How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most common reasons a Jeep Cherokee won`t start is because of a bad battery, corroded battery terminals, or a bad starter. Other common reasons a Jeep Cherokee won`t start are a bad alternator and a broken or failing fuel pump.
A lack of gas is one of the most obvious reasons why your Jeep Cherokee may not be starting. If the vehicle is out of gas, it won`t start. So, be sure to check the fuel level before starting the Jeep. It`s also a good idea to keep a full tank of gas in the Jeep to avoid running into this problem.
The most common causes for a Jeep failing to start despite its radio and lights working are issues relating to its battery or other cranking/start-up components, such as the ignition switch, starter, or spark plug. These pieces might be damaged, dirty, or corroded.
Bad or Dirty Spark Plugs: Spark plugs are responsible for igniting the fuel in the combustion chamber. If they are not working correctly or are dirty they don`t ignite the fuel cleanly and the car can misfire or sputter. The plugs will need to be replaced or cleaned.
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.
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.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
A sputtering engine may just mean you need to have your fuel filter replaced. All vehicles have a series of vacuum hoses that create the fuel pressure. If one of them leaks or is damaged in any way, you will lose significant fuel pressure. The vehicle`s exhaust system can greatly impact the engine`s performance.
The most common cause of a sputtering engine is an issue with the fuel delivery system; these include; the pump, filter, and injectors. These components work together to ensure fuel flows smoothly from the tank to the injectors, pumping into the engine evenly.
The clicking noise you hear may be related to a weak battery that is simply too weak to turn the engine over. when this happens, the battery will direct the power it does have to the starter which engages the flywheel when you turn the key trying to turn the motor over.

I put in a new starter and battery and my Jeep will not start. Please help me get my Jeep to start.
ANSWER : Hi there. Check to see if the wiring to the battery and the starter are tight and clean. A bad connection will cause a no start situation. If the battery cables and wires are all tight and clean, then go in the cab and turn on the ignition switch and see if any thing in the cab works.
If nothing comes on, then check the fuse box for any blown fuses. If all the fuse are good in the cab and under the hood, then the ignition switch needs replaced. If the ignition switch is good and the accessories come on, then either the starter relay in the fuse box has failed or the wires from the starter relay to the ignition switch has become burned or loose. Check the wires from the starter relay on the starter to the ignition switch. If everything checks out to be good, then the ignition switch needs replaced.

Sometimes the truck will start and run just fine, and other times it will barely want to start and I need to press the gas pedal
ANSWER : Hello. This can be caused by a few different things. If the vehicle will run by pressing lightly on the gas pedal then it may be a bad idle control valve. If it sticks, it will allow too much air into the engine and cause it to run like this.
It can also be a weak fuel pump or an air flow meter issue. If the engine runs fine once it is started, then I would check the computer for codes first. If none are present, then I would run the engine and see what the sensor readings are to see if anything comes up faulty.
If those are also fine, then I check the fuel pressure to see if the pump is getting weak or to see if the pressure bleeds off while the vehicle sits. If you are thinking of having this starting issue inspected, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this problem.
Why does my car struggle to start every 4th to 5th time?
ANSWER : It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.
Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.
Warm engine, long starting and feels like it isn’t getting gas, 10 sec, then takes off like nothing wrong. Doesn’t happen all time
ANSWER : The biggest challenge with your symptoms is they are intermittent. Intermittent symptoms are often difficult to duplicate and we can’t diagnose something that is working. The biggest challenge here is recreating the symptoms. While attempting to recreate the symptoms, I would have a scanner connected and recording all the data. If the problem arises, it will be recorded and I would most likely be able to see what happened in the scan data.
It is good you are taking notice of the conditions that the symptoms cause. This information will be valuable for a technician to pinpoint the problem. As for what the problem could be, it could be many things. The fuel pump could be binding and not delivering enough fuel, the TPS (throttle position sensor) may be glitching or a crank or camshaft sensor maybe sending false information. Camshaft and crankshaft sensors are common failures on Civics. So these two sensors would be suspect, as well as the wiring harnesses that feed them. Poor electrical connections are notorious for symptoms such as these.
The long story short is someone will need to catch the culprit sensor in action, which is the biggest challenge with intermittent problems. With my own vehicles, I often wait until the failure becomes more regular to diagnose them. It saves a lot of time.
I recommend the loss of power inspection to help you figure this out.
Good luck!
Ok car starts and runs fine normal idle but once it gets up to warming temp it’s like it starts to bog and dies.
ANSWER : With the randomness of the codes you are pulling, it is hard to determine what they have in common. When diagnosing mechanical errors like this, keep it simple. Due to the loss of power and stalling issue, I would like you to look at the one component that may have a huge effect over all of theses parts.
The ELD is a unit which measures the amount of power coming from the battery. It allows the alternator to adjust the field, and the amount of power generated by it. If you are experiencing issues with the ELD, which allows the battery and alternator to behave incorrectly, the other electrical components in the vehicle will not work. You may have more than one issue that is all coming to a head at once.
You can test the ELD with a multimeter, but any electrical testing can be dangerous, and we recommend you proceed with caution. If you’re not comfortable with this repair, consider YourMechanic, as one of our mobile technicians can come to your home to diagnose the stalling issue firsthand and help you make the necessary repairs.
My Jeep started fine. I adjusted the tilt steering. The airbag light came on but it continued to run fine. Shut Jeep off and would not start again
ANSWER : The air bag light comes on when the computer detects an issue with the vehicle’s air bag safety system. This can have many potential causes, including a faulty sensor, wiring, air bag unit, computer, among other things. If you were having issues with the steering column, it may be possible that one of the airbag system components located in the steering column, such as an airbag module or sensor, has had an issue. If these components are linked to the starting system then this may be part of the reason why the vehicle is not starting. If the engine is cranking when you turn the key, then that is a good sign that the starter is getting power, so that rules out most of the no start issues related to the starting and electrical systems.
It may also be possible that the no start condition is a completely separate issue from the airbag light, as there are many things, not related to the airbag system, that can cause a no start condition. A few common non air bag related causes are issues with the fuel, ignition, or engine management systems. If any of the components to these systems, such as the fuel pump, ignition coils, or an engine management sensor, fail or have an issue, they may cause the vehicle to Retrieving the trouble codes using a scan tool capable of reading airbag system codes as they will likely shed some light on what the cause of the issue may be, or if the two are related. If you are unsure, I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose and repair the cause of the no start condition.
