So I've not resolved the issue but thought I would make a note here just in case anyone else comes across this thread.
Spoken to Citroen main parts team today (had to ring service and get them to go find the parts team as they _never_ answer the bloody phone) and;
The 2.0L Diesel engine (XURHKH) only has the one pump and it's the on on the engine. No "lift" pump. The fuel tank only has a sender unit in with the fuel level float switch thingy.
The manual priming bulb (that I suspect is part of the issue) is part of an assembly that comes with other bits and bobs. Part number is 1574 CN, retail inc vat circa £210. But... it's not in stock anywhere and has no lead time against it so the parts guy said that means it's no longer available.
I think I found the right thing on German ebay for 120 euro but not convinced that buying that is a great idea.
Still getting the occasional engine warning light error related to glow plugs and whilst I don't think that failing glow plugs would cause these issues I figure I should probably just do that to rule it out.
Still struggling with this.
Not sure if anyone has a 2.0L and can confirm if there is an electric lift pump and where it is. I'm struggling to find a part number from anywhere and all the online retailers only seem to have the sender, no pump.
I have now managed to get all the bolts loose on the fuel tank but haven't found time to drop it and physically check.
On a suggestion from somewhere else I have also just tried changing the manual fuel bulb pump but frustratingly the one from Autodoc that says it's compatible is not. Either the connectors or the one way valve are the wrong way around! Still, I've blown some nice bubbles through the fuel line now.... ffs.
Just had a very similar issue with mine.
Rear drivers indicator has been intermittently giving me problems for a while and at the last MOT I spotted the earth was corroded. When I looked at it last week there was very little of the earth left in the connector. I went with soldering a flying lead to the track and then fixing it under the bolt that holds the cluster in place. I probably ought to go have a look at the passenger side as well as I assume it will be doing the same thing (but it's not giving me any problems currently.
I like the idea of drilling a rivet out though as I'm a teeny bit concerned that the solder might not hold.
Anyone with any comments on this tool? Seems to be getting a bit of love elsewhere on the interwebz;
Seems you may be a man after my own heart @RegW.
I like the idea of having a OBDII cable plugged into an ESP32 or something similar (low power for obvious reasons) that is just sitting there logging / monitoring things generally. I plan to fit a second battery and a DC -> DC charger so thought I might monitor state of charge on that for example.
In your testing have you found any free (FOSS?) software that does a reasonable job when using a OBD to USB cable or one of the OBD to Bluetooth dongles? I think I have a couple of those kicking around somewhere but never found any decent software so they were always useless to me.
Hey Team Dispatch / Expert / Scudo,
As mentioned in a previous post, I'm no stranger to tinkering with vehicles but my "golden age" was well before ECU's were a thing and I keep finding that I'm stuck wanting / needing to see what the ecu thinks is going on.
I'm sure this is a wide question and probably starts with "how much do you want to spend" but I wondered if anyone could give me some pointers on what code reader would be a good option, either in general or for my Dispatch.
I have a cheap and nasty no name one that I acquired from a friend but wondering about other options.
Thanks for the replies.
I'm also not so sure I trust the AI (I work in IT so I get to see behind the curtain sometimes). I(*) have finally managed to move one of the stuck bolts by leavening the cage out of the way and getting a 24mm thin short spanner in there. (* I say I... My mate Martin who shares an office with me and is better at spannering than I am....) Just one to go now when I have another hour spare.
@OAT, I had never thought about contacting the main dealer. Great plan. I did do a few ebay searches but I'm never totally convinced that I trust them. Understand your logic, they won't want to be faffing with returns but still a teeny bit dubious. I'll have a look though.
@RegW, apologies, that would have been a really useful bit of info to include. It's the 2L Diesel, Engine number (if that helps any) is DYXA4043494. The variant (according the the log book) is XURHKH. I had assumed that I had one but the Haynes manual combined with the (apparent) lack of wires made me question my logic!
+1 for cup holders.
I like to do a little bit of 3d work but am no where near good enough to create one of the in dash pop out type things (which my Dispatch doesn't have).
I started working on a blank for the holes in the back door pillar but dropped the last one into the pillar never to be seen again!
Hey All,
I'm new here so be gentle!
TLDR;
How do I check if I have a lift pump without dropping the tank?
Longer Version;
My knowledge of engines is fairly rusty and mostly based around older vehicles with no ECU (2/2A landrovers, "proper" mini's, that sort of thing) and also very limited on Diesel engines. When I was young broke and stupid I did plenty of work on my own cars but gave it up when I could afford to pay someone. For various reasons I am now old(er) and again finding myself broke (as a result of still being stupid) so working on my own vehicle again.
In March ish I acquired a 60 plate Citroen Dispatch and it transpires that it has what appears to be a semi common fuel related intermittent none starting issue. It cranks just fine but won't fire, cracking the bonnet finds the manual priming bulb not quite as solid as I would like, a quick couple of squeezes and then it runs. Sometimes disconnecting the air intake and a liberal amount of easy start is required.
I established that most (? all ?) diesel engines have a Low pressure (lift) fuel pump and a high pressure one. So I disconnected the fuel line on the output side of the filter and turned the ignition on. I fully expected to get covered in fuel but nothing appeared to happen. I tried again on the input side, same thing. I also noticed a distinct lack of "pump noise" that I think I'm expecting when the ignition turns on that would indicate the lift pump pressurising the LP side of the system.
So, my conclusion was that I should find and test the pump by directly dropping 12v across it. To do that I need to drop the fuel tank....
Today I tried, and failed to do that (Captive bolts on passenger side spinning and I can't jam them) but I think I found some info that doesn't make a lot of sense. The Haynes manual has a bit that reads "On some models only a fuel level sender unit is fitted - no lift pump" and whilst I was under the vehicle swearing and bashing things with various hammers I noticed only 2 wires going to the top of the tank.
So this got me thinking... Two wires to me sounds like the fuel level sender and the bit from the Haynes manual makes me think there might not be a lift pump...
Can anyone provide any guidance on either how to check if I have a lift pump without dropping the tank or how to drop the tank if those two bolts won't come free or if I'm going about this totally the wrong way and need a diagnostics 101 course before I go dropping bits of the van off to test.
