High Pressure Line (From The High Pressure Fuel Pump To The Fuel Injector); Fuel Tank Removal/Installation [L3 With Tc] - Mazda CX-7 2007 Workshop Manual

6. Turn the lever parallel to the hose of the SST as shown.
7. Connect the vacuum hose to the intake manifold that connecting to the brake booster.
8. Connect the negative battery cable.
9. Start the engine and let it idle. Measure the fuel line pressure.
• If not as specified, inspect the following:
Zero or low
— FP circuit
— FP
— Fuel line (clogged)
— Fuel leakage inside pressure regulator
High
— Pressure regulator for high pressure cause
Fuel line pressure
410— 490 kPa {4.2— 4.9 kgf/cm
10. Turn the ignition switch to the LOCK position.
11. Measure the fuel hold pressure after 5 min.
• If not as specified, inspect the following:
— FP hold pressure
— Fuel injector for leakage
— Fuel line for improper routing, kinks or leakage
Fuel hold pressure
More than 230 kPa {2.3 kgf/cm
12. Complete the "BEFORE REPAIR PROCEDURE".
(See01-14-4 BEFORE REPAIR PROCEDURE[L3 WITH TC])
13. Disconnect the vacuum hose from the intake manifold that connecting to the brake booster.
14. Disconnect the SST.
15. Connect the quick release connector. (See01-14-19 QUICK RELEASE CONNECTOR REMOVAL/
INSTALLATION[L3 WITH TC].)

High Pressure Line (From the High Pressure Fuel Pump to the Fuel Injector)

1. Inspect the fuel pressure sensor. (See01-40-35 FUEL PRESSURE SENSOR REMOVAL/INSTALLATION[L3
WITH TC].)
2. Inspect the high pressure fuel pump. (See01-40-35 FUEL PRESSURE SENSOR REMOVAL/
INSTALLATION[L3 WITH TC].)
