hello, I am trying to have a mechanic diagnose my dodge charger no crank problem.

the car does not crank at all its not battery related. I suspect neutral/park safety switch or computer but would like to verify prior to taking it to the dealer to reprogram

My car has 82000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. Check the neutral safety switch to see if there is any loose wiring or moisture on the harness. Check to see if the transmission position is in park or neutral when trying to start the engine. If the switch seems good, then there could be an issue with the ignition switch. Try checking to see if there is power to the accessories in the vehicle. If the radio, lights, and window motors will not work, then it would be with the ignition switch. But if the accessories work, then the neutral safety switch could be damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over. Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright.
A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box. This box is usually installed on the driver`s side of the vehicle.
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.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down.
Some vehicles may exhibit a powertrain control module (PCM) concern that results in no crank, no start or malfunction indicator lamp (MIL) with one or more diagnostic trouble codes (DTCs) present.
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.
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 relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition. You may find that turning the key may power on the accessories, and may even crank the engine.
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.
These two types of sensor help the electrical control unit (ECU) calculate the position of two key parts of the engine: the camshaft and the crankshaft. The crankshaft position sensor is attached to the engine block facing the timing rotor on the crankshaft.
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.
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.

ANSWER : Hi there. Check the neutral safety switch to see if there is any loose wiring or moisture on the harness. Check to see if the transmission position is in park or neutral when trying to start the engine. If the switch seems good, then there could be an issue with the ignition switch. Try checking to see if there is power to the accessories in the vehicle. If the radio, lights, and window motors will not work, then it would be with the ignition switch.

When I go to crank my car the key stays in the start position and the car is constantly trying to crank itself.
ANSWER : First, let’s make sure about some terminology before I proceed. I will assume the motor is actually turning over. If the car is trying to start, the motor has to be turning over or it is not trying to start. This is an important distinction when diagnosing the starting system. As a technician, I go to different parts of the system based on this description.

If the key is stuck in the start position, this is a ignition lock cylinder issue and the reason the starter continues to turn the motor over. If the starter is turning but the motor is not, then the starter is likely the problem. Either that or the teeth on the flex plate are all gone. This would require removing the transmission to repair.

If the car runs intermittently, this can be a big challenge. And it also means the starting system is working. It will need to be diagnosed when it is failing. A working car cannot be diagnosed because there is nothing wrong. Where you park your car should not have any affect. It certainly could be a wiring problem. Wiring problems hide really well and can happen anywhere in the miles of wires that are in your car. Isolating the system that is failing is really important here. At the moment I am unsure which system is failing. Starter system, ignition lock cylinder and or ignition switch electrical or something with the engine control system.

When the car is failing, you need to check for spark and fuel pressure. If neither is present, this is a clue. Usually the crank sensor will do this. Does your car have a tachometer? If so, does it move at all when cranking. This is a clue whether or not the cam and or crank sensor is working. Is there a Check Engine Light on with the key on? If there is a Check Engine Light, the code or codes can be used for specific diagnosis.

All of these concerns will send you down a diagnostic path. Be sure not to confuse yourself by misinterpreting multiple system failures. If the key does stick in the start position, this would be the first problem to solve. After that, does the motor actually turn when the starter turns? After that, the question of "Why won’t it start?" is first answered by finding what the motor is lacking. Fuel, spark etc… Good luck.

If you need assistance with these checks, contact a certified mechanic who has the tools and experience needed to properly diagnose this starting issue with your car.

Caliber turns over but won’t start?
ANSWER : Hi there. Assuming, you have reinstalled the original PCM (powertrain control module) and still won’t start, circuit tests for the crankshaft position sensor need to be performed. A poor connection or broken wire could be the cause for the no start condition. It could also be the PCM is at fault and the replacement does require programming. There are other possibilities for a no start condition, a faulty PCM relay, a faulty ASD (automatic shutdown) relay, fuel related issues and ignition system issues. I recommend having your vehicle’s no start be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Connect battery up to car, car then tries to start by its self without key in ignition. What can be problem
ANSWER : Hello, thanks for writing in about your Oldsmobile Aurora. A bad starter solenoid could make the starter run, but would not activate the ignition switch, so the engine could crank but not run on its own. I would recommend testing and/or replacing the starter solenoid. If you need assistance with fixing this issue, contact a certified technician, like one from YourMechanic, to diagnose the starting issue firsthand and help you make the necessary repairs.

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.

I tried to crank it but it wont start and the lights dim when trying to crank it
ANSWER : Starting systems are typically very simple. For the most part, you will be concerned with the battery and the starter. It sounds like your battery is dead. I would first attempt to jump start it.

If using another car to jump start your vehicle: attach the red (positive) terminal of the vehicle that is running to the jumper cable. Then hook the black (negative) terminal to the jumper cable. Connect the other end of the cables to the red (positive) and then black (negative) terminals on the dead vehicle and then attempt to start your vehicle.

If this doesn’t work, you will want to turn your attention to the starter. The starter can be bench tested, but these tests can give you false positives. If the issues is not related to the battery or the starter, you will want to look into the ignition. The neutral safety switch can cause starting issues as well. But it is highly likely this is a dead battery or a bad starter. If you would like to have this problem taken care of for you, a qualified professional from YourMechanic can come to your car’s location to diagnose the starting problem and guide your through repairs.

My car won’t start 2001 Dodge Stratus
ANSWER : Hi there – your problem may be a weak fuel pump, and a bad starter solenoid (relay). The whine you now hear while the key is turned on is probably the fuel pump – a good sign. The fact that you now don’t seem to be getting starter engagement may indicate that the starter solenoid is not sending current to the starter motor, despite having a good battery. I would recommend a starter system inspection](https://www.yourmechanic.com/services/car-is-not-starting-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

its cranks slow, sometimes it cranks fine and other times i have to crank it twice, it happens randomly
ANSWER : A slow cranking condition is caused by not getting enough power to the starter. Since you replaced the starter then you may have a weak or borderline bad battery. One of your cables may be bad causing the slow crank condition.

If the battery is weak then you may get the problem one time and a sudden burst the next. If you battery is more than a couple years old I’d suggest having it load tested to see if it is bad or if is a cable problem.

Do not rule out the starter even if the problem was fixed for a while after the starter was replaced. I’d suggest getting your vehicle inspected by a qualified professional, such as one from YourMechanic, to diagnose your starting issue and repair it as necessary. Good luck.
