There’s nothing quite as troubling as your engine not starting.
Unfortunately, It’s also one of the most common types of engine problems.
There’s almost no driver who hasn’t experienced the sinking feeling of the engine not starting.
Before your car would not start did you notice anything out of the ordinary. Was there a low power or a check engine light? Consequently, This could aid in the troubleshooting and diagnosis process.
All engines require three things to start and run: spark, fuel and compression. As a result, If any one of these isn’t there, you aren’t going anywhere.
There Are Two Basic Types Of Engine Not Starting Conditions
No crank / No start – You don’t hear the engine moving at all. You might hear a click or buzz but other than that, nothing.
You turn the key to the “Start” position, but the engine won’t crank. In addition, A single click or repeated clicking is all you hear. Hence, A weak battery or poor connection at the battery terminals could be the cause. Also, Sometimes a battery cable can get corroded inside causing the same problem.
Also, In some cases a bad connection between the negative battery cable and the engine (bad ground); can cause the same symptoms. Of course, there could be other reasons but most often this happens; when there is not enough electric current for the starter motor to turn over the engine.
If the battery is OK and the battery terminals appear clean and not corroded it could be:
- Starter solenoid
- Battery cables
- Starter motor
Crank / No start – When an engine cranks, you can hear it spin, but the engine doesn’t catch or run.
Some of the most common reasons an engine fails to start include:
- Engine is flooded
- Bad fuel pump or fuel pump relay
- Water in fuel
- Bad mass airflow sensor
- Bad crank or cam sensor or wiring
- Problems with the engine computer (PCM) or PCM circuits
- Faulty ignition coil pack
- Incorrect timing
- Low compression in the engine
So, Anytime you are having a problem with your vehicle always try to narrow down the list of possible issues. As a result, saving you time and money down the road. Finally, Less things to check can make for a faster and cheaper repair.
