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.

Nissan started Monday morning around 6:30am when we moved it to get another car out of the driveway. I went out to start it to go to an appointment later that day at 1pm and it wouldn't start. It didnt tuen over, it didnt do anything, the battery light came on and I assumed the battery was dead. Jump started it later Monday afternoon. It started and ran but wouldn't start back up a second time. Jump started it tonight (tuesday), let it run, then took it for a 15-20 min drive, get home turn it off, attempt to start it again and it won't turn over. The dash lights come on and the gau

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.

If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can`t hold a charge when the alternator is shut off.
The most common reasons a Nissan Xterra won`t start are a dead battery, an alternator problem, or failed starter.
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.
Your car`s ignition switch, alternator, battery, starter, or a fuse could be malfunctioning. Your safety switch could be broken. This switch keeps your transmission from starting unless you`re in park or neutral. If it is malfunctioning, it will keep your car from starting.
The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

It is possible in some cases to jumpstart a vehicle that has a faulty alternator, as long as the battery has enough of a charge to keep running. However, the alternator should be replaced as soon as possible.
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.

Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
Starting Your Nissan

If your vehicle has a key fob port, insert the fob in the port and tap the brake pedal or clutch while pressing the START/STOP button. If your vehicle does not have a port, you`ll need to step on the brake or clutch while pressing the key fob up against the START/STOP button.

drains faster in cold weather, so it`s possible that your car battery is losing power in colder weather and is unable to start your car in the morning as a result. This is even more likely if your car battery is old or exceptionally corroded. In these cases, replacing your battery is your best course of action.

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 started with a jump start earlier today, but won’t start now despite turning over.
ANSWER : It’s possible that when you jump started the car the first time that an electrical relay may have been damaged. This is a very rare situation, but has been known to happen on some GM products like your Chevrolet Avalanche. It’s also possible that an ignition system component like the crankshaft position sensor or relay may also be faulty which wouldn’t be related to the battery. The best thing for you to do is have a mobile mechanic come to your home and complete a car is hard to start inspection, so they can pinpoint the source of your truck’s issues.

Car won’t start even after a jump. Things turn on, engine cranks but won’t start.
ANSWER : The problem sounds like the battery is too low to crank the engine and was most likely caused by the alternator not charging. You should have battery fully charged for at least 15 minutes and then see if it cranks over. You may need to replace battery and alternator. Have the system checked and replace these components as needed.

So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.

Every 3-4 months, my car won’t start. It does turn over though.
ANSWER : If your battery is weak or has bad connections to the battery, then you may have problems starting the vehicle intermittently. This is due to low voltage to the starter which is taking all the power, while the electronic ignition and the electric fuel pump get cut short. This will cause the vehicle not to start.

You may think the vehicle is turning over okay, but the starter is taking in all of the power just to turn over the motor. You should get the battery and it’s cables checked, as well as the charging system, for any problems by a qualified mechanic so they can diagnose the problem and do any repairs needed to prevent this problem in the future.

ANSWER : Hello – your clutch hydraulics are the problem here. Check the clutch hydraulics fluid level – and it may share the same reservoir as the brake master cylinder (both use brake fluid as the hydraulic medium). If fluid needs to be added, that means that probably the clutch slave cylinder is leaking – this might be visible as a clear, but bitter-smelling liquid on the ground under the engine. I recommend a clutch hydraulics inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : Hello – most likely, your hard starting is caused by a malfunctioning fuel pressure check valve, or fuel pressure regulator. The fuel system is supposed to hold a small amount of residual pressure in the system for faster starts. A leaking check valve makes the fuel pump work harder, and run longer when cranking, before adequate fuel pressure is available for the injectors. I recommend a hard starting inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs. The " engine continues to crank after I release the key" is actually normal on most new cars now. Turning the ignition key to the "Start" position, even momentarily- then releasing it, initiates a "start sequence", which is computer-controlled, and runs the starter for a few seconds on its own. This is a precursor feature for the "auto stop/start" feature (at stoplights) more and more cars have now. Nothing to worry about.
