Wont Start
Went Dead overnight. Tried to get a jump the next morning, nothing. Bought a brand new battery, engine cranks but does not start. All fuses and relays APPEAR to be good but I dont have the necessary tools to check for power.
My car has 139548 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Make sure the battery cables are clean and tight. You need to make sure you check ALL fuses to see if there are any that are draining the battery. Crank your car for 15 seconds. Do this 3 times. Check for any diagnostic trouble codes. A compatible scan tool can operate the auto shutdown (ASD) relay to verify its operation. And lastly, be sure you have fuel!
If your still having problems or would like help having this inspected, a technician from YourMechanic can come to your car’s location to diagnose your starting issue and perform any repairs to get you back on the road.

The most common reasons a Dodge Magnum won`t start are a dead battery, an alternator problem, or failed starter.
Blown Fuse
If there has been a surge, a fuse that controls the fuel pump, the fuel injectors, or another component that`s vital for your car`s functioning, it may be the cause of your car`s failure to start. Unlike most of the other problems, this is one that you can check yourself, if you want.
Starting relay position
The fuse box (also called the power box), the instrument panel under the fuse panel, or the right fender are all possible locations. In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box.

Car not starting: Another symptom of a faulty ignition relay is a no power condition. If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition.
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.
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the “OK to start” signal.
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.
Broken or Damaged Ignition
If your headlights can turn on, but your car won`t crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.
A blown fuse signals a short circuit. This occurs when an electrical component draws a stronger current than it is designed to handle due to the device malfunctioning.
A broken fuse won`t allow current to pass. This will create a potential difference across the terminals of the fuse. At one terminal, battery voltage is present and at the other terminal, no voltage is read.
Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead.
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.
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.
Common reasons for this to happen:
An issue with the mass airflow sensor may manifest itself when a car starts and then stalls soon after starting. Fuel Pump Relay: The fuel pump relay functions much like a fuse for an electric fuel pump. The fuel pump relay engages as the vehicle is started and starts the fuel pump.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

Car won’t start – 2004 Ford Focus
ANSWER : Hi and thanks for contacting YourMechanic. Check the battery cables for more corrosion and clean them up again. You may need to put backing soda and water mixture on the terminals to clean the corrosion completely off. Make sure that the cables are tight and also tight on the starter solenoid. By rocking the vehicle back and forth and using the clutch to start the vehicle, this is an indication that the cable on the starter is either corroded or loose. If you need further assistance troubleshooting your starting system, then seek out a technician, such as one from YourMechanic, to diagnose and resolve the issue.

Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.

Wont start (Click), shift gear from P to R then back to P Starts it, after runs for a while it starts up fine.
ANSWER : Your vehicle has something called a neutral safety switch that will prevent the vehicle from starting when it is in any gear position other than park or neutral. Occasionally, this switch can malfunction causing the car to stall as soon as you put it into any gear. This switch usually also monitors gear selection data as well to transmit back to the computer. This switch is connected to the starter solenoid which allows it to complete the starter circuit only when the transmission is in park or neutral. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

I put a penny in place of a fuse, tried to start my car and now it wont start and makes a grinding sound when i try to start it
ANSWER : Hi there. Putting a penny in place of a fuse, not recommended, replace with the correct fuse. The fuse is there, to protect the circuit. If the fuse blows, there is a short to ground. The grinding sound, when you try to start your vehicle, could be the starter. The starter drive could be at fault or the flywheel has a problem. I recommend having your vehicle’s no start be diagnosed and repaired by a certified technician from YourMechanic.

Why does my car struggle to start every 4th to 5th time?
ANSWER : It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.
