Power Supply Circuit Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure the voltage between terminal 30 of the fuel pump relay connector and chassis ground.
3. Measure the voltage between terminal 85 of the fuel pump relay connector and chassis ground.

Specification : Approx. B+




4. Is voltage within the specification ?






Control Circuit Inspection

1. Measure the voltage between terminal 86 of the fuel pump relay connector and chassis ground.

Specification : 4 - 5V




2. Is voltage within the specification ?






Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?
