Car won’t turn over
Car has a new starter, but will not turn over. The battery also is good.
Experienced mechanics share their insights in answering this question :
Hello, when a vehicle doesn’t start,there are two things to check, the base engine and the electrical circuits to the starter motor. The base engine is easy to check, by seeing if the crank rotates with a ratchet and socket on the damper bolt. If the crank fails to turn, a base engine problem needs to be looked at. For the starter there are two wires at the starter, a big red wire that usually comes from the battery and a smaller wire that is connected to the solenoid. The larger wire should have 12v at all times and the smaller wire should have 12v with the key in the start position. If there is no power present at the starter at either wire then some electrical testing will need to be performed. With no power present and the smaller wire the circuit will have to be traced back to a relay and the relay traced back to the ignition switch. You may need the aid of a mechanic to check the motor and the electrical system of the starter.

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.
Why your car struggles to start but runs fine. There are a number of reasons why your car might be slow to start but runs as-normal once it gets going. Causes can vary from weather conditions to battery health, wiring issues, starter motor concerns and fuel-pump health.
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.
If you continue having difficulties starting your car in the morning, you may have a drain on your battery somewhere, or you may need a new alternator.
The three main reasons why an ignition key will not turn include: problems with related components, issues with the key itself, and ignition lock cylinder problems. Tip: Always make sure your parking brake is on to keep the vehicle secure when following these steps.
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.
Flat or faulty car battery
A flat battery is the most common reason your car won`t start and can be caused by a number of things, such as lights being left on, something in the electrical system causing a battery drain, or even a faulty battery that won`t hold its charge.
Starter motors should make noise when you turn your ignition key fully to activate your car. If you turn the key and do not hear anything, there`s a chance that there`s something wrong with the vehicle`s ignition switch.
The primary culprits here are fouled spark plugs. Spark plug electrodes wear down over time, increasing the voltage needed to jump the gap in the plug and ignite the fuel and air mixture in the cylinder. That leads to longer cranking times before an engine fires up.
A: Possible causes: a marginal battery, a poor connection in the starting circuit or starter, a charging-system problem, or the battery is being drained while the car`s parked. If this only happens first thing in the morning, a weak battery or a drain in the electrical system are likely causes.
Having all the lights go out completely when you crank is typical of loose terminals, loose ground, dead cell in battery, a really discharged battery, or a dead short somewhere. The volt meter will tell you alot.
Usually a rapid clicking noise is a good indication that your starter motor isn`t getting enough electrical current to engage – basically your solenoid is trying to engage but can`t make the connection.

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
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.
Engine turned off but inside of car still on, now engine won’t turn back on.
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.
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.
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.
My car shuts off when I turn on the light or even the turn signals please help need this car to get to work
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.

Hi there. It is quite possible that the starting issue you’re currently having with your Ford Focus is not related to the starter replacement. However, it could be due to might be due to your battery problem. When your battery does not have enough power to engage the starter, it also impacts other important systems critical to maintaining ignition, ranging from the ignition coils to fuel system components. It might be a good idea to have a professional mobile mechanic from our team come to your location to compete a car starts then dies inspection, so they can correctly diagnose this issue and ensure the right repairs are made.
car won’t start.
A possibility is a faulty ignition switch. If the switch opens after the car starts, the engine will shut off. But, that is just a possibility and a diagnostic would have to be performed to rule that in or out. Be sure you have a fully charged battery that passes a load test. Starters motors can display intermittent operation if they are faulty. With a fully charged battery, if the starter motor does not run that signifies an electrical problem in the starter circuit (includes the ignition switch) or a problem with the starter motor itself. If there is power to the starter motor and yet it doesn’t run, the starter is condemned and replaced. Alternatively, if there is no power to the starter, or there is a big voltage drop anywhere on the circuit to the starter, then the circuit has to be traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. Regardless of what the underlying cause of the no start condition is, if you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you.

The steering lock may not be unlocking either due to a faulty ignition lock housing or more commonly as the cars age a faulty spring at the steering wheel on the under side of the column. If the ignition lock housing is the issue the housing can be replaced. It s a bit tricky as the mounting bolt has break off heads and generally need to be driven out with a punch. If the lock is not disengaging because of a faulty spring on the ignition lock many owners have had the spring removed by having it drilled out of the housing. However, removing the spring may permanently disable the steering lock. The last option would be to replace the steering column. You may want to enlist the help of a mechanic who can recommend the proper repair for your situation.

If your vehicle was not starting but was turning over, I would have advised against the starter replacement. If the engine will turn over, the starter is doing its job. If you have an aftermarket security system on your vehicle, are unable to start your car, and are unable to lock and unlock the doors, I would recommend having the aftermarket security system inspected. The best place to have this done would be the place that it was originally installed as they would have the best knowledge of the system. This could be related to wiring, control modules, or other related components. Once the security system has been inspected, the repair procedure will be more clear.
