Partner 1.9D hesitant then stalled!

Re-sent!

Got that a treat Roger..

It sounds like a little machine gun The solenoid is repeatedly operating and then dropping out.

Now that's definitely wrong. I would hazard there's a high resistance in the supply to the electronic module on the pump. Check the connector that goes to it on the end of the pump as a first thing...

A high resistance will initially allow the solenoid to operate and then the voltage will fall and cause it to drop. The voltage will then recover allowing the solenoid to operate again and then it drops. Hence the fast clicking...

It's electrical and I reckon external to the pump..

The bad connection could be anywhere from the fuse box to the pump..

[Rhothgar]

I might be a dimwit, Jim.

I've just realised that when I recorded the sound it was after I had stripped all the pipes off and had only lightly reconnected the block connector!!

I will go down to my Mum's at some point today and re-do as I am pretty sure that the solenoid gives one loud click.

If it does click surely that rules out the solenoid anyway, does it not?

Any piccies you have of a Delphi pump side armour would be good if you have any.

Yes, it does Roger...

If you are only getting dribbles from the delivery ports then sadly one has to suspect heavy distributor head wear from running on veg or an internal blockage due to the stuff..

Do check you have a very adequate supply of fuel to the pump before going too deeply in. Basically fuel must be flowing in the return pipe at all times to ensure adequate transfer pressure inside the pump to allow the high-pressure parts to function.

I have an armoured Lucas pump here but it may be a while before I can get to it to photo it unfortunately. The problem it that it's de-armoured at present and I'd have to re-armour it... Time is very much at a premium at this time

Where can I find the return pipe, Jim? Doe sit come off the pump somewhere? And also, do you know where the tank filter is located on a Peugeot Partner Combi?

I wouldn't waste your time with it then. If the fueling is OK, then the pump's coming off anyway and I'll find out soon enough.

Someone has a spare pump on Ebay. Do you know how the pump coding works? The last four digits are different between that and my brother's pump.

[CitroJim]

The return pipe is on top of the pump Roger. It has a small tee in it where the leakage returns from the injectors attach.

Nope, no idea at all I'm afraid on the tank filter location but I'd guess it was in the tank. Look for a Xantia-like big rubber bung above the tank maybe or follow the pipes back...

I have no idea if the immobiliser can be recoded to the vehicle using a PP2000 Roger or if you would need the pump module and transponder.

If you end up replacing the pump, de-armour both and transfer the immobiliser electronics over. You'll find the stop solenoid is hard-wired to the immobiliser module.

Sorry for a less than helpful reply Roger

[Rhothgar]

Naw! That's very helpful Jim. (Apart from stating the obvious in Para 2)

Cheers, Mate.

My brother, being the numpty that he is (putting veg oil in when I told him not to), has now got a so-called mechanic bloke at the end of the road involved.

I've just had a word with the bloke and he is going to plug it into a Snap-On scanner because he reckons the crank sensor can stop the fuel being delivered to the pump - ON A NON-HDi ENGINE!

Correct me if I am wrong but there is absolutely NO way that this could cause a non-HDi engine to not start?

I can't see it Roger. A duff timing signal from the crank sensor might make it run like a bag of spanners but it would not prevent it from fundamentally running...

[Rhothgar]

Glad you concur, old bean!

The bloke did say hacwsaw the armour off though.

I thought it was impossible but if you hacksaw below where the rear plate on the pump cranks to the right and upwards to what looks like a lifting eye then it does look as though it can be done.

The armour seems to go over the rear plate and be separate from the armour entirely. If I undo the banjo bolt feed to the pump then, once hacksawed, I should be able to lift the armour off.

I am sure you probably have experience of playing with this armour, Jim. Will a hacksaw do it?
