#### SERVICE PRECAUTIONS

- Do not operate the fuel pump when the fuel lines are empty.
- Do not reuse fuel hose clamps.
- Do not disconnect the ECCS harness connectors before the battery ground cable has been disconnected.
- Make sure all ECCS connectors are fastened securely. A poor connection can cause an extremely high surge voltage in the coil and condenser and result in damage to integrated circuits.
- Keep the ECCS harness at least 4 in. away from adjacent harnesses to prevent an ECCS system malfunction due to external electronic "noise.''
- Keep all parts and harnesses dry during service.
- Before attempting to remove any parts, turn OFF the ignition switch and disconnect the battery ground cable.
- Always use a 12 volt battery as a power source.
- Do not attempt to disconnect the battery cables with the engine running.
- Do not depress the accelerator pedal when starting.
- Do not rev up the engine immediately after starting or just prior to shutdown.
- Do not attempt to disassemble the ECCS control unit under any circumstances.
- If a battery cable is disconnected, the memory will return to the ROM (programmed) values. Engine operation may vary slightly, but this is not an indication of a problem. Do not replace parts because of a slight variation.
- If installing a 2-way or CB radio, keep the antenna as far as possible away from the electronic control unit. Keep the antenna feeder line at least 8 in. away from the ECCS harness and do not let the 2 run parallel for a long distance. Be sure to ground the radio to the vehicle body.
