Need car diagnosed.

My car won't start. I need someone to tell me what is wrong and fix it.
Experienced mechanics share their insights in answering this question :
It sounds like it cranks but won’t start up, this usually has to do with the three basic requirements for a running engine that is compression fuel and spark at the right time. That being said I would have a certified mechanic come out and test for fuel pressure spark these are the more likely causes of a no start condition. If your car wont crank at all thats an entirely different problem, if it wont take a jump either I would start looking into the starting circuit including the starter itself. Have a mechanic come and inspect your car for a proper diagnosis.

The most common reasons a Honda Accord won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Clicking noises are usually synonymous with the battery or the alternator, so if you don`t hear them, your Honda Accord may not start due to a starter issue. A starter is a small electrical motor that gets your engine started. When it`s broken, your engine flywheel won`t crank, and your car won`t start.
The starter system warning light should go out shortly after engine ignition. If it remains on, or comes on while driving, there is a problem with the starter system. As a temporary measure, press and hold the ENGINE START/STOP button for up to 15 seconds, while pressing the brake pedal to manually start the engine.
If the “Check Charge System” light turns on in your Honda Accord, take the vehicle to a mechanic as soon as possible. This light indicates a fault with the charging system, which could cause your vehicle to lose power suddenly.
It could be a minor glitch in the battery terminals, a dead battery, a defective ignition switch and so on. Car starting problems are mainly related to the battery, car self-start system or fuel lines. Below are some of the common reasons why your car is not starting upon switching on the ignition.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
You hear a single click

Usually, this points to a faulty relay or solenoid, or a bad or jammed starter motor. Solution: Rock your car back and forth or tap the starter motor with a hammer and try starting the engine again. If this works, you are good to go!

If there is no sound when you turn the key, but the lights and accessories work, it could be the stater relay or starter solenoid. However if there is no sound at all, not even a click, it`s probably your battery.
Front Sensor Camera The camera is located behind the rearview mirror. The radar sensor is at the lower part of the front bumper.
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.
One possibility is the solenoid. A single “click” sound comes from the engine compartment or from under the car. This could mean that the solenoid is trying to engage but that the internal components are stuck and unable to work properly. Repeated “clicking” sounds usually indicate a dead battery.
The clicking you hear is likely the starter solenoid not getting enough power because of a dead battery. If the car shut down while driving, that is usually an indicator that the alternator is not charging the system.
One of the first and most common symptoms is simply no response from the starter when you turn the key – no noises or engine cranking at all. Sometimes, repeatedly trying the ignition can produce a result, but that`s not guaranteed. It usually means there`s a faulty connection in the solenoid.
Use a circuit tester to see if the current is getting to the solenoid. Place one lead of the circuit tester (test lamp) to the feed terminal of the solenoid. Attach the other lead to bare bodywork metal. If the tester lights up, then the problem is with the solenoid or the starter itself, not the current getting to it.
To check the voltage reaching the starter, connect the voltmeter to the starter feed terminal and earth it on the starter casing. Test the voltage reaching the starter. For a negative-earth system on a car with a pre-engaged starter, connect the positive lead of the voltmeter to the feed terminal on the solenoid.
A weak or dead 12v battery is most likely the cause of your Accord not cranking or cranking very slowly. Ensure the battery in your vehicle is in good condition. A battery with 12.5 volts should be used. Alternatively, you can jumpstart it if you don`t have a voltmeter.

IGNITION SWITCH TURNS ON BUT ENGINE WILL NOT CRANK

No warning lights or other signs of electrical activity could indicate a dead battery or that the battery cables are loose or corroded. Try turning on the headlights. No lights? Then you have a battery or battery connection problem.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Got a diagnostic, mech says car need theromostat and all coils and plugs. Car was fine then check engine light 2009 Mini Cooper
ANSWER : Hi – I would do a quick check on the problem codes causing the Check Engine light and other warnings you mention. In general you would have an occasional misfire or hiccup that you should feel as engine vibration as any of the 4 coils start to go weak. Some engine ignition systems are more sensitive to coil compatibility than others, and replacing all of them at once with higher mileage is a good guideline. However, you don’t have all that many miles on your Mini. I would challenge the reason to replace all of them on this occasion. I recommend a thermostat replacement and misfire inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose and/or correct these problems, and give you an accurate assessment of other damage and cost estimate for repairs.

I need to know the tempature difference inside a car (car turned off and windows are up) and outside a car during the summer
ANSWER : Hi, thanks for your question. I’d be happy to provide my insight. You may notice as much as a 40 or 50 degree (Fahrenheit) increase from the inside and outside the car in the summer. You can try and put an oven thermometer in the car and see how hot your car gets. This is why the AC takes a while to cool the inside of the car. The color of the car and interior color and material will also make a difference on how hot it gets. Here is also an article by us on how to quickly cool down a car on a hot day. Hope this helps and best of luck!

My check engine light came on and my car was diagnosed as needing a catalytic converter. Now, my car won’t start.
ANSWER : Hello, thank you for writing in. The catalytic converter can cause a vehicle not to start. This would be an extreme situation where part of the catalyst inside has broken off and is clogging the entire exhaust pipe. Tap on the catalytic converter just hard enough to loosen anything that may be logged in. You do not want to do any more damage. Now if the vehicle is not cranking (as in the starter is not turning) then your issue is not related to the catalytic converter. If you already know this is an issue, start by replacing it first and take further diagnosis from there. For more diagnostic help, or to have the catalytic converter replaced, contact our service department to schedule an appointment.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.

ANSWER : Hi there. It is quite possible that the starting issue you’re currently having with your Ford Focus is not related to the starter replacement. However, it could be due to might be due to your battery problem. When your battery does not have enough power to engage the starter, it also impacts other important systems critical to maintaining ignition, ranging from the ignition coils to fuel system components. It might be a good idea to have a professional mobile mechanic from our team come to your location to compete a car starts then dies inspection, so they can correctly diagnose this issue and ensure the right repairs are made.

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.
