Places of accession of a manometer

A.Na engine of 2,7 l:
1. Tube of a supply of fuel
2. Laying
3. A set for pressure check
V.Raspolozheniye of a regulator and the fuel distributor on engines of V6 3,4 l:
the arrow specified a cap

1. Performance described below procedure needs a manometer for measurement of pressure of fuel with a hose, calculated on pressure not less than 3 kgfs/cm2. The tip of a hose should have a banjo type design, i.e. be condensed with a bolt with the internal through channel.
2. Check tension on the battery, unscrew a stopper of a 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 the situation Park, or establish a manual transmission in neutral situation.
5. Transfer the ignition key to the situation ON and consider pressure. Compare to the standard.
6. If pressure is higher than norm, check purity of a return gasoline pipe line. If the contamination is absent, replace a pressure regulator.
7. If pressure low, press a return hose. If pressure raises, replace a pressure regulator. Otherwise check the highway of supply of gasoline, fuel the pump the filter.
8. Start the engine and define pressure of fuel idling. If pressure differs from norm, check a condition of a vacuum hose and a pressure regulator (see subsection 5.3.3).
9. Stop the engine and be convinced that pressure of fuel remains at level of 1,35 kgfs/cm2 within 5 minutes after a stop. If pressure falls down quicker, the reason can be leak in the fuel pump, a regulator of pressure or in a nozzle.
