| 1. Performance described below procedure needs a manometer 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. In the absence of a special manometer, get the ready union of the banjo type, with internal diameter of 12 mm to which the hose with a collar from your manometer approaches. |
|
|
3. In the absence of the ready union it can be made of a bolt with carving М12х1,25 of mm. Grind off a head of a bolt and drill two openings – one through on the bolt center, and another – on the center across a bolt, being crossed with a longitudinal opening. Screw a nut and a lock-nut, having condensed a carving with a teflon tape. |
| 4. Unscrew a stopper of a jellied mouth of a tank. |
| 5. Be convinced that tension on the battery is not lower than 12 Century. |
| 6. Execute a decompression of fuel system. |
|
7. At existence on an adapter manometer, unscrew a bolt on the distributor and screw an adapter. |
|
8. An adapter made independently, screw, a rka it is shown on a photo. |
9. A manometer connect in the following order:
– in the presence of a "regular" manometer connect it to a special adapter established on the fuel distributor;
– surely establish new laying on both parties of an adapter;
– independently made adapter screw in the fuel filter, tighten a lock-nut;
– attach a hose of a manometer and fix a collar. |
| 10. Wipe the gasoline spilled from the distributor of fuel or from the filter. |
| 11. Put the lever of the selector of automatic transmission in the situation Park, or the gear shifting lever in neutral situation. |
| 12. On all cars of 1988-1994 connect накоротко conclusions In + and FP on the diagnostic socket by means of a special crossing point. |
Prevention
On cars of 1995 food giving on the fuel pump via the diagnostic socket is not provided. On these cars for reading of pressure of fuel it is necessary to start the engine.
|
| 13. Include ignition (the engine not to start). Consider the indication of pressure and compare it to the standard. |
| 14. If pressure raised, check a return gasoline pipe line. If gasoline passes through a gasoline pipe line, replace a regulator of pressure of fuel. |
| 15. If pressure lowered, press a return gasoline pipe line. If pressure increases, replace a regulator of pressure of fuel. If pressure does not increase, check the highway of supply of fuel, the fuel pump and the fuel filter. |
| 16. Remove a crossing point from the diagnostic socket, or from the socket of the fuel pump. |
| 17. Start the engine. |
| 18. Check pressure of fuel idling, result compare to the standard. |
| 19. If pressure differs from standard, check a vacuum hose and a regulator of pressure of fuel. |
| 20. Stop the engine and be convinced that pressure of fuel remains at level of 1,3 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. |
