BP2411 Posted June 3, 2020 Share Posted June 3, 2020 Please tell me it's a cheap fix 馃槀 My 2009 1.4 tdci fiesta isn't playing nice lately, get this code on forscan, usually I clear it and it goes away for a while but at the moment forscan doesn't want to connect for some reason.聽 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted June 3, 2020 Share Posted June 3, 2020 It's either a duff injector or damaged injector loom...neither are cheap fixes lol.聽 Though you could make sure the plug isn't loose for free... Quote Link to comment Share on other sites More sharing options...
BP2411 Posted June 3, 2020 Author Share Posted June 3, 2020 As soon as I seen injector I knew it was wishful thinking it was a cheap fix. I'll take the air filter off when it dries up and have a look, is it worth unplugging all injector electrical connections and spraying them with electrical contact cleaner?

I wouldn't unplug all of them, you might end up with more faults than you started with! 聽 I assume it is always cylinder 2 injector that shows the fault?聽 If so, you could unplug that one and give it a spray with contact cleaner.

BP2411 Posted June 3, 2020 Author Share Posted June 3, 2020 Yes, always cylinder 2, stupid question, which injector is number 2? Do they run from the battery 1,2,3,4 or reverse?聽 Quote Link to comment Share on other sites More sharing options...

BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 Took it apart yesterday, sprayed electrical contact cleaner on it & left it, will put it back together today and see what happens.聽 Quote Link to comment Share on other sites More sharing options...
BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 Put it all back together and it worked for about 5 minutes, forscan still won't connect either but a cheap eBay bluetooth adapter connects.聽 Quote Link to comment Share on other sites More sharing options...

BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 I don't, I get the power light on my WiFi adapter but no connection, wired connection to a laptop also won't connect, cheap eBay one connects and gives code聽P0643.聽 Quote Link to comment Share on other sites More sharing options...

nicam49 Posted June 6, 2020 Share Posted June 6, 2020 To聽 be absolutely certain, I'd disconnect in turn each injector then without switching engine on (turning ignition on) I'd see what error code each disconnected injector produces. Sometimes injectors are numbered by firing order, so just to make doubly certain you're on the right track... 聽 聽 )聽 Quote Link to comment Share on other sites More sharing options...
BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 Laptop & phone, just pulled the fuse, put a new one in (I know it wouldn't get power if the fuse was no good) and it worked, maybe pulling the fuse caused it to reset, anyway that brought up 6 codes 馃槀 which made me believe it was the multiplug in the engine bay, unplugged it, reseated it and it worked, put the air filter back on and the car started running bad again. I don't know if it's just my car but this Ford loom lock is ridiculous, it sits in perfectly but if you put slight pressure on it, it comes out of place and throws up codes. Is it possible to add an after market air filter to this engine as it's a PITA to remove the air filter & every time I put it back on it knocks the plug again.聽 1 Quote Link to comment Share on other sites More sharing options...

The loom doesn't sound very 'locked' if it falls apart that easily lol?聽 Surely it'll only take a pothole or speedbump to knock it on the road.聽 You could whack a cone filter on it if you wanted but I'd focus on making the plug more secure personally.

BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 My plan is to chuck a cone filter on then secure the plug, it doesn't fall off, just has slight play in it which I assume is stopping all pins from connecting,cause the engine can be running fine but if I touch the plug it then sounds like a tractor.聽 Quote Link to comment Share on other sites More sharing options...
BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 The lock is on the other side of this loom, it connects to the injectors, glow plugs & something else MAF sensor or Cam sensor maybe?聽 Quote Link to comment Share on other sites More sharing options...
Danny2626 Posted June 6, 2020 Share Posted June 6, 2020 I had this problem on injector 4 I removed all plugs from injectors contact spray on all of them I鈥檓 sure it was loose any way small bump could of caused a bad circuit! Went into limp mode/very juddery. But after a good spray and making sure they was well connected again touch wood no problem for a month so far hope you sort it mate聽聽 Quote Link to comment Share on other sites More sharing options...

BP2411 Posted June 6, 2020 Author Share Posted June 6, 2020 It has a locking collar on but it doesn't actually lock, it feels like it's locked but can be moved, I did cable tie it but when I put the air filter back on it knocked the ties and it started showing eml again.聽 Quote Link to comment Share on other sites More sharing options...
