Experienced mechanics share their insights in answering this question :
Hi there. In many cases, the hard cold starting issues you’re experiencing are caused by fuel delivery issues or ignition timing problems. This could be caused by a dirty or faulty air fuel mixture sensor, dirty or clogged fuel injectors, the throttle body or a growing problem with a crankshaft position sensor.
In order to determine exactly what’s damaged, I recommend having a certified mechanic, such as one from YourMechanic, come to your location to complete an inspection to determine why the car is hard to start.

If this only happens first thing in the morning, a weak battery or a drain in the electrical system are likely causes. (You could look for a stuck trunk or glove-box light, but other causes are less visible.) If the slow cranking occurs after driving (engine hot), it`s likely a faulty starter or poor charging.
The problem could be a weak fuel pump, leaking fuel injectors, worn starter, weak battery, or faulty temperature sensor. Good technicians will be able to test and determine the issue more accurately if they can experience the issue themselves.
Bad Battery Symptoms
If the cranking of the engine is sluggish, like your vehicle is harder to start on cold mornings, it starts inconsistently, or there`s no sound and interior lights when you try to start, suspect a failing battery, a loose or corroded connection or electrical draw.
When an engine cranks for a long time before it starts, either spark or fuel is missing or weak and each has its own reasons. Most of the time, the air / fuel mixture has been disturbed and there is too much air or not enough fuel.
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.
Your battery is dead
Below freezing temperatures can cause a chemical reaction in your vehicle`s battery which will lead to produce less electrical current. Cold batteries simply don`t produce the same amount of power as warm batteries, and this is one of the most common reasons why your car won`t start.
A difficult start could be due to a number of things, from a dying battery to a faulty starter. But if your vehicle has a hard time starting after sitting for just a few hours, it can cause an extra layer of confusion. When this happens, one of the most common causes is low fuel pressure.
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.
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.
There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (IAC) valve, vacuum and EGR leaks, inadequate fuel delivery or pressure (clogged fuel filter, injectors), and contaminated or old gasoline.
It`s a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery.
The electrical contacts that power the starter motor can wear out over time due to the high current flowing through them and the spinning motion of the starter motor. As these contacts wear down, they will transfer less and less power to your starter motor causing it to spin slower, making your vehicle harder to start.
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.

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.
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.
Charging warning light comes on when i turn the key and try to start the car and the car want start but when someone tried to give
ANSWER : Hi there:
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.
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.
My car won’t start. It tries to turn over but won’t.
ANSWER : Hi, thanks for writing in. Your battery may need to be replaced. If you don’t have the right about of Cold Cranking Amps your vehicle will fail to start. There is no way to check this though. Also, your alternator could be going bad. Generally alternators fine, but once in a while you will hear about ones that are going bad. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
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.
My car twice out of 4 times today would not start on the first time. Second time started fine. At 2 read lights it was sort of je
ANSWER : Hello, thank you for writing in. Your symptoms point towards an issue with fuel or spark. If you just had work done on the fuel system, you may wan to have your fuel pressure tested at the engine. This will let you know that the lines, filter, and pump are all working correctly. You should also have the ignition system tested. This would mean inspecting the spark plugs to make sure they are in good condition, and making sure the plugs are receiving spark. Testing for spark is best done with a simple spark tester that is inserted into the plug’s wire. If having trouble starting, turn the key to the "On" position before starting, and let it sit. This give the fuel pump a moment to prime. If you do not hear the faint buzzing of the fuel pump priming (you may have to listen closer to the fuel tank), then you may be having issues with the pump. Only further testing will tell. For more help with testing and repairs, contact our service department to schedule an appointment.
