Injector Diagnosis Precautions.

When diagnosing a misfire or suspected injector malfunction, it is important to determine where the fault possibility may lie.

That is - The injector relies on:

• Correct fuel pressure and flow.
• Correct activation from the ECU. “Injection duration” monitored by a suitable scanner or oscilloscope can quickly identify if the injector ON period is correct.
• No internal injector fuel restrictions. (Dirty/blocked injectors).
• Any harness /wiring problems causing intermittent or hard faults.
