[Terry172]

Have done a search for injector and couldn't find how to replace the fuel injector so if anyone can be kind enough to tell me it will be appreciated

Cheers

your car has 4 mate, they are located under the funny metal cover at the front of your engine (the one that gets in the way when removing your oil filter lol)

you remove the two nuts holding this on, undo the clips that hold the wiring and pipes for the rail,undo 2 further nuts, then from memory you pull the whole rail out,(it fits into the lower plenum) then remove the offending injector from the rail


What problem do you have?

Disconnect the fuel pump and start the car a few times until it won't start to depressurise the rail would be a good idea to start with unless you've got a petrol bathing fetish or something.

Cheers for the replies ...BMH do I just disconnect the wire under the back seat or do I pull the relay in the engine bay?

http://www.cliosport.net/forum/showthread.php?t=465109 that's the problem I am having mate and now I have plugged the diagnostics in I am getting a fault reading: Injector 4 fault and when the car is running I get the same fault but another one says Injector 4 open circuit fault. I am hoping it's just a lose connector and with a clean it will be ok again but if not then I will have to replace the injector. Cheers for the reply and info mate......can I get to the connectors on the injectors without removing anything to check them?

Can do either tbh whatevers easiest, you'll be surprised how long it'll run without the pump running if its primed recently. So deffo try starting it 3 or 4 times after it cuts out the first time.

Yes you can see the injector connectors easily once the fuel rail guards off.

 

[Russ_16v]

if cleaning them doesnt work, you can send yours away to be chemically cleaned

also try swapping it with the injector next to it, see if the fault changes to that injector, this will make sure its the injector at fault not a wiring break

hurts doesnt it :dapprove:

i had fun putting them all back in 2nd hand 1s and the clips are so fun read my story mate new pump injectors and sparks u think you had it bad !!?

 

[Terry172]

Cheers for all the replies

Is there anyway I can check the connections without having to take anything apart first as in the clips on the ends before I actually take things apart to check the injector itself?

Also when looking at the car face on (drivers side is on the left) how are the injectors labelled? 1-4 drivers side to passenger side or 4-1 if that makes sense?

Okey doke I will make sure to remember this unless I decide not to tackle the task lol.

Thanks for the help all

Off topic, but what is that for???

Had to remove mine but when it came off, I couldn't see any/much use for it.....

Fook I know #4 was going to be the other end (drivers headlight side) as that's the tighter end to see anything without taking anything off

If you have a front end shunt it won't break the plastic fuel rail and spray petrol everywhere. So personally i'm under the opinion its best to leave it on .

I put it back on, just had to remove it to get to the oil filter. Should have made that clear in my original post.

Was just curious, thans for the info.

 

[bmh.01]

Quite a few peeps seem to have removed them for xyz reasons and i'd say its best left on imo. Its gotta come off to get the oil filter off without seriously struggling like you do with the meg and the inlet fanimolds in the same place and obviously not so easily removable

How do you get that metal block off as I can't get a tool in the holes at the front to undo the 3 bolts e.g. this is one of the holes below




then i take it I have to undo the bolt below and 1 the other end to get the fuel rail off?



Is that a glimpse of the injector I can see just to the left of that bolt (copper shine)?

10 or 13mm socket (i can't remember it varies between rs's and cooking models) on a 3" extension up the two lefthand holes to get the nuts off.

Thats the clip that retains the injector onto the rail but near enough yes. Its a steel clip its just rusted.
