WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1998 Acura Integra, 1998 Acura 3.5RL, 1998 Acura 3.2TL, 1998 Acura 3.0CL, and 1998 Acura 2.5TL. However, it is still accessible from the selected car via links, so may be relevant.
Backprobing, measure voltage between PCM 32-pin connector terminal No. 24 (Blue/Red wire) and the PCM 25-pin connector terminal No. 20 (Brown/Black wire) with ignition switch in START position. See Figure. If battery voltage is present, starter signal is okay. If battery voltage is not present, inspect STARTER SIGNAL fuse No. 9 (7.5-amp) located in underdash fuse/relay box. If fuse is okay, repair open in Blue/Red wire between PCM 32-pin connector and fuse No. 9. If fuse is blown, repair short in Blue/Red wire between PCM 32-pin connector and fuse No. 9 or PGM-FI main relay. Replace fuse.
