Can a bad spark plug cause a fuel injector code?
Spark plug, wire, coil pack, fuel injector, vacuum leak, mechanical problem, etc, all can cause this code. Forget about the fault codes and just go about diagnosing it as you would have before OBD2. Check spark, check mechanical, check fuel delivery.

How do you diagnose a cylinder misfire?
The PCM can detect when a cylinder decelerates (an indication of a misfire), store a Diagnostic Trouble Code (DTC) in memory, and turn on the Check Engine Light. Some car computers detect misfires by measuring electrical activity [ionization] at the spark plug electrodes.
What happens if you connect spark plug wires wrong?
When one or more spark plug wires are crossed, the engine may not run, or runs roughly as the timing of fuel/air compression does not align with the delivery of the spark.
What are the symptoms of a blocked fuel injector?

Where is the correct location of the spark plug?
This device is located at top of the engine cylinder. The proper location of the spark plug provides Correct timing for Ignition. The main requirement of Spark Plug is, it must have high resistance and must have a proper gap between the two electrodes. This Gap is usually between 0.6mm to 1mm.
Where does the fuel injector go on a diesel engine?
The fuel injector is fitted on the Diesel Engine or CI Engine. (In Diesel engines don’t require any spark plug and the required heat to, Ignite the fuel is generated due to compression of air).
How does a spark plug generate a spark?
This component generates the spark with the help of DC current. This device compressed the diesel and sprayed the compressed fuel inside the engine cylinder. In the case of Spark Plug, we need to maintain it on a regular basis, otherwise, carbon will be formed over the electrode and then we face engine starting problem.
