Reinstall the PGM-FI main relay 2. Turn the ignition switch ON (II). Measure voltage between ECM/PCM connector terminal E10 (E1*) and body ground. ECM/PCM CONNECTOR E (31P) Wire side of female terminals Is there battery voltage? YES - Go to step 12. NO - Replace the PGM-FI main relay 2. Turn the ignition switch OFF. Reconnect ECM/PCM connector E (31P). Turn the ignition switch ON (II), and measure voltage between ECM/PCM connector terminal E10 (E1*) and body ground within the first 2 seconds after the ignition switch was turned ON (II). ECM/PCM CONNECTOR E (31P) Wire side of female terminals Is there battery voltage? YES - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/PCM. NO - Go to step 15.

Turn the ignition switch OFF. Remove the rear seat cushion (see page 20-237). Remove the access panel from the floor. Measure voltage between the fuel pump 5P connector terminal No. 5 and body ground within the first 2 seconds after the ignition switch was turned ON (II). FUEL PUMP 5P CONNECTOR Wire side of female terminals Is there battery voltage? YES - Go to step 24. NO - Go to step 19. Turn the ignition switch OFF. Remove the PGM-FI main relay 2.
