Install the nozzle of the cold start

Install the nozzle of the cold start
1. Install the cold start injector with a new gasket. Secure the nozzle with two bolts. Tightening torque:
4A-FE. 9.3 Nm
4A-OE 7.4 Nm
3. Connect the nozzle.
4. Connect the (-) wire to the negative-terminal of the battery ba-tarei.
5. Check for any leakage of fuel through the connection.
The differential fuel pressure
Checking the engine
Check fuel pressure (see "Checking the fuel pump").
Removal of the regulator
1. Disconnect the (-) wirefrom the negative-terminal of the battery.

Check injectors on the engine
1. Check the formula ¬ sunok.
Check the force NOCs to ear, a) the engine is running or when it is turning the starter with the help of phonendoscope make sure the ear (the sound of fuel injected) in the performance of nozzles, making sure that the frequency vpry Skov ¬ ¬ rotation proportional to the frequency absorption the engine crankshaft.
b) In the absence of phonendoscope can check serviceability ¬ sion jets, touching them with your finger or a screwdriver. In the absence of sound or not his character ¬ usual check the wiring, connector, nozzle, additional nozzles ¬ tively the resistance or the presence of a control signal from electronic control unit.
2. Check the resistance of the nozzle.
a) Disconnect the injector.
b) Using an ohmmeter, measure the resistance of the nozzle.
The nominal value of the resistance of the nozzle ¬:
4A-FE and 4A-OE without flow
air "2.3 ohm
4A-FE and 4A-OE with flow
the air. "13.8 ohms
