I would recommend letting all the windows down for the first couple minutes of driving and then try the air conditioner. The cold air may begin coming out much more quickly this way.

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 hesitates when trying to start the car ,but when started then i shut car off and start again it will start right up
ANSWER : Hi there:
Sometimes when you have problems starting an engine initially it is caused by a restriction in fuel flow; caused either by clogged fuel injectors or the throttle body that needs to be cleaned. Once the fuel starts to flow and engine warms up, it’s much easier to start. However, it could also be an air filter, EGR valve or other components that causes this issue as well, which is why it’s best to have a professional mobile mechanic complete a car is hard to start inspection so they can pinpoint the source of this issue.

My car stutter starts, but only after driving it for a few minutes.
ANSWER : Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.
