One detail I missed, before rethreading the pipe back thro original route I plugged the end to prevent leakage.

In Topic: Changed Fuel Filter, Now Have Air In System And Will Not Start

20 May 2014 - 09:55 AM

Problem solved without trip to garage.
Spent some time looking thro forums etc last night and came up with a plan of action. These are the things I did.

1. car was up on wheel ramps at front. My drive slopes down so this meant the car was actually level but decided to take of ramps and therefore car now lower at front which possibly may help fuel flow.
2. Checked issue of orings misplaced in feed pipe to filter, was ok.
3. Disconnected pipe leading to high pressure pump at filter end and then unthreaded from other components (except for last bit near pump as too difficult). This allowed me to hold the pipe near vertical and fill properly using tube and funnel eg all air bubbles out.
4. Reconnected back to filter.
5. With feed pipe to filter off, filled up using syringe ( from children's medicine). Filled to very top and also allowed to bleed out of the small bleed screw on top. Replaced feed pipe.
6. Turned ignition on leave for 10 secs then off, did this about four times

On trying to start (according to manual 10 secs max then wait 30 secs!!) it fired 2nd time but then died and my heart sank. But about 4th time it fired ok and then ran ok. So removed pipe to pump again and rethreaded thro original route. Then tried to start and it did not fire after two attempts. Removed feed pipe to filter, filled again with syringe and it then started about 2nd time and ran ok. Note using 2nd car runing and linked with jump leads for all the starting action.

Now I cannot say which of these actions were useful or which were not, but together they appear to have worked. It is of course possible that only one of the actions played any role, but which one? From all the other comments here I would suggest that the first thing to try is filling the filter with a syringe. I thought my filter was full but it took quite a bit to top it up. Also important to be very careful fitting new seal and !Removed! top of filter back on correctly.

Many thanks for all your advice.

Just thinking about options, so far I have not removed the filter to high pressure pump pipe at the pump end. It is not obvious how this connection is made, can anyone give any instructions for removing the pipe at this end, is it a quick coupling type ?

Note sure what you mean by genuine, but recognised make (Alco Filters) from local motorist shop and both old and new filter had same number marking.
One thing I failed to mention was that I believe when I first replaced the filter element, I did not screw the filter top back correctly. I believe this to be true because when I was trying to suck fuel from the exit port, it felt as if I was just sucking air. I then took the filter top off and screwed it back on again carefully and felt happier about the tightening action. Sucking then produce fuel and not a continual flow of air. Maybe trying to start the engine in this initial condition caused extra air intake and has created this problem.
Looking at the Focus manual I see when using the special ford pump connected on the infeed side of the filter, you disconnect the flow pipe at the end connected to the HIGH PRESSURE pump and use the special ford pump to develop good clean flow at this position.
Again I feel my problem is not filling the filter but filling the pipe between the filter and the high pressure pump. It seems this is also the area that the special ford pump works upon.
