1. Depressurize fuel system.
2. Disconnect the battery from weight. Disconnect the fuel highway about the engine.
3. Establish in a gap a tee with the manometer.
4. Start the engine and check fuel pressure. Before check disconnect the vacuum distributive valve. The measured pressure on engines 4ZD1 and 4ZE1 at the disconnected and muffled vacuum hose of the regulator of pressure has to be 2,65 atm. If to attach a hose idling, then pressure has to become equal 2,2 atm. On 6-cylinder engines pressure measured after the fuel filter has to be within 0,56–0,8 atm.
