Russ's 2.1 SED Auto now in Mandarin

[captainhaddock]

Very good Russ! cx IS just about falling apart Got some nice welding jobs to look forward to now as well. Not to mention those bloody rodents eating away on it
I wish I would know a way to keep them from my garage, tried just about everything...

But......I'll get that CX going again, and started straight away! Don't worry! Just got a bit distracted with XM's lately:)

And no idle speed issues

Seriously, I don't know how to tackle that on a diesel yet, mine is idling perfectly . Let me know!

[russ92xmsed]

You need a carcoon Jaap. A large inflatable mini garage that cacoons the car. Stop the mice from chewing France's finest!

I'll let you know how I get on with the idle speed. Although I doubt it will be the most interesting thing in the world.
You'll be able to do it know sweat.

Happy welding!

What is it with rodents and the CX? Actually cars in general. They love 'em

I'm looking after the neighbours pets this weekend. They have now added two rats to the family and I really don't like them at all. Do they ever smell Perhaps it's me but they smell absolutely vile and I hate to think of what a car smells like after they've been chewing away on it...

Hope yours smells OK Jaap and looking forward to seeing some CX progress reports

To keep mice and rats away get a young Tom cat.

Our neighbours got a kitten and it has turned out to be an incredibly good mouse and other animal killer. Unfortunately, it scared our nesting ducks off too.

Well something is up. And it ain't the battery.


Connected it back up, fingers crossed and cranked it over. Nothing, wouldn't catch. Cranked again spluttered into life just. Revved it up to get it going. Which it did fine and smoothly. Then allow it to idle, revs drop and no matter how much you press the throttle, it dies.
It runs rough ..lumpy when it drops below 500 rpm...which it will do won't it! loads of fuel in it.

When it does konk out, you can hear this gulping bubble sound from the fuel tank. Bit like a demijohn....So could I be right in thinking it has air in the system. Trouble is if it has, where on earth is it getting in.

If it is a fuel issue, then I suppose it could be a number of things. Fuel pump. Clogged fuel filter...new one one order anyway....split fuel hose somewhere, although there is no fuel leak.

Or is it because the idle setting is now so out, it just stalls. At a loss as you can see! So now it is time to riffle through some threads.

Really getting to the point of sending it to a garage in disgrace and getting it serviced and mot'd and not allow it back till it is behaving.

Oh well, can enjoy some sunshine this afternoon now.

[captainhaddock]

No sun shine here, but starting diesel..Did you already do this adjustment on that pump Russ. If so, more than likely something went wrong there. As for the starting: I still think your battery is on its last legs. Charged up or not.
Send some sun shine and wait for the Diesel people to come online.

It does sound like very sever fuel starvation and air Russ, especially with the noises you can hear in the tank...

As you can hear bubbles in the tank, from air passing down the fuel return line, then the air ingress is on the supply side and suspicion must fall on the filter head and primer initially..

Basically, with a Bosch the pump body must be full of diesel and at a pressure at all times for the engine to start and run at all. In other words there must be a strong flow of diesel from the return pipe to ensure this is so and if this return is all air and bubbles then the level or pressure won't be adequate to allow the car to run, especially at idle.

Translucent pipes are the perfect way to see where the air problem is occurring..

Also, do check the leakoff pipes as they can cause a similar problem although usually they just make the engine hard to start as they allow, if perished, the fuel in the pump body to drain away back to the tank and then on the ext start it takes a lot of cranking to refill the pump.

A plugged filter normally does not affect starting or idling; it just causes fuel starvation when the engine is under power.

Knowing how much aggro they can be my money is on the filter head.

[russ92xmsed]

Jaap, I can do my best but don't expect much!! No I didn't do any adjustments as the car wouldn't run properly and it needs to be warmed up to do it. I also agree, the battery might be toast. I did read if it isn't giving enough juice it can effect the glow plugs. But once started and revving at 2000 rpm, it was running fine. Anything below, lumpy and it gives up.

Thanks very much Jim for your explanation. It certianly seems to be a fueling issue. I have been traughling through some other threads and I think this is certianly the best idea to start with the filter head. I have ordered a new filter anyway, so hopefully this week I can get it done. Is it a rubber gasket that fails or is it some thing else like the entire head?

This is a case in point of my labelling idea of all the car engine parts. Would love to colour code everything... A sea of black pipes do not help quick identification! I will check the leak of pipes too for sure.

It's punishing me for not driving it regulary!

[captainhaddock]

A wealth of info Jim - absolutely great. Where do the leakoff pipes live?. I really must get into this. Thankfully my diesel has started OK up until now.
Takes a bit longer when warm, I suppose this is normal. You don't need to preheat the engine when she's still warm, do you?

[russ92xmsed]

Not really no. Unless it is really hot I think the manual says you might need to use them. But really only from cold.

Mine can hesitate to start when hot, but it is briefly. Not like what is happening now!
