1998 Acura 3.5 RL PUMP RELAY (3.5 RL) owners of the installation manual. The relay for the fuel pump is located in the front part of the carcase. Turn the key to the start position. If the engine starts, go to the next step. If the engine cannot start, go to the fuel PUMP RESISTOR (3.5 RL). 2. Turn off engine and ignition of. Measure the voltage between the ground and PCM 12-pin connector Terminal No. 4 (green wire). If there is voltage of the battery, go to the next step. If there is no voltage of the battery, go to step 4). 3. Start the engine and operate at 3000 rpm with no loads and transmission in Park or neutral, while a fan of radiator, which lights up. Allow the engine to stay at least one minute. Turn off the engine. Disconnect the vacuum hose no. 21 of the vacuum manifold. Apply 8-12 v. Hg (27-40 kPa) vacuum manifold absolute pressure (map) sensor. Start the engine and run at 6500 rpm with no loads and transmission in Park or neutral. Measure the voltage between the ground and PCM 12-pin connector Terminal No. 4 (green wire). If there is less than one Volt, fuel pump relay circuit is good. If one Volt or more, substitute known good PCM, then recheck. If symptom or the mark will disappear, replace the original PCM. 4. turn off the ignition. Disconnect the PCM 26-pin and 12-pin connectors. Unplug the fuel pump relay 4-pin connector. Using a fused jumper wire, connect the fuel pump relay connector terminals No. 2 (red-white wire) and no. 4 (green wire). Shall be switched on. Measure the voltage between the ground and PCM 12-pin connector Terminal No. 4 (green wire). If there is no voltage of the battery, go to the next step. If there is voltage of the battery, replace the fuel pump relay. 5. To remove the jumper wire.
