Safety precautions when working with the injection system

Do not start the engine with loose terminals on the battery.

Do not disconnect the battery while the engine is running.

When charging the battery from the charger, disconnect both battery terminals from the car's on-board network.

Do not use a quick charger to start the engine.

At temperatures above +80°С (drying after painting) remove the electronic control unit.

Do not disconnect or connect the ECM connector with the ignition on.

Turn off power to the fuel pump relay when checking compression.

The power system is pressurized, so the pressure must be relieved before replacing parts of the system. If the engine has not been running for several hours, the pressure drops by itself.
