2000 Chevrolet Cavalier 2.2L P0303 Fault: Persistent Orange Spark and Starting Issues After Coil Pack Replacement
I recently encountered a P0303 diagnostic code on my 2000 Chevrolet Cavalier with a 2.2L engine. I replaced both coil packs as recommended, but the issue persists—there's still an orange spark observed during ignition testing. The vehicle now fails to start and produces an unusual noise when attempting to crank. Despite the replacement of components, the problem remains unresolved. I'm seeking advice on potential root causes beyond coil pack failure, especially considering possible issues with fuel delivery, spark plug condition, or engine timing related to this P0303 code.
