broke down in spain, can someone tell me what this is

[Viva_65]

Ahh the picture is too big, on the bosch ve diesel pump, 2.5 di engine

What is the solenoid on the side of the pump with the cable?

At first i thoughy the fuel cut off but i was able to run it with it broken.

Os it the cold start solenoid? Does it affect the pump timing? And does anyone have a link so i can search for the part here. I cant find a replacement online at all

Thanks

You need to give more information on the year of your van and if it’s the original engine fitted very difficult without a photo m8

If the photo is too large (MB) try sending it to yourself in WhatsApp or Telegram. Open it in the app and save it to your gallery. This will force a compression of the photo that is easier to upload here. Size is usually in KB after compression.

Busy cleaning out my MK4, maybe this is the photo you need to identify your Pump. Note on the side of the pump a horizontal cable. I believe that’s the cold start device

Hello thankyou for the replys,

its. in a mk1 ford transit, its the 2.5 di engine but not sure of the year pump.number 0460 424 086

I.managed to cable tie it back but idle is rough understandably, until i can get a more perminant solution

I managed to get it to the festival, but every 15 minutes same symptoms of fuel starvation, when it does it i go straight to crack the injectors and there is air in everyone, im pretty sure my fuel filter is emptying and then drawing air, its a pain to bleed everytime using the fuel filter housing screw on top.

[Viva_65]

Yeah it looks the same as what peterr had posted, is it posible to find a replacement?

I read that most people disconect them electrically anyway but the fact that it holds the lever behind the idle screw means i need something there.

Could this cable snapping and me having the this arm in the wrong place lead to air getting in the pump all the time?

I have some days to work on it now,

Maybe your fuel lift pump is failing. Located on the bottom right on the engine block. Usually behind a small heat shield. (While facing the engine) below the exhaust manifold. A round disc like device with fuel lines in and out. Check that the bolts are still tight. Known to wiggle their way loose over time. Maybe someone here can suggest a way to test it (like maybe opening up the fuel filter inlet to see what if fuel comes out while cranking?)

You may be able to disconnect the cold start solenoid hex bolts to get inside and rig a recovered piece of cable, wire, bicycle cable etc. and clamp the extension together with the original cable.

You don’t need the cold start unless somewhere very cold if it’s only the tick over that’s the problem adjust it there’s a adjuster screw on the pump if you look at the throttle cable and the arm on the pump you will see it there are two adjuster screws one for idle and one for the max revs that should have a tamper proof seal on it unless someone in the past has wanted more speed out of the van .
Can’t remember if it 8 or 10 mil spanner size locknut you undo and adjust with a spanner or screwdriver screw in to increase tick over

Thanks guys, i put a new lift pump on in a different breakdown i had about 1000 miles ago but its true it was a cheap one i carried with me in emergency, but sure i didnt know they wiggle loose so i will check that, i still have the original as it was not the fault at the time. Ive done tge reverse bleed off mod on all the injectors so the return comes out of number 1 injector now.

Ive only adjusted the idle on the screw thats on the lever with now the snapped cable. I understand i dont need the cold start but does tgis need to be very accurately in the right place? I was going to source a new part for this reason but as i cant find it, more than likely i will tie it up with steel wire.

Yeah i was hoping this is why air could be coming into the pump but i think there unrelated.

Does anyone ever change the plastic pipes for rubber hose and barb connections? Think i would rather change the entire pipe then trying to find a pipe thats split then make a patch.

[Peterr]

If you mean the hard plastic pipes from the fuel filter to the pump. Not sure if that would be ok. Is there pressure in those pipes? Rubber may be too elastic and swell, unless they’re fiber reinforced and designed for pressure like air compressor hoses. Could it be the opposite, the sucking could cause it to collapse under vacuum effect? Not sure on that. I was wondering too because they’re hard find but eventually was able to recover used one from the junkyard.

[Viva_65]

Yeah thats the ones im thinking those pipes yeah, i would like to run a clear hose so i can see if any air comes in, think i will swap out the pipe for rubber, leave that one in place and try that, well first thos cold start lever

[Peterr]

Before doing that did you check the if lift pump is working? Open the fuel filter intake coupling coming from the fuel tank. Crank engine, see if fuel spills out the back of the fuel filter.

If you have air in the system it means you have a leak. Its much easier to look for leaking diesel than replace the whole pipe. Check for leaks and if no leaks then check lift pump as Peterr suggests. I have an electric lift pump on mine and it works fine, so you could consider replacing the mechanical one.

[dumper]

If air is getting into the system it’s going to be from the pipework from the tank to the lift pump the suction side I had a problem on my mk3 the pipe had rubbed through on a clip to the body the pipe coming out of the tank had a joint in plastic pipework that was factory I replaced it from there to the lift pump with Flexi fuel pipe
the di is a strange fuel system it’s the only vehicle I’ve known that can get air in the system from the leek off pipework you should be all right on this side with doing the pipe mod unless it’s sucking air on the plastic connection on the injectors

[Viva_65]

Okay, just had a moment to take these lines off, this is what goes into the fuel filter housing, i pulled 2 out and you can see they are very hard and torn. As dumper said tho actually anything after the lift pump sure would leak fuel rather than suck air?

Anyone dealt with these seals before? Or know there original shape.

Im hesitant to cut them off just yet
