Test J: Step 23
23) Check Continuity of Fuel Pump Monitor (FPM) Circuit Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector. Inspect connector for damaged pins, corrosion, or loose wires. Install breakout box and leave ECA disconnected. Disconnect fuel pump relay. Set DVOM on 200-ohm scale and measure resistance between test pin No. 8 (No. 19 on 5.0L PFI) at the breakout box and POWER-to-PUMP circuit at the fuel pump relay vehicle harness connector. If resistance is less than 5 ohms, replace ECA, remove breakout box, reconnect fuel pump relay and repeat QUICK TEST. If resistance is greater than 5 ohms, repair open circuit, remove breakout box, reconnect all components and rerun QUICK TEST.
