Test J: Step 32

32) Check Continuity of POWER-to-PUMP Circuit  Turn key off and disconnect ECA 60-pin connector. Inspect connector for damaged pins, corrosion, or loose wires. Service as necessary. Install breakout box and leave ECA disconnected. Disconnect fuel pump relay. With DVOM on 200-ohm scale, measure resistance between test pin No. 8 (No. 19 on 5.0L PFI) at breakout box and POWER-to-PUMP circuit at relay harness connector. If resistance is less than 5 ohms, remove test set-up, replace ECA, and rerun QUICK TEST. If resistance is greater than 5 ohms, repair open circuit between FPM connecting splice and fuel pump relay. Rerun QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 32) to step 90). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
