If it becomes necessary to remove certain parts of the injection system, the following precautions should be taken to avoid injury to yourself or damage to the system itself.
- people with pacemakers are not allowed to work on the injection system;
- do not touch the ignition system wires while the engine is running or when the engine is started with the starter;
- it is not allowed to disconnect the wires of the injection and ignition systems when the ignition is on. In such cases, it is recommended to disconnect the battery;
- to turn the engine over with the starter, connect an auxiliary wire to the middle wire on the ignition coil, and attach the other end to the ground (-);
- when starting the engine from an auxiliary source, the engine can be rotated for no more than one minute with a maximum voltage of 16.5 V supplied;
- when washing the engine, the ignition must be turned off;
- when carrying out welding work on the body, it is recommended to disconnect the battery;
- when towing a vehicle due to ignition problems, disconnect the power wire from the ECU to avoid damaging it.
