Tests W/Codes - LH Fuel Injection: Introduction
NOTE:
The 900 uses two different Fuel Injection systems, a LH Fuel Injection and a CIS Fuel Injection. The CIS Fuel Injection does not have On-Board Self Diagnostics.
If no faults were found while performing basic diagnostic procedures in BASIC TESTING article, proceed with self-diagnostics. If no fault codes or only pass codes are present after entering self-diagnostics, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e. ROUGH IDLE, NO START, etc.).
