All of a sudden my car won't start. It had been running fine before that. It is so strange. The radio and lights work, but it won't start. Sometimes you have to shake the battery cables and other times you need to put it in neutral and it will start. I have taken my car into the shop many times, but they can't find out what is wrong. Do you have any ideas?
For the vehicle to start, many different systems must work. The most common causes of no-start conditions are the battery, starter, battery cable, ignition switch, or the fuel pump. Any of these can be intermittent issues, which will not always act up. Given that you have had success with shaking the battery cables, this may indicate that one of the cables is failing. A qualified technician, such as one from YourMechanic, will be able to diagnose your starting issue and perform any repairs required.

If your car won`t start, the likely culprit is your electrical system—namely, the battery, alternator or starter. Your car battery provides your vehicle with the power it needs to start.
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 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.
This same battery is used to power absolutely everything in your car. In fact, it`s even crucial in starting the engine and getting the car going at all. As the radio plays, it draws power from the battery, meaning that it`s possible for your car battery to die while listening to the radio.
The most common car electrical system problems are problems with your car battery, an alternator that isn`t working properly, loose or failed spark plugs, a fatigued solenoid or starter, bad battery cables, electrical fuses that are blown, loose wires, or problems with your ignition switch.
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.
The most common reasons a Jeep had no power relate to the fuel system or the Jeep battery. Other common reasons include wiring issues, a bad alternator, or exhaust issues. Start with checking the battery and that the engine is getting fuel.
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.
Excessive charges coming from alternator and car battery can entirely damage the starter systems of the car.
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.
Slow or Malfunctioning Accessories
That way, if you`re driving with a failing alternator, you`ll lose power to your radio (or other nonessential accessories) before losing power to your headlights.
If the car won`t start at all and the dashboard lights are flickering, it`s likely that the battery does not have enough charge to crank over the vehicle. In this scenario, you`ll likely need to replace the failed battery.
There are a total of four possible failures that can take place in an electrical circuit: an open circuit, high resistance, short-to-ground and short-to-power.
There are mainly three types namely line to ground (L-G), line to line (L-L) and double line to ground (LL-G) faults.
It can be occurred due to poor wiring in the house or lightning strikes or faulty appliances or damaged power lines. Surges are common and last for a microsecond but if you experience frequent surges lead to equipment damage that degrade life expectancy particularly.
The most common symptom is dimming or flickering lights. This can happen because the electrical current is being interrupted, which causes the lights to dim or flicker. Another common symptom is a blown fuse. If a fuse blows, it`s an indication that too much current is flowing through it.
Examine the circuit board and search for signs such as crushed components, bulges, damaged wires, cracks, misplaced or extra solder, burn marks and scratches that indicate that the board is either bad or requires replacement and professional assistance.
If there is no sound when you turn the key, but the lights and accessories work, it could be the stater relay or starter solenoid. However if there is no sound at all, not even a click, it`s probably your battery.
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.
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.
Loose wiring, corroded connections, damaged starter components, oil leaks, and a bad relay or fuse are some of the reasons why a starter can fail. As the driver turns on the ignition switch, a current for the starter should flow and get the engine running. If not, the starter might be faulty and require replacement.
Fortunately (spoiler alert) the root cause of a no-crank is almost always simple. Most of the time it`s simply due to a low or dead battery, or voltage drop through a corroded connection. Rule those out before you suspect the starter itself.
A TIPM is an acronym for Totally Integrated Power Module which controls the electrical system in your car. It is a black box made of hard plastic that has power board and fuses inside.
