My car is not starting.
Battery died completely so I replaced it with a new one. While I was driving all the power went out and the steering wheel got stiff. So I assumed it was the alternator because it drained the battery. So I switched out the alternator and now the dash and lights outside and inside work but not the power windows or locks work. Also when I push the brake so I can push the start engine button and nothing . The brake doesn't go down and the light doesn't turn green
Experienced mechanics share their insights in answering this question :
It is possible there may be a loose connection somewhere that is not allowing the power to flow properly. Often this can be caused by a loose ground fastener or a broken battery cable connection. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of the vehicle to run some tests and offer a more personal diagnosis of your no start condition.
How to Identify and Fix Common car Problems ?

The most common reasons a Lexus IS250 won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons a Lexus ES350 won`t start are a dead battery, an alternator problem, or failed starter.
The most likely reason your Lexus is not starting after you change the battery is that the security/immobilizer / anti-theft feature disabled the engine start.
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.
While your battery may be at fault, there are other reasons that your car can have power but not start. For example, if your car has a manual transmission, it may have a safety switch on the clutch and the clutch must be depressed for the vehicle to start.
The cranking continues, but the usual sound of the engine roaring to life doesn`t happen. If this happens to you, chances are it`s not the starter. Instead, it`s likely because your engine isn`t getting at least one of the four major components it needs to start: fuel, air, spark, or compression.
Door Panels Melting
This is another common problem, though much less common than the dashboard melting. At the core though, the IS 250 interior plastics just don`t hold up very well the to heat in some climates, particularly anywhere that`s known for having more serious heat, especially in the summer.
It might be a battery or alternator problem
Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly. If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered.

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.
Map sensor car won’t start up good ?
Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.
At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.
car hesitates when trying to start the car ,but when started then i shut car off and start again it will start right up
Sometimes when you have problems starting an engine initially it is caused by a restriction in fuel flow; caused either by clogged fuel injectors or the throttle body that needs to be cleaned. Once the fuel starts to flow and engine warms up, it’s much easier to start. However, it could also be an air filter, EGR valve or other components that causes this issue as well, which is why it’s best to have a professional mobile mechanic complete a car is hard to start inspection so they can pinpoint the source of this issue.

If you recently replaced your battery, the issue may be caused by a malfunctioning alternator or other electrical component that comprises the charging system on your Nissan Sentra. The best way to find out which item specifically is faulty, is to have a professional mobile mechanic complete a car is hard to start inspection. This will allow the mechanic to determine the precise source of what’s going on with your Sentra and recommend or complete the right repairs.
My car stutter starts, but only after driving it for a few minutes.
Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.
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…
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
My car will be starting perfect and when the gas tank gets lower it will start having problems .
Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.
Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
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.
