Start Problems, air in fuel prob.

[cog]

Has anyone experienced air getting in fuel & difficulty priming via top of filter/priming pump. Perhaps due to split diaphram etc?

Love to here,

"Yes" I assume if it diaphragm type pump that its a Mk1 and they are prone to failing. But first, just make sure that all the connections ar tight and that the filter is sealing properly to the housing. To prove it, you could very temporaly bypass the filter by connecting the two ends together. Have you changed the filter lately? a blocked filter will obstruct the flow of fuel and cause air ingress.

Hi Peter.N.

Mine is 2.5 mk 2, I have thought about bypassing, but need to prime to get fuel into pipes first.
I have the plunger type primer, and when I do try to pump it leeks a little at, or around the plunger a little.

will persevere.
many thanks, COG

Hi COG

Ah! dont know much about those, I know they are very good but have never had the courage to take one on! I think the first port of call for air ingress is the fuel heater which is bolted onto the cylinder head somewhere, they are prone to going pourous, if you havn't done so already you can also bypass that by joining the ends together. If you dont know where it is, follow the inlet pipe from the pump.

I thought all 2.5s had were electronically managed? you learn something new every day!

Hi Cog

Could find a spare 2.5 fuel filter assembly if this would help (located Winchester).

Hi Cog

When you prime the plunger should stay totally dry so I guess you have found your air leak. It cant be much of a leak as the fuel in the pipe run is sucked up and it seems to supply ok once started just leaks air in when left a while.

have bypassed filter...guess what!...she's-u-runnin
thanks peter.N.


HI, XMexc.
looks like I'm a canidate for your filter. Let me know.

has anyone else had this prob. on a 2.5?....love to know.

another question to all: my key fob has decided to stop working, despite new batteries. And anyone know how to fix broken or unnhooked boot lid cable.

GREAT!!!

Hi Cog

If you have good eyesight and are handy with a soldering iron, you may be able to repair the fob. They are prone to dry joints and components coming adrift from the circuit board. Take it out of the case and have a good look at it under a bright light and with a magnifying glass, and gently prod the components and see if anything moves. I repaired mine once and the next time couldn't and then found that the reciever had packed up! While there are still some about, see if you can get a plip and matching reciever - that's what I had to do.

The reciever is located under the glove box.

Hi Cog

Will look out a filter next time I go over the unit. E-mail me with contact details. Does your fob still flash the red light when pressed? Yes then suspect the receiver No then the fob. Have spare sets.

If the light on the fob does come on then it could be that they are out of sync. I put on here the process for resyncing them a while back. If you want it and can find it I can dig it out.

Worth a try before replacing just in case.

hello rowanmoor,

yes I should v. much like to see the resyncing procedure.

thanks,
COG

The procedure is the same as that used to reprogram the IR plips on many cars (PSA especially):

Turn the ignition to the 2nd position and then press the lock/unlock button and hold it for about 10 seconds then turn off the ignition and try the plip to see if it works.

The reason it is needed is that the RF system uses 'rotating' codes. Ie each time you press the button it sends a different code. The reciever then remembers the last one that that key used and will only accept another from that key that is within a certain number of codes from that (to allow for your pressing it when it is in your pocket).

They should in theory never get far enough out of sync to need it (excepting a new key), but if a button gets stuck it can. I am not sure what happens if it is left without a battery for a while either.

[Peter.N.]

Will this work with any plip or only the one programmed for that particular vehicle?

Hi Peter

In the case of the Mk2 Plip set it only works with the code numbered items that make up the set (2 Plips & a reciever). The code is marked on all of them but the little white stickers sometimes fall off the Plip PCB's. The code marking (combination of 5 numbers and letters) may give progamming information but if so this has never been published even to dealers. The Citroen workshop manual says that only 2 plips are supported but an ex French embassy Mk2 sold last year was advertised as having 3 Plips but I guess Citroen just wired in an extra receiver to make more Plips work on that car.
