Experienced mechanics share their insights in answering this question :
Hello – lets check basics first. Do you have spark at the plug now? If not, there is still a fault with the ignition. Get the problem codes whether Check Engine is still on or not. If you have spark, but no engine start, spritz a bit of starter fluid into the air cleaner and attempt a re-start. If the engine fires, but doesn’t run, then you have a fuel supply issue. Listen for a running fuel pump when the ignition is turned to the "Run" position. If no fuel pump, check fuses. I would recommend having a car is not starting inspection completed 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.
How to Identify and Fix Common car Problems ?

If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
What the P0336 code means. When the P0336 diagnostic trouble code has been stored in the Engine Control Module (ECM), it is an indication that the “A” circuit of the crankshaft position sensor has a range/performance error.
What Does Code P0336 Mean? P0336 definition: The engine control module, ECM, has detected an improper/irregular voltage coming from the crankshaft position sensor. Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine damage.
There`s a chance the new sensor is a dud or was installed incorrectly. This would cause your car not to start. Or, while installing the crankshaft position sensor, a new problem with your engine occurred. Engines are finicky, and a single misplaced component can cause your engine to not turn on at all.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car. Engine Misfires: A failing camshaft position sensor can cause your engine to misfire.
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.
The P0366 code is defined as an incorrect voltage reading from the camshaft position sensor circuit, specifically for the engine bank 1 camshaft sensor B.
INSTALLATION FAULTS AND WEAR ARE THE MOST COMMON CAUSES OF DAMAGE TO THE CRANKSHAFT AND CRANKSHAFT BEARINGS.
Crankshaft failures may be resulted from by several causes which are oil absence, defective lubrication on journals, high operating oil temperature, misalignments, improper journal bearings or improper clearance between journals and bearings, vibration, high stress concentrations, improper grinding, high surface …
If your crankshaft sensor is bad, your car usually won`t start. This is because your engine doesn`t get any information from the ECU or PCM regarding your crankshaft, so the vehicle will think there`s a transmission or fuel injection problem.
Lack of Spark
Contaminated or fouled spark plugs are unable to ignite the fuel, which could be causing your no-start condition. Like the spark plugs, the ignition wires also need to be periodically replaced.
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.
Battery Current Sensor Problems
Dirt and Debris: Dirt, debris, or corrosion on car batteries can penetrate into the sensor causing malfunctioning. This failure can lead to a number of electrical problems including no-start.
Connect your meter leads to the sensor pins. Make sure to keep your meter lead wires away from engine moving parts during this test. Have an assistant crank the engine for a few seconds while you watch the meter`s readout. The sensor should produce a voltage pulsing signal.
There are a few things that can cause the crankshaft position sensor to fail, including damage, debris and faulty circuitry. Even for modern electronics, the engine is a violent and destructive environment. Though built for this, most sensors eventually succumb to the ever-present heat and vibrations of the engine.
The P0315 code indicates that the crankshaft position sensor (CKP sensor) has gathered certain information about your crankshaft position that wasn`t actually stored in the memory of the powertrain control module (PCM).
СКР sensor sends signal for the speed and the position of the crankshaft to the onboard controller. This signal is a series of repetitive electrical voltage impulses, generated by the sensor when the crankshaft is rotating.
Before connecting, clean the sensor with a cleaning solution and let it dry. Connect the sensor`s three wires to their original place. Reconnect the battery and restart the system. You have thoroughly disinfected the camshaft position sensor.
A faulty crankshaft sensor will cause your engine to misfire as incorrect fuel injection readings weigh in. When this problem becomes especially apparent, the engine may stall and have difficulty restarting.
Spun rod bearings are the most common failure. A spun rod bearing will tear up the big end bore in the rod, ruin the rod journal on the crankshaft, and sometimes break the connecting rod. That`s really bad news because a broken rod flailing around inside an engine can obviously do a lot of damage!
If the timing belt or chain has broke then you may have bent the valves and the chain or belt will jam up the crankshaft from turning. The pistons will contact the calves and engine will not turn.
The crankshaft position sensor is the most important of all engine management sensors, and the engine will absolutely not run without it.
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.

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.
When my car gets warm and I stop at a light or stop sign it shuts off only after car get warmed up I’ve changed a few things but
ANSWER : Hi There,
It sounds like you may have a failing ignition coil. The 15-20 minute gap in between when you are able to start your car sounds like something called heat cycling. This happens when ignition coils begin to fail due to excessive heat and shorting out. Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeatedly The insulation develops small fractures that open when heated and close when cooled. When open, they allow shorting of coil windings and decrease or eliminate the coil’s ability to function. This type of temperature cycling happens because every time you shut the engine off, the fan stops running, the coolant stops flowing and the temperature under the hood rises. Every time you start the engine again the coolant flows, the fans turn on, and the temperature drops. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to properly diagnose your ignition system.

I had a p0405 get code replaced egr valve, map sensor,mad sensor, and PCv valve just to be safe but still getting the code why?
ANSWER : The code P0405 and a rough idle is most likely due to carbon getting into the EGR pintle. This will hold the EGR open. When you are getting the rough idle you should shut off engine and remove EGR valve. Check to see if carbon is holding the pintle open. If it is then you will have to remove the carbon from the pintle. Then try and clean out the EGR passages by scrapping them using a round wire brush. Afterwards, start the engine for a few seconds with valve removed to blow out loose carbon. You should then spray a small amount of carbon cleaner into the passages to dissolve the carbon. Lastly, reinstall the EGR and reset the light and codes.

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.
I filled my car up with gas, drove about a block to get a newspaper, put it in park and it died before i ever got out of the car .
ANSWER : With a car that cranks but won’t start, there are a few things that need to be checked. But before I explain them, there is a common thing that happens with Nissan’s. Every once in awhile they will flood the cylinders with fuel and wash the oil film off the cylinder walls and rings. This will reduce compression enough that the car will not start. Fortunately, there is an easy fix for this problem. It is what is known as clear flooding.
Hold the gas pedal all the way to the floor while cranking the motor. It won’t start immediately and when it does it will not run very well at first. Feather the throttle to keep it running until the motor clears out the excess fuel and the motor begins to run smoothly. If after cranking the motor with the gas pedal held to the floor for at least
Changed camshaft sensor but car still won’t start, could it be the crankshaft sensor?
ANSWER : Hello, thanks for writing in. Most of the time, this code comes up when there is a difference between the crank and cam sensors. The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression. If there is then the timing belt is the problem.

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.
