Fuel pump faults on the MG ZT 120 1.8 petrol

[topgeezer]

After having problems starting my car last week i called the RAC out who confirmed to me that i had a problem with my fuel pump. With this advice i took my car to local garage who have since informed me that after speaking to rover there are major faults on the fuel pumps of these cars. Can anyone give me any advice on these problems and ideas on repairs and costs.
Thanks, Paul.

Hi Paul and welcome to the club,

The normal fault is NOT the fuel pump but the fuel filter which can unscrew.
Fix is to gain access, screw it together and fit a clip so it wont happen again.
Takes about 30 minutes tops and the clip costs about £8 from an X Part dealer.

As a filter coming unscrewed gives low fuel pressure the problem is sometimes confused with pump failure which in fact is pretty rare.

This link will take you to a number of 'How To's' - you want the second from bottom in the left column called Petrol Fuel System Failure.

Thanks for your quick response with this matter, i will pass this information on to the garage, if they have already tried this solution is there any other problems i need to be aware of? The rover dealership indicated that there is a fault with the pump itself but were reluctant to say more unless we took the car to them? Is there any known faults with the pump?
Thanks again, Paul.

as above,
I was told by RAC I needed a new pump but it was fuel filter which had unscrew.

No, not as far as I know. As I said in first post problem with fuel filter (or as an MGR dealer may refer to as Fuel Module) is common but problems with the actual pump (a different part to the filter and located on the drivers side of the tank) are rare.

Diesel engined cars can have a problem with fuel pumps but not petrol cars.

If you are at all handy with tools checking the fuel filter and screwing it up again is well within average DIY abilities.

If you can do a search on this forum (using search button at the head of this page) you will find numerous posts under 'fuel filter' for petrol cars but if you try 'fuel pump' only diesels will pop up.

By the way a new filter unit can cost £220 to £250. Dont be persuaded to replace until you are sure someone has checked the existing filter for tightness.

Approximately where are you located??. If we knew might be able to suggest a MG Rover specialist.

I concur with David, the fuel filter is the starting place to look. AFAIK there were two filter types used, the later one was roughly £30 to £40 when I had problems with mine. Before replacing the filter unit, check the rubber O rings that seal the filter inside, if one has split then the fuel system will not hold pressure (happened on mine). I think that they can be replaced as part of a fuel filter service kit which is a lot cheaper than replacing the whole filter housing.

Fitting the fabled Orange Clip is ESSENTIAL. (Part Number WJC000230 from Rimmers. They charge around £8 including delivery.) If this isn't done the filter will unscrew again, probably in a relatively short time.

Thanks all for your responses, i will check the filter and hopefully this will be the end to my problems. I will let you know in a few days once the problem has been fixed.
many thanks, Paul.

Hi All,

What a great site. My 2003 R75 Connosseur died while my wife was driving it and google led me here. I printed the instructions on how to rectify the problem and bingo.... back in action.

Thanks again,

Noel

Hi all,

I have a 75 1.8t and it will not start i had heard about the filter unscrewing and hoped it was that but i have taken the fuel line off the injectectors and when u turn the key to engage the fuel pump fuel is there??? so i had kind of ruled that out! unless as i read here it could be the fact there is low pressure.. Please any advice would be appreciated
Many thanks

your :welcome: to the info and the club, why not turn your name red for £10 a year and get more out of the club and help keep it going.
you dont have too.we are always happy to help for free.

The engine won't start unless fuel is delivered at the correct pressure. Your problem may not be FFS, but it has all the usual signs. To eliminate the filter from the equation, I fully recommend fitting the FOC and taking things from there. There are HowTos available on accessing the fuel tank hatches (rear seat removal) and dealing with the filter module/seals/etc. Details on the FOC are on a sticky at the head of the opening page.

I had the same problem with my ZT 1.8 2003 and a friend and I tried to fix it as per the instructions on here, although it didnt work the imformation was helpfull. In actuall fact my fuel return pipe had broken slightly and a small peice had been pulled into the fuel pump. Once the blockage was cleared and a new peice of pipe put in it started first time. Just another thing to check if you have this problem.

ive got this very same problem just now -- how do you remove the white filter unti without making a custom tool?

cheers

[Fusilier]

If you need a new fuel filter and orange clip, I have got a brand new one for sale. Purchased it two weeks ago, as I had a similar problem, and it turns out that my fuel filter is the metal one, and does not use these parts. My mechanic checked the car over, he was doing other jobs for me (new back plates)

So I still have it for sale

To purchase new will cost you around £65 plus postage. I am selling it for £50, with postage included

It would help if you put your location, you never know another member might be just around the corner and can help you.

Most people unscrew the locking ring using a hammer and a screwdriver as a drift. Same with refitting it.

The filter need not be changed, they are a lifetime use part. all you need is the Fabled Orange Clip from Xpart/Rimmer or ebay.
