-
Caution
-
• The supply pump is sealed to maintain proper function. Special tools and testers are required when disassembling the supply pump. Disassembling the supply pump without special tools and testers will cause a malfunction.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the fuel metering valve connector.
3. Measure the resistance between the fuel metering valve terminals using an ohmmeter.
-
• If as specified, carry out the “Circuit Open/Short Inspection”.
