Hi there. The first thing I would recommend would be to have a professional mechanic complete a digital scan of your ECU to see if there are any stored error codes that might pinpoint the source of your problem. However, one thing you might want to check yourself is the electrical harness connected to the crankshaft position sensor. In most cases, if this is diagnosed a being damaged, it’s actually the harness that is bad and needs to be replaced.

The most common reasons a Mitsubishi Galant won`t start are a dead battery, an alternator problem, or failed starter.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
The crankshaft position sensor is located near the engine`s crankshaft, and relays information about the crankshaft`s position as it rotates.
A bad start capacitor – Check the capacitor or replace with a known good one of the same MFD rating. Look for oil leaks. If it`s in a rapid start-stop application, get a motor or capacitor designed for rapid starts and stops. A bad starting switch – That is, if you spin the shaft, the motor will rotate.
There could be several reasons a Mitsubishi vehicle isn`t starting, including a dead battery, faulty alternator, clogged fuel filter, or a malfunctioning starter. To troubleshoot the issue, it`s important to diagnose the root cause and address it accordingly.
Bad Sensors
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.
Check the battery if there is a slow crank and a clicking sound, and the car engine won`t start. However, if the check engine light illuminates, the issue could be the engine or fuel pump. If your vehicle doesn`t start, call AAA, roadside service, or another towing company to take your car to get it repaired.
All Mitsubishi systems from the Mitsubishi 6000 BTU mini split to the 42,000 BTU mini split have at least one wireless remote control. These remote controls have a reset button at the bottom under the panel. Pressing the reset button ensures the remote is working correctly.
The most common cause of a clicking noise in your car is because of low engine oil. If you check the oil level and it`s good, the problem might be a loss of oil pressure or blockage in the system due to dirty oil.
The most common reasons a Mitsubishi Outlander won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons a Mitsubishi Endeavor won`t start are a dead battery, an alternator problem, or failed starter.

My car will not turnover at all! no spark not even does it try to start up i have replaced the distributer starter spark plugs
ANSWER : If the starter motor is not functioning (that is, if the starter is not engaging the flywheel and turning the engine over), either there is no power to the starter or there is power but the starter itself has failed internally.
A qualified technician, such as one from YourMechanic, would first test for voltage (as well as voltage drop) at the starter when you actuate the starting circuit. If no voltage, that is if the circuit is open, the break in the starting circuit is simply traced.
If there is power to the starter and yet the starter will not function, the starter is condemned and thence replaced. YourMechanic can perform these tests to properly diagnose your starting issue right at your location.
My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.
At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.
I have changed the camshaft position sensor, crankshaft position sensor, spark plugs and plug wires and there still is no fire.
ANSWER : Hi there. If there was a spark around the speed sensor as the engine was starting, then there is a major short in the ignition system. Check all of the wiring grounds and make sure that they all are hooked up and clean. If you are referring that the coils are sparking on the outside, then the coil has a crack on them and they would need replaced. I recommend seeking out a professional, such as one from Your Mechanic, to help you with your ignition system.
Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.
2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.
The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.
My car doesn’t turn on, got new battery, changed oil and spark wires and plugs, but when and if it turns on it goes and stalls out
ANSWER : Hello there, many faults will cause your 2001 Honda Accord to have the P0420 code and not turn on. The P0420 code indicates the vehicle has catalyst system efficacy below threshold. This is indicating the car is detecting the cars catalytic converter is not functioning properly or the engine is thought to be running to rich. Common causes of this are a plugged catalytic converter, failed oxygen sensor, leaking exhaust manifold, leaking exhaust, failing fuel injector, or a misfire condition. A qualified Technician such as one from YourMechanic will be able to diagnose your check engine light and car shutting off when driving issues.
