  A:

  To execute fuel pressure test, you are required to have a fuel pressure gauge and adapter set. Start with a pre-flight inspection: unscrew the fuel filler cap and, with an assistant turning the ignition key ON while you hear the fuelling pump priming, a whirring sound will be heard. In case of no sound, examine the fuel pump fuse; if-blown, replace it and observe its intermittent blowing. If so the circuit must be evaluated further, and the battery voltage should be checked on the fuel pump relay connector. Should there be voltage and the relay operate, inspect for voltage at the fuel pump electrical connector with the engine cranked. If voltage is no present check the fuel pump circuit; if voltage is present and the ground circuit is good replace the pump. In the operating pressure check, discharge the fuel system pressure and . Connect the fuel pressure gauge to the fuel rail depending on the type of the engine of the car in use. Connect back the negative terminal of the battery and cranking the engine, observe the fuel pressure at idle condition. For 2.2L, 2.6L and 3.2 L engines remove the vacuum line to monitor pressure fluctuations. If pressure is low, clamp the fuel return line; if pressure goes up, the regulator is bad. If pressure is high, stop the engine and shut the return line; look for obstructions. For some particular engines, check the pressure changes with vacuum applied with the help of the hand-held vacuum pump at the fuel pressure regulator. Ensure that vacuum is present at the regulator with the engine running; Lack of it call for checking clogs and leakages. If vacuum is satisfactory, change the regulator. Last and being sure that the ignition is off, check the pressure: when pressure is zero its possible that the fuel lines, regulator, injectors or pump is leaking.
