* Engine temperature: A cold engine requires more fuel to start.
* Battery voltage: A weak battery will result in less fuel being delivered.
* Fuel pressure: Low fuel pressure means less fuel will be injected.
* Cranking speed: A faster cranking speed generally means more fuel is needed to ignite properly.
* Computer settings: The engine's computer (PCM) adjusts the fuel delivery based on various sensor inputs.
You can't measure this directly without specialized equipment. Instead of focusing on the precise amount of fuel, it's more practical to address potential starting issues by checking the basics:
* Battery: Test the battery's voltage and cranking amps. A weak battery is a common cause of starting problems.
* Fuel pump: Listen for the fuel pump's prime when you turn the key to the "on" position (but don't crank). A weak or failing pump can also prevent starting.
* Fuel pressure: This requires a fuel pressure gauge and is best checked by a mechanic.
* Spark plugs and wires: Check for wear or damage.
* Air filter: A clogged air filter can restrict airflow.
* Sensors: Faulty sensors can disrupt the engine's computer's ability to control fuel delivery.
If your S10 is having starting problems, focus on diagnosing these potential issues rather than trying to quantify the exact amount of fuel injected during cranking.
