    Default fuel pressure problem

    Hi,

    New to this forum, just bought an auto 05 vectra 2.2 direct design and it's immediately had problems when the engine is under strain, ie. trying to accelerate up a steep hill etc. or just fast acceleration in general. If pushed too hard the car ends up needing to be stopped and restarted.

    I took it to a local garage and the fault code came up with something to do with the fuel rail pressure fault, I think and I'm not 100% on this but the error was "P0191 Fuel Rail Pressure Sensor Circuit Range/Performance". The suggested areas were wiring, fuel pump and ECM. They suggested changing the fuel filter/fuel pump but they are really busy there and said it would take time to sort this out, which could cost big money.

    Just wondered if any of you seasoned owners/mechanics have had similar problems and could give any advice?

    Cheers!

    Similar problems that a lot of 2.2 petrol owners are having. I had similar problems to you and it was the high pressure pump - @ £552 to fix. But it could also be some thing else, less expensive.

    Cheers for the reply KC, I have looked the issue up and it seems this is the obvious problem, ie. replace high pressure pump.

    My question is, is it better to go to a vauxhall garage to get it fixed, or go with a cheaper garage which (may?!?!) be able to get and fit the part? (If this is a newbie/silly question, sorry guys, am pretty new to this!)

    I have to say its rather frustrating having to drive the car so "conservatively" if you will (ie. moterways up a hill I KNOW I can only budge it up the hill at 2-3000 revs at 60-65mph!), if I wanted to drive as such, I wouldn't have got a 2.2l car in the first place!!!

    Who knows for sure, you pays the money ...

    Personally any Main Stealer would have to be a complete last resort for me, you and others on here may feel different.

    Best advise I can give is to ask around locally and take it to a recommended reputable local garage. In my experience the locals tend to try harder, their more hungry for your business.

    Replacing the fuel pump is an incredibly simple DIY job.

    I take it this is the part I need?

    http://cgi.ebay.co.uk/Vauxhall-Fuel-...item2eaa00abdd

    Seemed about the going rate for these? Is it worth me trying to get a used one from a breakers yard, to save some cash, or is it better to just go for the £300ish new cost, it seemed reasonable enough anyway at that price?

    Hopefully this will solve the problem with the car anyhow!

    You need to make sure that your new pump is the new revised pump or you could end up replacing the same part again. At least get the proper info from VX so you know what your buying.

    I'd imagine there would be a different part number. There's plenty of info on the subject in the forum, it just might take a while separating the wheat from the chaff. Use the Search function at the top of the forum mate, but as I say its going to take a lot of reading to find the part number. Your dealer should be able to give you the new part number mate.
