2.2 direct fuel pump

[edwardabud86]

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

oh ok...yeh i will do! wasnt going to do it tonight anyhoo. Just really annoying as ive had a new ecu, swirl actuator and fuel regulator and this is the what i hope to be the final hurdle! but im running out of money! so need it done cheaply I really want my car back!

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

Check to make sure though.

Also take a look at this from another thread by sundance

This isnt the Field Remedy word for word but is the test to check if pump is faulty!!


(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

do you know where it is?

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.

had mine done 10 weeks ago you do have to have it set up on a comp,ive gone the other way fuel pump 1st then fuel rail sensor now am told it needs the regulator but hopefully that will be the end of it,make sure you goet the one for your car ie reg number,there are more than 1 for the 2.2 direct hope this helps.rick

hey thanks for the responses!

I bought one today on Ebay for £300 so not too bad! comes with 12 months garuntee too. Am going to attempt to fit it myself with my brother. i changed the regulator a little while ago before i had the new ecu! so wont need that hopefully!
Fingers crossed this is the last hurdle and i can have my car back

[rick1965]

how much was the regulator
