Remove
1. Remove acoustic cover.
+ENGINE - K SERIES KV6, REPAIRS,
Cover - engine acoustic.
2. Position absorbent cloth beneath fuel rail.
WARNING: Fuel vapour is highly flammable
and in confined spaces is also explosive
and toxic. Always have a fire extinguisher
containing foam, CO2 , gas or powder close
at hand when handling or draining fuel.
3. Up to 03MY: Remove nut and bolt securing coil
and position coil aside.
4. Connect adaptor LRT-19-006, to pressure
gauge LRT-19-004 .
5. Remove schraeder valve cap.
6. Connect pressure gauge to fuel rail schraeder
valve.
7. Start engine. Pressure at idle = 3.4 bar. If
pressure is below 3.4 bar, suspect the following
in order: fuel hoses, filter, regulator and pump.
Refit
1. Stop engine.
2. Disconnect pressure gauge LRT-19-006 and
adapter LRT-19-004 from fuel rail.
3. Up to 03MY: Fit and tighten nut and bolt
securing coil.
4. Fit acoustic cover.
Fuel system - pressure test - K1.8
Check
1. Disconnect battery earth lead.
2. Position absorbent cloth beneath fuel pipe to
catch spillage.
WARNING: The spilling of fuel is
unavoidable during this operation. Ensure
that all necessary precautions are taken to
prevent fire and explosion.
3. Disconnect fuel pipe from inlet manifold.
4. Connect adaptor LRT-19-010 to LRT-19-004
pressure gauge.
5. Connect adaptor LRT-19-010 and pressure
gauge LRT-19-004 to manifold and fuel pipe.
6. Connect battery earth lead.
7. Start engine. Pressure at idle = 3.5 bar ± 0.2
bar.
8. Release clip, disconnect and plug fuel pressure
regulator vacuum hose.
9. Start engine. Pressure at idle = 3.0 bar ± 0.2
bar.
10. Stop engine. If pressure is out of tolerance
suspect the following in order: fuel hoses,
regulator, filter and pump.
11. Remove plug, reconnect vacuum hose and
secure hose with clip.
12. Disconnect battery earth lead.
13. Disconnect pressure gauge LRT-19-004 and
adaptor LRT-19-010 from fuel pipe and
manifold.
14. Disconnect adaptor LRT-19-010 from LRT-19-004
pressure gauge.
15. Connect fuel pipe to manifold.
16. Connect battery earth lead.

The fuel delivery pressure to the high pressure pump is usually around 350-400kpa,engine running monitored by testbook on live data.If the pressure drops below this the performance suffers.Darrnw said:
