My car won’t crank or turn over to try to start. Maybe the Infiniti immobilizer security system.
Could Infiniti immobilizer security system not letting the car start.
My car has 167000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
To see if the Immobilizer System is not working properly or is active, check the security light on your vehicle. If the light is flashing fast, then the system is active. You can reset the system by removing the battery cables for about 2 minutes and clearing the computer out. If the system wants to stay active and not reset, then the Immobilizer System controller will need to be replaced. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

The most common reasons an INFINITI G35 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.
Car Clicks But Wont Start
Check your batterys cables and connections. Vibrations from the road may have loosened the battery clamps, leading to poor electrical contact. You may also find that there is a lot of corrosive buildup around the battery terminals. This can also limit the electrical output of the battery.
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.
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.
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.
Symptoms Of A Failing Alternator
Hard starting or stalling engine: An underpowered battery (because the alternator isn`t charging) will have trouble starting the car. Dim or too-bright lights: A damaged alternator may deliver either too little or too much power to the headlights.
The most common reasons a Nissan 350Z won`t start are a dead battery, an alternator problem, or failed starter.

Car won’t crank when it’s cold and now won’t start at all
ANSWER : Hi there:
Usually this issue is cased by low cranking amps inside the battery. If you’ve recently had the battery replaced, it’s possible that an electrical component that makes up the charging system might be damaged or faulty. It’s also quite possible that the main electrical relay or the starter relay is giving you fits. To know for certain what the exact issue might be on your 1989 Toyota Camry, you should have a professional mobile mechanic complete a car is hard to start inspection, so they can pinpoint the source of your issues and recommend the right repairs.
When I go to crank my car the key stays in the start position and the car is constantly trying to crank itself.
ANSWER : First, let’s make sure about some terminology before I proceed. I will assume the motor is actually turning over. If the car is trying to start, the motor has to be turning over or it is not trying to start. This is an important distinction when diagnosing the starting system. As a technician, I go to different parts of the system based on this description.
If the key is stuck in the start position, this is a ignition lock cylinder issue and the reason the starter continues to turn the motor over. If the starter is turning but the motor is not, then the starter is likely the problem. Either that or the teeth on the flex plate are all gone. This would require removing the transmission to repair.
If the car runs intermittently, this can be a big challenge. And it also means the starting system is working. It will need to be diagnosed when it is failing. A working car cannot be diagnosed because there is nothing wrong. Where you park your car should not have any affect. It certainly could be a wiring problem. Wiring problems hide really well and can happen anywhere in the miles of wires that are in your car. Isolating the system that is failing is really important here. At the moment I am unsure which system is failing. Starter system, ignition lock cylinder and or ignition switch electrical or something with the engine control system.
When the car is failing, you need to check for spark and fuel pressure. If neither is present, this is a clue. Usually the crank sensor will do this. Does your car have a tachometer? If so, does it move at all when cranking. This is a clue whether or not the cam and or crank sensor is working. Is there a Check Engine Light on with the key on? If there is a Check Engine Light, the code or codes can be used for specific diagnosis.
All of these concerns will send you down a diagnostic path. Be sure not to confuse yourself by misinterpreting multiple system failures. If the key does stick in the start position, this would be the first problem to solve. After that, does the motor actually turn when the starter turns? After that, the question of "Why won’t it start?" is first answered by finding what the motor is lacking. Fuel, spark etc… Good luck.
If you need assistance with these checks, contact a certified mechanic who has the tools and experience needed to properly diagnose this starting issue with your car.
Car won’t turn over. No lights come on when I turn it. Can’t even lock my doorsvor push the seat up or back.
ANSWER : Your probably correct, it sounds as though your battery is done. But it also sounds like you have charging system issues. I’m not sure that fixing your battery and charging system will solve the problem with the car shutting off, but it’s possible that it will and it’s a darned good place to start. By contacting Your Mechanic, you can have a technician come to your home or office to check out your car and help you figure out what to do next.
Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.
If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
The car crank but won’t start
ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.
What do I do when the car won’t crank and shows ‘check starting system’? But after a couple of trials it starts without any issues
ANSWER : Hello. The first thing to understand is that the check starting system light illuminates for several reasons. The starting light will give you a diagnostic troubleshooting code when the vehicle is scanned with the light on. Due to the fact the car eventually started without any issues, its likely the actual starter and battery (main components) are working just fine. Your issue is probably a bad connection or a fuse. One of the fuses is located under the drivers fuse box under the dash. Check the diagram on the panel for the exact fuse number. Also make sure the connections are all secure. There are some electrical tests that you can perform, but you need to replicated the no start situation before we can do that. If you seek professional help, it will be the exact same situation, and this can lead to hours of diagnostic work and hefty bill. Unfortunately this means the you will want to wait until the vehicle wont start, and then test for available voltage at the starter.
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.
