anyone ,does it have a fuel pump in the tank

[Keithy]

no i dont think so. it self primes as you turn the engine over

Don't think there is a lift pump in the tank mate, you may need to buy a hand priming pump to get rid of any air in the pipes. Don't keep winding it over though as the pump will seize eventually due to lack of lubrication

thanks for your help lads I will try something tomorrow

I did open the water drain screw on my 2.2 DTi once. Never again...

As you found out, it lets air in and no water comes out. When I changed the fuel filter last there wasn't a drop of water in it after 2 years untouched.

I think that as there's no need to drain water in the UK as long as you use quality fuel from good places as it won't have water in it.

If you only let a bit of air in, the car should start OK after a little bit of turning over. As people say though, you've got to be careful with the DTi fuel pump...

There's definitely no electric fuel pump in the tank (you need a CDTi for that) - just the high pressure one on the engine that was to draw diesel from the tank through the filter. Dealers have an electric fuel pump they use to prime DTi's after air has been let into the fuel system. You can also get manual pumps but you'll obviously have to break the fuel pipe somewhere to put it in.

i have put a manual primer in still no joy could it be crank shaft sensor or would the spanner light be on

It could be a sensor, but if the fuel filter change is the only job you've done, then it's probably this that's causing it.

The car will run for a bit after a filter change on the fuel that's in the pump and the supply pipe from the fuel filter, but will then stall when it gets to the air in the filter. Usually though it doesn't start enough to drive anywhere - it's a few seconds at most.

Make sure that the fuel filter seals are all in place correctly so they're not letting air in. You could also try brimming the fuel filter with diesel through the screw hole in the top - some people have done this to avoid/minimise the manual bleeding//priming. I've never tried it myself.

My mother has a 2.2 dti and she ran it dry of fuel and it started doing the same as yours but hers would splutter and die but it would start again after cranking it for a while.She took it to vx and they said a faulty leak of pipe and a boost pipe were causing it so they changed them everything was fine for a couple of days then it started spluttering and died but would not start again.So went back to vx on a recovery truck and they said it was injector seals so she had that done and then my old man and i went to collect it and it died on the forecourt so it had another fuel filter fitted and has been running ok scince it still does it now and again mainly if its sitting on a slope nose up just thought id share that with you lol you may find some of it useful.Hope you get it sorted.

Stuarty I might just try a vx filter to see if it helps
