GENERAL INFORMATION

Places of connection of the manometer

A. On the engine of 2,7 l:
1. Fuel supply tube
2. Laying
3. A set for check of pressure
B. An arrangement of the regulator and distributor of fuel on l V6 3,4 engines:
the arrow specified a cap

PERFORMANCE ORDER
1. Implementation of the procedure described below requires the manometer for measurement of pressure of fuel with a hose calculated on pressure not less than 3 kgfs/cm2. The tip of a hose has to have a design like "banjo", i.e. be condensed with a bolt with the internal through channel.
2. Check tension on the battery, turn off a stopper of the fuel tank and execute actions a decompression of fuel system.
3. Pressure of fuel can be checked in the specified places.
4. Transfer the selector of automatic transmission to situation Park, or install the manual transmission in neutral situation.
5. Transfer the ignition key to position of ON and consider pressure. Compare to standard.
6. If pressure is higher than norm, then check purity of the return fuel pipe. If the contamination is absent, then replace pressure regulator.
7. If pressure low, then press the return hose. If pressure increases, then replace pressure regulator. Otherwise check the highway of supply of gasoline, fuel the pump the filter.
8. Start the engine and determine fuel pressure idling. If pressure differs from norm, then check a condition of a vacuum hose and the regulator of pressure (see subsection 5.3.3).
9. Stop the engine and be convinced that pressure of fuel remains at the level of 1,35 kgfs/cm2 within 5 minutes after a stop. If pressure falls down quicker, then can be the cause leak in the fuel pump, the regulator of pressure or in a nozzle.
