When cranking the engine, there are a few sparks on the ignition coil and then they cut off
i checked all the fuses engine cranks fine when put ignition coil to ground there are a few sparks engine comes on, then the sparks cut off and engine dies.
i suppose it is the crankshaft or the camshaft sensor inmittent.
injectors pulse , because exhaust smell like raw gasoline.
the green keysymbol on the dashboard is flashing.
can you help me?

The most common reasons an Acura MDX won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons an Acura MDX key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key. Search our network of RepairPal Certified shops near you to speak with a technician about your issue. Oops! We got lost!
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
What Does Code P0301 Mean? P0301 definition: Cylinder 1 misfire detected. Diagnosis: A misfire can be caused by anything from faulty spark plugs to low engine compression.
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.
3 coils is all that is required on these vehicles because of the coil and spark plug wire set-up.
P0306 indicates that cylinder #6 is experiencing misfires.
P0301 is a diagnostic issue code “Cylinder 1 Misfire Detected.” It means that the powertrain control module (PCM) has counted enough misfire events on cylinder 1 to save the misfire code for that cylinder.
Since many different errors share these symptoms, you may wonder, “What does the code P0301 mean?” This error indicates that cylinder #1 isn`t firing properly because there`s not enough fuel in the air/fuel mixture. As a result, the cylinder isn`t moving at the correct rate.
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. It can be hard to determine if you`re dealing with a battery or an alternator problem.
If the car clicks when trying to start, but still won`t start, this can be caused by a weak battery, dirty battery terminals, a worn starter motor or a stuck solenoid. If might just need a jump start, but there are a few tricks to try before breaking out the jumper cables or electric jump starter.

the most relevant questions and answers related to your specific issue
I have no spark, no ignition, no current is going to the ignition coil. Could this be a Auto Shut-Down Relay?
ANSWER : The automatic shutdown (ASD) relay powers the coil and is turned on and off by the engine control module ECM. If you scan the engine and get a code 40, then you may have a bad ASD relay, but there is a pinpoint test to follow in order to reach this diagnosis. I suggest replacing the relay with a known good one to see if it starts and runs. If it still does not start, then there is a long pinpoint test to follow in order to diagnose your car’s trouble starting.
Engine crank, no coil spark, fuel pump does not kick in.
ANSWER : Hi there. There could be multiple issues causing your lack of spark problem, ranging from a minor electrical short in the main relay to an issue with your ECU. In order to know for sure, you should have a professional mobile mechanic complete an electrical problems inspection.
Engine light fault. There was a bad spark plug and a failed ignition coil. Replaced both the coil pack or spark plug.
ANSWER : Hi there. If the light is coming on then shutting off and returning on, then if the issue is for the same coil, there could be an issue with the wiring on the coil plug. Check the wiring on the coil plug and see if the wires are split, broken, or burned. If there is nothing wrong with the plug, then the main engine harness has an issue / short and may need replaced. If you need further assistance with your ignition system, then seek out a professional, such as one from Your Mechanic, to help you.
Changing spark plug or ignition coils
ANSWER : Changing spark plugs at 46000 isn’t necessarily a bad idea, but mostly I say that because it will keep them from seizing to the cylinder head. Most late model cars like yours can run a set of plugs for longer than that. As for the coils, If the car is not misfiring, I don’t see why you would want to change them and neither does the maxcare company. If the car IS misfiring, then the check engine light will come on and it will set misfire codes. So I don’t see why it would be necessary to do it just yet. If you want to get a third opinion on that, you can contact Your Mechanic to have a technician come out to your home or office to check out your BMW and tell you just what it needs.
Engine cuts out/off at idle, and cuts out sometimes at steady state (60-70 mph).
ANSWER : Hi there. Check the fuel system for any air in the fuel rail. residual air in the fuel system will cause the engine to randomly cut off. If the fuel pressure is good and there is no air in the fuel system, then I recommend changing the ignition module for a new one and not a used one. The ignition module is the trigger for the ignition spark plugs and if the module is not working properly then it will not fire the spark plugs at the right time causing the engine to stall out. I recommend seeking out a professional, such as one from Your Mechanic, to help you with your engine stalling out at idle and highway speeds.
Crank but no start. No spark or fuel – all quit at the same time
ANSWER : Hello. If the vehicle began to experience these issues after going through a puddle then it may very well be possible that one of the components may have shorted or malfunctioned due to moisture. First off, keep in mind that the fuel and ignition systems function independently of each other, which means that there may be more than one issue that is cutting off power to each of them.
If there is no spark or fuel, then the first thing I would do is check the vehicle’s fuses and relays, particularly the EFI main and ignition relays. It may be possible that one of these components has failed and is cutting off power to the vehicle’s ignition and fuel systems. If these check out, then it may be possible that the issue is wiring-related, in which case I would carefully examine the engine bay for any worn, frayed, or otherwise potentially faulty wiring. A certified technician from YourMechanic, can come to your car’s location to inspect the car’s starting problem and pinpoint the repairs needed to have this resolved.
engine cranks over but won’t start
ANSWER : Hello. Thank you for writing in. The fuel smell you are having is from the engine throwing fuel into the cylinders that is not being burned. The spark system will is likely the cause of your no start. If none of the coils are receiving power, then the issue is likely the powe’re source to the coils. Check for voltage there. If they are reciting voltage but not producing spark, then all of the coils need to be replaced. You should replace them all at the same time anyway. This keeps the wear on the vehicle even. Replace the plugs at the same time.
Spark plugs,spark wires,icm,ecm,ignition coils,replaced engine,crankshaft sensor,harmonic balancer car still misfires, wont start
ANSWER : Hi there. If your car had overheating issues before this misfiring issue began, it is quite possible that you have some internal engine damage like a blown head gasket that is the primary source of your troubles. Other damage to cam sensors and ignition timing and fuel components can also cause these issues. Before you sink another dollar in attempting repairs, I would strongly recommend having a professional mobile mechanic from our team come to your location and complete a car is hard to start inspection so they can pinpoint the root source and recommend the best course of action.
