WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2000 Isuzu VehiCROSS, 2000 Isuzu Trooper, 2000 Isuzu Rodeo, 2000 Isuzu Hombre, and 2000 Isuzu Amigo. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition on. Using a voltmeter, backprobe PCM harness connectors. Check for battery voltage between PCM ignition power terminals and ground. See PCM POWER CIRCUIT TERMINALS table. If battery voltage is not present, check IGN fuse and fusible links. If fuse is okay, check for an open in wire between battery and ignition switch, and between ignition switch and PCM terminal. If okay, check for a defective ignition switch.
