Hi there. After looking at your list, I’m curious if you’ve replaced the fuel filter or cleaned the throttle body and fuel injectors? In many cases, these components are the source of hard to start problems; if you’re not getting fuel to the throttle body. It’s also possible that the fuel pump is either not properly installed, or an obstruction exists in the fuel line. You might want to have a professional mobile mechanic come to your location and complete a car is hard to start inspection; so they can help you pinpoint the source of this problem.

The most common reasons a Jeep Cherokee won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
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.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Failing Battery or Starter Motor
If a battery is low on energy, or if the connections are loose, your engine may be able to crank, but it may not start–or it may take several tries. Similarly, a starter motor that`s beginning to fail may still crank the engine, but won`t be powerful enough for it to start.
Most of the time, NO, you can`t jumpstart a car with a bad starter unless you repair it. When the battery is dead, jumper wires or boosters are employed. You use a second battery to provide the necessary electricity to start the car.
Common signs of a faulty neutral safety switch include the engine not cranking in park or neutral, not cranking at all, or cranking in any gear.
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.
It might be a battery or alternator problem
If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!
With a cranking system, symptoms are divided into one of three possible troubleshooting categories: Click — No-Crank (solenoid clicks but starter doesn`t crank) No-Click — No-Crank (solenoid doesn`t click/starter doesn`t crank) Slow Crank (starter cranks, but engine RPM slow to start vehicle)
It could be a bad battery, failing starter, or some other component in the electrical chain that comprises the starting system. The starter typically consists of two main components: the motor itself and a solenoid used to switch positive battery voltage to a motor terminal.
Starters Can Fail Due To Low Battery voltage
Typically what happens is the excess current created as a result of the low voltage causes the contact within the solenoid to weld together or even burn through.
Repeated attempts to start a vehicle using batteries with a low state-of-charge can damage a starter motor. Insufficient voltage and current at the solenoid terminals [switch (50) or S-terminal and the switch (30) or battery post] also can cause starter damage or failure.
When you attempt to start the vehicle, is there a clicking sound, but it won`t turn over? That may be a good sign. If a jump gets the car running, but won`t turn over again once it`s shut off, a dead battery is likely the cause.
To test a bad neutral simply test the known hot to a good ground. Hot to ground should return nominal voltage ~ 110 – 125 Volts and hot to neutral would read something irregular. In the case the ground is either bad or missing simply run a drop cord from a working properly grounded outlet and test hot to ground.
The neutral safety switch will not allow the car to start unless the car is in park or neutral. This switch is located on top of the transmission.
Potential Vehicle Damage
You will wear out your brakes much quicker When driving in neutral, drivers become reliant on the mechanical brakes due to the engine brakes disengaging. This can wear out the mechanical brakes much quicker.
The switch is basically a relay — it receives a constant power source when the key is in the on position.

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
If rusting is the issue, you can bypass the bad starter solenoid wire. To do so, use a 12V wire to directly provide current from the car`s battery to the point where the starter and solenoid connect. You`ll hear a click sound indicating that the connection is made. Now turn on your ignition system.
Why won`t my car start but the battery is good? 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.
A manifold vacuum and/or barometric pressure, throttle position, engine RPM, coolant temperature, and vehicle speed sensor all modify the timing program.
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.
It requires a good deal of energy to crank the car`s motor, and if a battery is not replenishing its power properly due to a faulty alternator, it will become drained and ineffective. You will hear a clicking noise while attempting to start the car, and the engine will have difficulty turning over.
