Same here Taffy,

Swapped fuel pump from the HDi 90 engine to mine, which I KNOW doesnt cut out, my car now starts better, but she STILL cuts out. Gonna try fuel tank pump tomorrow or thursday...

yea im thinking that myself...i took leak off pipes off injectors too and nothing atall

Remove a leak off pipe and switch on ignition, you should get fuel as it primes the system...

taffy · Post by **taffy** » 22 Oct 2013, 19:48

it primes backwards thou...as in the return to the tank feeds the leak off pipes...

citroenxm · Post by **citroenxm** » 22 Oct 2013, 19:51

its all interlinked into the curcuit...

well i disconected the leak off from return line and went to start it...if there was pressure at the injectors and they wernt opening where would the fuel go?

citroenxm · Post by **citroenxm** » 22 Oct 2013, 19:58

Out of the leak offs, if theres nothing comming out, then theres no fuel getting there..

taffy · Post by **taffy** » 22 Oct 2013, 20:05

thats what i thought...must be tank pump...even thou theres good pressure there

taffy · Post by **taffy** » 22 Oct 2013, 20:06

could even have an air leak perhaps?

taffy · Post by **taffy** » 22 Oct 2013, 20:10

that would explain it wouldnt it!
i wonder how much of the fuel line i can replace with just normal fuel line?

How do you know there's good pressure there?

I'd be tempted to take the main fuel line off in the engine bay before it goes to the pump and switch the ignition on, see if it gives you anything. Obviously put the end in some sort of container to catch it. I'm not sure where it is on the Xantia, but it's on the top drivers side rear of the engine near the rocker cover on the Berlingo, this is where the AA man disconnected it to suck the petrol through when I misfuelled it. I'd imagine disconnecting it and switching the ignition on should result in fuel flow, if the pump is good.

My brother had a problem with the in-tank pump in his C5. A smack with a hammer temporarily sorted it.
