Car won’t crank when it’s cold and now won’t start at all
About 2 months ago outta no where my car was trying to die and I noticed it was only when I had the ac on? Any time I had ac on and turned car off,tge next time I'd go to drive it..it wouldn't crank for first few tries(sometimes took 15min if trying) then I noticed when it's cold outside,my carvwont crank but when it heats up outside the car cranks..if it's cold out,and I go out to crank car every few hours the car starts..I drove my car Friday pm,and forgot to go crank it so when I went to leave sat pm,it wouldn't crank(which is normal)so I figured it'd start sun once

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.

There are a few reasons why your Toyota Camry won`t start
If your Toyota Camry isn`t starting, then there are a few things you can check first. According to VEHQ, the top five reasons could be a dead battery, a defective alternator, a broken ignition switch, a clogged fuel filter, or an empty gas tank.
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.
Cold temperatures affect the chemical process inside the battery and reduce its ability to hold a charge. It also thickens engine oil, increasing friction in the starter motor and forcing it to work harder. Your alternator belt is also prone to cracking in extremely cold conditions.
Most commonly, its caused by a fuel pump that`s not working. The fuel pump fuse may have blown, or the fuel pump itself will need to be replaced. Alternatively, this problem could be caused by a leak in the fuel lines, clogged fuel injectors or a bad fuel pressure regulator.
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.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. Spark plugs typically need to be replaced every season or 25 hours of use. You should also check that the spark plug gap is set properly.
Fuel Pressure & Fuel Pump
When the fuel pump starts to go bad, that pressure will start to go away when the engine isn`t running. This is one of the most common reasons that your car won`t start after it`s sat for many hours.
In fact, when the temperature is below 32 degrees, car batteries lose 35% of their strength, and at zero degrees they lose 60%. If you`re not prepared, you may find yourself stranded on the side of the road with a dead battery and an expensive tow in your future.
Can a bad spark plug cause a car not to start? Yes. The spark plug ignites the fuel/air mixture inside the cylinder. If the fuel doesn`t burn, the engine doesn`t make power.
Your engine won`t start. While the cause could be a range of issues related to fuel, compression, or spark, the fuel pump is often a likely culprit.
If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
Car starters can fail for several reasons, and age isn`t usually as critical a factor as overheating. Engine mechanical problems can overload the starter motor, leading to overheating. Oil leaks can cause overheating because the starter can`t cool off.
If your car won`t start, but your battery is fine, chances are you have a bad alternator. This is another charging system issue, like a dead battery, that won`t let you start your car.
A dead battery is the most common reason why engines fail to start up. A common reason for batteries to fail is drain. Your car`s battery typically expends a small portion of its storage to start your car up, and then recharges from your alternator as you move.
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.
What`s the problem? Car batteries produce less electrical current when it`s cold, due to the chemical reaction being slower than on a warm day. Cold batteries simply don`t produce the same amount of power as warm batteries, and this effect can lead to starting issues.
Why does the cold drain battery power? Most batteries work through an electrochemical reaction, which sends power signals to your terminal ends. This chemical reaction slows down in colder weather, weakening your battery`s power.
Faulty wiring or a blown fuse could be causing an issue within the electrical system. Finding an electrical issue can be pretty tricky and dangerous, so leave it to the experts to figure it out. If your electrical system is in working order, it could be the fuel system that`s keeping the car from starting.
Engine won`t crank. If the electrical contacts inside the switch have failed, turning the key to crank the engine might not result in any response at all. Engine starts and stalls.
Turn the ignition off on both cars. Connect the positive cable to positive terminals on both batteries. Connect the negative cable to the negative node of the functioning battery. Connect the other end of the negative cable to the ground on the dead battery.
There are a few things that can cause the crankshaft position sensor to fail, including damage, debris and faulty circuitry. Even for modern electronics, the engine is a violent and destructive environment. Though built for this, most sensors eventually succumb to the ever-present heat and vibrations of the engine.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.

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.

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.

Map sensor car won’t start up good ?
ANSWER : 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.

My car isn’t starting, it’s really cold out. I was wondering how can I start it with this cold weather
ANSWER : Hi there. Given the description of not being able to start your vehicle, when it is cold and jump starting the vehicle without any problem. This leads me to believe the battery does not have enough cold cranking amp capacity. The engine needs to turn over fast enough to start. This may be nothing more than a weak battery. I recommend having this confirmed by a certified technician from YourMechanic.

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.

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.
