2012 nissan Altima and it won’t start but battery is good, Do you know which fuse I need to replace for the car to start again?
I tried to start my car it won't start but battery is good. I believe its a fuse. Do you know which fuse I need to replace for the car to start again?
My car has 90000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
If the engine is cranking relatively rapidly, then the battery is probably OK, but strictly speaking the only way to tell if a battery is really "good" is to perform a load test. There are many fuses (not to mention fusible links and relays) that can prevent a car from starting but no "one" of these many components is any more likely to fail than another. I would start by checking to see if there are any stored diagnostic trouble codes. Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the immobilizer system is on, you may see a security warning light. If the warning light is on, to temporarily override the immobilizer system, see these instructions. If you are in a situation where there is no starter motor operation at all with the key held in the "start" position, the procedure is to test for power AND voltage drops to the starter motor/solenoid. If there is no power, or a large voltage drop is measured, then the electrical circuit supplying the starter motor has a fault. The circuit that will have to be tested begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch, neutral start switch, and terminations. Basically, with a fully charged battery, and with the key held in the "start" position, the starter is either getting power or it isn’t. With the key in the "start" position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. Note that starters can and sometimes do develop intermittent faults due to bad spots on the armature. If you want the foregoing diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a no start diagnostic and the responding certified mechanic will get this taken care of for you.
In another scenario, if the engine cranks at adequate RPM, be sure there is adequate fuel in the fuel tank and that the fuel is not old. As above, download any OBD-II trouble codes that have been stored and examine those codes for diagnostic clues. Check for adequate fuel pressure, injector operation, and a spark at the spark plugs. Basically, if the starter motor is turning the engine over rapidly, at sufficient RPM, but the engine does not catch and run, that means that there is an ignition, fuel, air induction, or mechanical fault in the engine that will have to be repaired. Check for vacuum leaks, an air induction fault like a stuck idle air control valve or, considering fuel, check for a failed temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start. Other possible no start faults are low compression, defective spark plugs, a defective coil(s), a failed crankshaft or camshaft position sensor, a failed throttle position sensor, and a broken timing belt. Regardless of the underlying cause, if you request a no start diagnostic the responding certified mechanic will get the problem diagnosed and repaired for you promptly.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most common reasons a Nissan Altima 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.
The main fuse box is located under the hood. Open the hood and locate the fuse box. Open the fuse box cover (press the tabs and lift it up). Pull the fuses one by one (or check the schematic) and check them.
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.
Possible causes of a power failure could be either bad battery connections, a bad ignition switch, or a bad alternator. What you need to do is check your vehicle`s power sources.
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.
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 you`ve replaced your battery but the engine still won`t start, it could actually be an engine problem. A seized engine won`t turn over, and that often resembles a bad starter or dead battery. If you suspect that your problem stems from an engine issue, it could take hours to diagnose and repair.
The most common causes of no-start conditions are the battery, starter, battery cable, ignition switch, or the fuel pump. Any of these can be intermittent issues, which will not always act up. Given that you have had success with shaking the battery cables, this may indicate that one of the cables is failing.
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
If your Nissan car, truck, or SUV has a key fob port, just put the fob in the port and tap the brake pedal or clutch as you press the START/STOP button. If your Nissan doesn`t have a port, just step on the brake or clutch as you press the key fob against the START/STOP button.
It might be a battery or alternator problem.
A rapid clicking noise when trying to start your car could mean there`s something wrong within the electrical system. Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly.
If your car won`t start but the lights come on, it is likely not an issue with your battery so it`s time to turn your attention to your ignition switch. A failed ignition switch won`t be able to supply power to the starter motor, ignition system, and other engine controls, preventing the engine from starting.

A failed ignition switch won`t be able to supply power to the starter motor, ignition system, and other engine controls, preventing the engine from starting.
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won`t start.
The PCM on a car is the power control module. It is the computerized central processing unit of your vehicle`s system. It oversees the two main components of the powertrain (transmission and engine) and several other car components.
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.
If you are having trouble starting your car or getting the engine to turn over, the air-fuel mixture might be off balance. All vehicles are very sensitive to proper air-fuel mixture and may have difficulty starting if it is thrown off by a bad mass air flow sensor.
Fortunately (spoiler alert) the root cause of a no-crank is almost always simple. Most of the time it`s simply due to a low or dead battery, or voltage drop through a corroded connection. Rule those out before you suspect the starter itself.
It might be a battery or alternator problem.
A rapid clicking noise when trying to start your car could mean there`s something wrong within the electrical system. Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly.
Electrical devices or lights left on, a faulty charging system or alternator, and severe weather are the most common causes of a dead car battery, but maybe it`s just time to get a new battery.

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.
Car not starting, replaced battery and alternator fuse but now inside fuses are blowing and still not starting
ANSWER : Hi there. It is quite possible that you have an exposed electrical wire or a short somewhere in the electrical system that is the root source of your starting issue. A fuse or relay will continue to break when the circuit is unable to complete. This is typically due to a wire that is pinched, frayed or a ground wire connection that is faulty. Due to the multiple possible sources of this problem, I would recommend having one of our experienced mobile mechanics come to your location to complete an electrical problems inspection, so they can determine the root source of this issue and recommend the right repairs.
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 blows ecm run/start fuse after starting and then dies replaced fuse and repeats
ANSWER : Hi there. Typically when this issue occurs, damage will be instant – meaning if it’s going to damage the ECU, replacing the fuses would not help start the vehicle. So, at first glance, I would assume the ECU is OK. What is more likely is that you have an exposed wire somewhere that is causing the fuses to pop. Trying to diagnose these issues can be tricky sometimes, so it might be a good idea to have a professional mechanic complete an electrical problems inspection to isolate why you’re having these issues and recommend the right repairs.
Jumper cables crossed.The car wouldn’t start. Found it was a fuse that blew which we replaced. The car turned on but then we had t
ANSWER : If you are very lucky, you may just need a battery. When you cross the jumper cables, you can do a lot of damage in the blink of an eye. If it just trashes the alternator and the battery, you have beaten the odds. You could try disconnecting the battery to see if it still goes dead. If it does, you may just need a battery. If it doesn’t go dead when disconnected, then you have a draw in the system. In your case, you might have damaged one or more diodes in one of the many control units that inhabit your car. Testing for an off key draw is time consuming and requires a pretty thorough knowledge of the car’s systems. You can have this thing checked out by a pro by contacting Your Mechanic. They can send a technician to your home or office to check out your battery drain and advise you as to the next step.
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.
