Diagnosing LR044427 Failure Confidently
Before replacement, conduct these tests to confirm pump failure:
Fuel Pressure Test: Connect a gauge to the Schrader valve. Compare readings to factory specs (e.g., 58–64 PSI for many applications).
Current Draw Test: Use an amp clamp. Excess amperage (>8–10A) indicates pump motor strain.
Voltage Check: Ensure 12V reaches the pump connector during cranking.
