WARNING: This page is about a different car, the 1997 Ford Econoline and 1997 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition off. Using a voltmeter, check for battery voltage between ground and PCM terminal No. 55 (KAPWR). Turn ignition to START or RUN position. Check for battery voltage between ground and PCM connector terminals No. 71 and 97. If battery voltage is not present, power is not being supplied from EEC power relay. See CIRCUIT TEST B in TESTS W/CODES - 4.2L article.
