What does it mean when your car turns over with no spark?
“Turn over with no spark” typically means the engine will crank over, but the ignition system is not functioning. Normally, diagnostics have been taken far enough to eliminate the possibility that the engine is not getting fuel.
What to do when your engine has no spark?
Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.
Why does my car not start when I crank the engine?
The crankshaft position (CKP) sensor monitors the position or rotational speed of the crankshaft. If the crankshaft position sensor has failed completely, and isn’t sending a signal to the (ECU) at all, then the computer won’t send any fuel to the injectors. This will leave you unable to start the car.
What causes a car to not run at all?
In extreme cases the (PCM) may have failed. In some cases, a (PCM) problem will cause the vehicle not to run at all. The (PCM’s) functions include positioning the crankshaft and controlling the ignition spark and timing.

What does it mean when your engine turns over but won’t start?
When your engine turns over but won’t start, it means the engine is having a hard time creating a spark, producing compression, or receiving fuel. If you hear the engine turning over, the problem has to do with the starting motor system, not the engine itself.

What makes the spark on a lawn mower?
If you have a engine that is rated under or about 20 horse power your spark is probably generated by what is called a Magneto. If you have a larger engine you may have actual coils like your car and a crank positioning sensor.
What should I do if my engine won’t start?
You should see a bright spark jumping the gap in the spark tester. If you don’t see a spark, repeat the test. This time, adjust the spark tester to 30KV. If you still don’t see a spark, repeat the test and set the tester to 10KV. If this time you see a spark or no spark, you have a problem with the ignition system.
Is it possible for an engine not to turn over?
Although the engine not turning over is obvious—since the crankshaft is not rotating—the symptoms may manifest in different ways, depending on the source of the problem.
Why does my car not start when I Turn on the ignition?
In ignition systems with a single coil and distributor, a bad coil or a cracked distributor cap or rotor can prevent the spark plugs from firing. On multi-coil, distributorless ignition systems and coil-on-plug systems; one coil failure may cause an engine to misfire, but it won’t prevent it from starting. What’s causing the no-start?
Why does my car engine not start when I turn it over?
The source of the problem could be a mechanical fault, or a faulty component in other systems. No start when the engine turns over can be a number of issues; but you need to start somewhere.
What’s the difference between no start and no crank?
It’s important to know that a no crank and a no start condition are not the same thing since this article only concentrates on testing a no start condition. In layman’s terms, a No Start Condition means that your vehicle’s starter motor is cranking the engine but the engine is not starting.
