Car doesn’t turn over right away sometimes

When I go to start my car sometimes the Engine doesnt turn Over for approximately 4-5 seconds. I was wanting to know if I could get a hypothesis on what could be wrong.

My car has 104462 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
A slight delay by the starter like this is often a bad high current connection somewhere along the power path from the battery to the starter. It literally can take a second or three for battery power to overcome corrosion, or a poor physical connection. A confirmation of this diagnosis would be – when the starter does kick off, does it sound like it’s turning the engine over slower than it should be? If so, this confirms the problem. A bad high current connection can be where the battery connects to the cables, the battery cable connections to both the engine ground and the starter respectively, poor ground connectivity between the engine and the chassis, burned contacts in the starter solenoid, and worn brushes in the starter motor itself. It is possible also that the ignition "start" trigger path, which runs through the ignition switch (possible burned contacts), and triggers the starter solenoid, may also have poor connectivity along the way. I would recommend having an Car Will Not Start Inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs.

If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.
When it comes to the vehicle not starting, and not having electrical power, always start by checking the battery. In your situation you can go remove the battery from the vehicle, and take it to have it tested. If it is bad, simply replace it and drive the care home.
Bad Spark Plug Or Broken Distributor Cap/Rotor

If you have a good battery and enough fuel in the gas tank and your car still won`t start, chances are you have a bad spark plug. Why? A bad spark plug will prevent fuel ignition, and the vehicle won`t move.

The cause of this problem is usually one of 3 things – a failed starter motor, a bad connection between the battery and starter motor, or a blown fuse (if present) in line between the starter and the battery.
The slow cranking can be due to a defective starter, bad cables or connections to the battery, or a bad battery. If the engine is turning too slow it can cause low voltage to the fuel injection and fuel pump causing the no starts.
The starter is part of your car`s electrical system and subject to blown fuses and short circuits. When you`ve been desperately attempting to start your car, the starter can overheat making electrical issues—and the accompanying smoke—more likely.
Put simply, your alternator keeps your car battery charged, allowing you to turn on your car and use electronic accessories such as your headlights and radio. If you`re experiencing car alternator problems, you may find that your car won`t start or stay on for more than a few minutes.
Check the battery if there is a slow crank and a clicking sound, and the car engine won`t start. However, if the check engine light illuminates, the issue could be the engine or fuel pump. If your vehicle doesn`t start, call AAA, roadside service, or another towing company to take your car to get it repaired.
Problem Description

If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the “OK to start” signal.

The starter relay is one of the most critical and often overlooked components in any vehicle ignition system. The starting relay is a small electrical device located in the starting circuit of a large current motor. The relay is just a remote control switch that regulates the current in a high-current circuit.
One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn`t, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Battery Current Sensor Problems

Dirt and Debris: Dirt, debris, or corrosion on car batteries can penetrate into the sensor causing malfunctioning. This failure can lead to a number of electrical problems including no-start.

If the ignition switch fails while the engine is still on, it may cut off power to the ignition and fuel systems, which will cause the engine to stall. Depending on the exact issue, the vehicle may or may not be able to be restarted a short while later.
If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.
When you have a bad starter solenoid, the starter motor won`t work. This means the engine won`t start when you turn on the starter switch or press the start button. However, if your vehicle has an automatic transmission, the engine could sometimes not crank because of the neutral safety switch.
Symptoms of a burnt out diode:

The engine will begin to run rough, lack power and eventually stall and not start again. The battery warning light will turn on, warning you that there is a problem with your alternator charging system. The headlights will become dim due to reduced battery voltage.

Several things can cause a starter relay to fail, including corroded contacts, a faulty circuit, contacts that weld together, or just a relay that`s too old.
The battery can be fully charged but still not be able to start the vehicle if it is failing or has a dead cell. Other likely issues are the fuel pump, ignition switch, battery cables, starter, or a clogged fuel filter.

The starter is what turns your engine over, and it draws a lot of power from the battery to do that. Therefore, when you have a bad car battery, the starter doesn`t have enough ability to turn the engine over.

the most relevant questions and answers related to your specific issue

As I’m driving, all my lights inside/out of the car turn off and the car still stays on. But when I turn the car off it won’t turn over
ANSWER : Hello there. The charging system on the car may not be charging the battery as you drive and the systems that keep the engine running are priority so the engine will stay running until the voltage drops below about 9 volts but the lighting and some other accessories may cut off above this voltage first. You should have the charging system tested to see if the alternator needs to be replaced.

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.

Engine turned off but inside of car still on, now engine won’t turn back on.
ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.

My car shuts off when I turn on the light or even the turn signals please help need this car to get to work
ANSWER : Hi there. This type of electrical glitch can be very difficult to pinpoint or diagnose without a physical inspection. However, in general, the most common causes of this issue is an exposed electrical wire within the ignition system. It is best to have a professional mechanic complete an electrical problems inspection first in order to correctly diagnose and resolve this issue.

steering wheel turned to the far right and locked in place while the wheel are straight. and I can’t turn the key.
ANSWER : Hi there. From the description you have provided, concerning your vehicle’s steering wheel is locked far right and key won’t turn with the front wheels in a forward default position, is somewhat confusing to me. It could be, undo pressure is being applied to the steering wheel lock. You could try, physically moving the left front tire side to side in either direction, to relieve the pressure on the steering wheel lock. It could be, the key you are using has a problem, try another key if available. It could be, the ignition lock cylinder is at fault. I recommend having your vehicle’s can’t turn the key be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Car stalls when idling
ANSWER : Your problem may or may not be associated with the engine cleaning. But for a moment, let’s assume that it is. You hit the right spot when you changed the distributor cap, but if there are any covers or tubes that the wires go through that could hold moisture, they will need to be uncovered and dried out. There could also be moisture accumulation in the boots where the spark plugs connect. So take them off and make sure that they are dry.
Other reasons for a car to shut off while it is idling are air leaks or problems in the idle air control valve. Air leaks could have been caused by the cleaning if a high pressure hose was directed onto a vacuum line or a rubber boot and pushed it off slightly. So check the vacuum lines and rubber parts under the hood for proper fit. If there is a problem in the idle air valve, that is probably not related to your washing and will need a proper diagnosis. If you contact Your Mechanic you can have a technician come to your home or office to diagnose your problem and tell you what needs to be done.

When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
