Integra & 3.2TL
Measure voltage by backprobing between PCM 32-pin harness connector terminal No. 24 (Blue/Orange wire, Blue/White on Integra) and PCM 25-pin harness connector terminal No. 20 (Brown/Yellow wire, Brown/Black on Integra) with ignition switch in START position. See Figure . If battery voltage is present, starter signal is okay. If battery voltage is not present, inspect fuse No. 13 (7.5-amp) in underdash fuse/relay box. If fuse is okay, repair open in Blue/Orange wire (Blue/White on Integra) between PCM 32-pin harness connector terminal No. 24 and fuse No. 13 (7.5-amp). If fuse is blown, repair short in Blue/Orange wire (Blue/White on Integra) between PCM 32-pin harness connector terminal No. 24 and fuse No. 13 (7.5-amp) or PGM-FI main relay. Replace fuse.
