Fuel Pump Ballast Resistor Relay: Testing and Inspection
Fuel Pump Resistor Relay Testing:
1. Remove air cleaner and air flow meter if necessary to access relay.
2. Unplug relay connector and check resistance across terminals as follows:
TERMINALS RESISTANCE (OHMS)
a - b ... 0 ohms
c - d ... 60 - 92 ohms
e - f ... 0.70 - 0.94 ohms
If not as specified, replace resistor relay.
3. Connect power to relay terminal "c" and ground relay terminal "d", to energize relay.
^ Resistance between terminals "a" and "b" should go to infinity (no continuity) when relay is energized. If not, replace resistor relay.
