    Default 2.2 direct fuel pump

    Afternoon,
    Does anyone know how hard it is to fit a fuel pump to a signum 2.2 direct petrol? I have seen one on ebay but need to know if im able to fit it or if it needs specialist tools, or if its in-tank or remote?

    Cheers

    Ed

    I would hold off buying 1 just yet as over the past couple of days i remember reading that vectra fuel pumps have to be programmed to the car at local dealers but i'm not sure whether it was the petrol or diesel versions

    Just hold off until u get this confirmed as i'm sure someone will be able to confirm this or not

    You might be ok as the thread i was reading was on a diesel

    http://www.vectra-c.com/forum/showth...ight=fuel+pump

    Check to make sure though.

    Also take a look at this from another thread by sundance

    (2005.06) - Signum 2003 To 2004 - Engine Type: Z22YH - High Pressure Pump, Fuel Pressure Regulator - Defective (P1191 set)



    Signum/Vectra 2003 To 2005 - Engine Type: Z22YH

    High Pressure Pump, Fuel Pressure Regulator - Defective (P1191 set)

    The customer complains that the MIL is on. P1191 us set in the ECU.

    1. High pressure pump defective, vehicle not driveable

    2. Fuel pressure regulator defective, vehicle runs in emergency operating mode

    This is caused by a defective high pressure pump or fuel pressure regulator valve. In case of customer complaint proceed as follows to verify the defective part:

    1. Check fuel feed pressure at high-pressure pump with manometer (engine running)

    Is primary feed pressure less than 3, 4 bar?

    Yes: Low pressure fuel feed failure -> check fuse, relay, intank module.

    2. Measure fuel pressure in the high pressure rail at idle by using Tech2 Datalist.

    Is fuel pressure in the high pressure rail less than 600kPa?

    Yes: High pressure pump defect, replace.

    3. Pull off connector (two-core) of the fuel pressure regulator.

    Measure the voltage of the fuel pressure sensor at 3000RPM (standing vehicle) with Tech2.

    Is Voltage greater than 1, 2V?

    Yes: Fuel pressure regulator defect, replace.

    4. Defect is not clearly allocable to one component. Proceed according to TIS 2000 service instruction.

    TIS Reference Number: E0001614

    on the end of the camshaft with fuel pipes coming off it/on to it from the fuel rail , fuel filter, tank return. Not cheap but only 20 mins to change yourself.
