If you do have the Butterfly Flap mechanism in front of your Intake Manifold I would suggest you remove the flap to see if that makes a difference. Most Lost CRD owners have done this!
The plastic gears get a crack in them so sometimes it jams and sometimes it moves....maybe jams when its hot or maybe it jams when cold
OK back again,
I have had the tank competely off this time, cleaned it all out (not much crap in it at all, beauty of plastic tanks) I have also had the turbo off and, as suspected, it is not a variable vane. All seemed ok with it though, no loose bearings and no whistling or smoke to indicate an issue. Cleaned all the soot etc out of the egr all sparkly new looking. I have no issues with this side of the motor now in my eyes any way ha ha ha ha ha. You guys may still have.
I will most definately be re fitting the fuel lines to the tank with sweated pipe and clips to make sure a tight seal, although, I did use some clear hose to check for air on the tank to filter pipe. I also noted, that through the period when switched off, the fuel was draining back to the tank. Although she is now back to starting first thing, and I have refitted the non return valve, there is obviously air getting in somewhere to allow back drain.
That to me though, doesnt make sense that it starts no prob first thing, then, after a run, wont go for anyone, but fires straight up on easy start (I HATE THAT STUFF!) and runs like a dream from there on in until you stop, and back to square 1.
I have also put clear fuel pipe from the filter to the pump intake, again, I can see no air at all, even after the drain back on the tank to filter line from the filter. To try and cure this, I bypassed the filter had a non return valve connecting the pipes, it still had drain back so suspect even more the connectors at the tank end are ****'d. Just seems daft there is no air though.
I am begining to wonder whether a gallon of petrol and a match may do the trick!! Silly as it sounds, it had its anual test and passed the emmision check with flying colours, so I cannot see it being the injectors.
I also note, there are no other wires at the tank end, other than those for the sender unit. If I get the 'in tank' pump, is this just the one connection for both?
As a bit of a side laugh, I have just recieved my new hearing aids, and I heard for the very first time, hissing from around the pump. To my detriment and unprofesionalism, I did not replace the copper washers on the banjo's. (What a pillock I am) however, the hiss has now gone having done the deed, but the issue still remains.
Also, a really stupid question, where the hell is the throttle body with the butterfly valve in it? (If thats what it is?)
This has to be the worlds most crazy thing on a car. I have NEVER had an issue like this, working on evry diesel you can imagine from huge trucks to bloody ships when I was in the Navy. Talk about wrecking ones head ........................................
All the best guys
