octuford Posted October 26, 2017 Share Posted October 26, 2017 Hello All, Just joined this forum , hope to find some answers to a problem with my daughters 1.6 tdci 2011 plate ford titainium focus , I used to work for a fleet operator who ran lots of ford escort vans and knew then inside out but that was before the engine management systems came into common use I need some advice about it randomly not starting and sometimes cutting out when engine revs drop at junctions . When it will not start a "Engine Malfunction " lights up on dash . After three or four tries at starting sometimes it will start but only when the "engine malfuntion " light does not come on. There are no trouble codes shown with a generic code reader and/or the built in TEST method in the dasboard. When first encountered the code reader said "fuel system not ready" . ( Fuel filter was changed about 4 months ago.) Spoke to a recovery mechanic who thought in tank fuel pump may be the cause or fuel pump relay. Cant find a ref to fuel pump relay, Found references to fuel pump /sender unit in the tank, but dont know if this has one as there is no pump noises when switching on ignition . May be faulty but never hear it when it starts normally. The engine runs well once it is going but its getting it going is the problem. Is there any sensors that go faulty now and again that can cause this problem?. High pressure fuel sensors? any suggestions wil be gratefully recieved Quote Link to comment Share on other sites More sharing options...
isetta Posted October 26, 2017 Share Posted October 26, 2017 not sure if it has pump in tank. I had a fiesta with 1.6tdci engine and I am pretty sure it had no pump in tank and that is why it was a complete ba**ard to get it going again after changing fuel filter. the high pressure fuel pump driven by timing belt was the only pump I think and this had to suck the fuel all the way from tank which it could not do until all air bled out Quote Link to comment Share on other sites More sharing options...

If it had a pump in the tank then it would bleed easily ,... . yet on Fleabay there are fuel senders unit with a pump built into it .? My old berlingo does not have a lift pump before the hp (injector) pump, it relies on the internal pump suction in the hp pump to pull up the fuel. It can be difficult to start after a fuel filter change too. The quest continues ! Quote Link to comment Share on other sites More sharing options...

I think Ill replace the fuel filter and see what happens then , then the lift pump and fuel filter can be ruled out as the cause. I see that some of the forum like the elm327 scanner with forescan you can read a lot more than the one we have at the moment , Good or bad ?

Good, once purchased and setup correctly it saves you a minimum £50 every time you use it and don't have to use a garage. Quote Link to comment Share on other sites More sharing options...

isetta Posted October 27, 2017 Share Posted October 27, 2017 I got my code reader here https://tunnelrat-electronics.fwscart.com/ this site has been reccomended many times on this forum. I got the modified one with switch which reads more than the one without switch. I have the usb wired version to plug into laptop. works well 1 Quote Link to comment Share on other sites More sharing options...

It looks as if the one I ordered is the same as you recommend , it has a switch and USB cable. @£16.95. I'm not into fancy phones or bluetooth so the laptop one does me .

octuford Posted October 31, 2017 Author Share Posted October 31, 2017 Update After a sit down on the road today (Engine Malfunction) finally got a code to investigate with my new code reader. Got the code reader out and read the codes , came up as P0698-60 (don't know what the -60 means). which points to EGR, MAF or fuel rail sensors. Read that disconnecting the EGR multiplug will bring miracles , Hallelujah it worked , started first turn and has not faltered since, seems to be going better altogether. Now does that mean a new EGR unit or is it worthwhile trying to clean the EGR and rebuild. ?. Prices vary from about £100 to £250 depending on the model. It seems to be an electronically controlled with no vacuum pipes attached, anyone had trouble with these type before ?. If so how easy or hard to change ? Suggestions welcome Quote Link to comment Share on other sites More sharing options...
octuford Posted November 4, 2017 Author Share Posted November 4, 2017 Final update just to let you all know if your interested Got a new EGR valve assembly. preferred this to blanking it off. Fitted it quite easy really if you don't drop the bolts and metal washer down the back of the engine . Take off the plastic valance under the windscreen ( if you don't then take off the fuel filter assembly which means the system needs bleeding. ) 1/2 hour or so to do the whole job. Did not need coding/programming to the ECU/PCM Took the old EGR to bits and the electrical gubbins under the lid (with a silicon seal) on the motor had all corroded and rotted away . Surprised it had worked at all . I wonder how the inside got wet with moisture , considering its tucked away behind the engine out of the way off any road spray etc, Happy days are here again ! 1 Quote Link to comment Share on other sites More sharing options...
FatHead1979 Posted November 6, 2017 Share Posted November 6, 2017 At least your EGR was easy to swap out, on my 1.8 TDCI it's integrated into the manifold and is not a small job to remove. Glad it got it sorted out for you though. Quote Link to comment Share on other sites More sharing options...
octuford Posted November 6, 2017 Author Share Posted November 6, 2017 Thanks Damian , It was easier than I thought it would be , apart from holding the washer in place while trying to start the bolts in with one hand. Quote Link to comment Share on other sites More sharing options...
