JX Won't start

[jokeruk]

As you may remember, my pump started leaking and I had it replaced with a second hand unit. I had taken it to Gasure on Friday to get the pump timing sorted properly - no problem with that. It was way out (around 0.6 instead of the proper 0.9)

However, after running fine all the way from chester to home (around 25 miles ish), coming down the slip road I dipped the clutch and she stalled. Couldn't get her started again at all and had to get recovered home (thankfully only a couple of minutes but took the guy around 40 mins to get there).

Once we got back home he put the jump pack on (i'd drained the battery trying to start her) and boom - started straight away. Now I can't get her started again. I've check the fuel solenoid which I can hear clicking as I put it on and off with the ignition on.

I've also checked the fuel by loosening the feed pipe at the filter end to allow a small air pocket into the pipe, tightened, turned over and the bubble was gone (i'm assuming that it's pulling fuel through with no problem).

I've even tried putting the pump timing back to where it was (after marking the correct timing of course). All to no avail.

Any ideas?

Slight update - I got it running after loosening the injector pipes to check that fuel was getting through, and tightening them up (still on the incorrect/retarded timing).

I got to work in it but when the time came to come home it wasn't happening. I've now got the battery on charge ready to put it back in tomorrow and have another go.

Is it possible i've got another duff pump?

Got stranded again last night at work by the van not starting. I managed to get a lift home with the battery and put a full charge in it overnight, and took it back this morning to have another go.

I pulled the timing back again and got her started - I just can't understand why it wouldn't start when the timing is correct. So I'm now looking at possibilities. When the first pump was put on the mechanic bent the injector pipes to get it on (it wasn't quite the right pump), so I'm going to check whether the pipes are going to the correct injectors.

The only other things I can think of is a) is the pump 180 degrees out? But surely the getting the timing sorted would have highlighted this? or b) the pump is fubared.

Any thoughts? Has anyone got a pic of their injector pipes so I can check that they are all in the right place (although I would have thought i'd have felt it if cylinders were down).

Hi, easy things first...when was the fuel filter replaced,have you tried draining a bit of fuel plus any water from the fuel filter?.
Are you using the cold start lever,are you waiting for the glow plug light to go out before you use the starter?.

The fuel filter was going to be the next one to change - don't know when it was last done - although the injector pipes do leak when loosened off so i'm assuming the fuel feed is ok. It's the same with the cold start lever in or out. Glow plug lights have never gone off unless they timed out (I do know that they are all good as I replaced them all when the pump was changed.

dont assume, fuel problems are notorious, my little tipper would idle all day and go to 40-50 mph fine but did not like full boot and when laden it would stutter and create all sorts, changed the fuel filter (same as on our vans) and running sweet again,, fill the fresh filter with fuel prior to refitting as well

Hi, I've been experiencing very similar problems with my jx after fitting a new cambelt and rebuilding the head. When I bought the van it was very smokey, low on power and needed lots of starter to get going. Anyway the belt snapped and required the above repairs. I expected everything to be okay once it was all set up. I had great difficulty in getting the injection timing right, even with all the vw pins and locks in place it would always idle badly and smoke.
A friend of mine suggested that since my van was 25 years old the injection pump had probably been serviced or rebuilt at least once. He thought that the pump internals might have been refitted 180 degrees out, thus when I thought I had timed up properly my engine was 180 degrees out also. Once I swapped my timing pump pulley locking pin in place after rotating the pulley 180 degrees I could easily set the timing precisely with a depth gauge . My engine then started easily and is running very well now.

Hi all,

Next part of the saga! Fitted the new fuel pump yesterday (filling with fresh fuel). Eventually managed to get her started and she ran ok (apart from the timing/smoke etc.).

Came to start her this morning for work and she didn't want to play. Took a bit of cranking, and she fired up on what felt like 1 or 2 cylinders before dying again. Cranked again and killed the battery - no starting.

Next thing is to check the glow plugs again (and relay, although there is a marked voltage drop when the plugs are on). I don't think the pump is 180 degrees out as the timing I had done by Gasure should have picked that up.

Is it possible i've got (yet another) dodgy pump? I've got to admit, I'm starting to get a little frustrated with this now as it's been months with problems

Just for reference;
my start procedure,pull out the cold start ,turn on the ignition and wait for the glow plug light to go out, start the engine [normaly starts instantly and runs a bit rough for 30 seconds or so ] if it does not start with in a few cranks I go back to my start prodcedure.
I recon the timing is retarded* as you are getting a lot of smoke on start up.
*this will make it much harder to start!
How are you starting yours?

[jokeruk]

It's actually almost impossible to start from cold when advanced to the correct point! I have been having a look and noticed that there is some fluid (I think it may be diesel) on the block under the no3 injector - could a faulty injector cause this issue?

[dave friday]

leak.. perished/split leak off rubber tube/s.timing..odd should be easier to start when the timing's advanced,which way are you turning the pump to advance the timing?.
I've got a London phone number if you want to have a chat about it?

I've just taken another look and was wondering - the pipework doesn't seem to match the picture of a new set on brickwerks. Can someone compare this image (mine) with theirs and see if the pump ports on the back match to the correct injectors?

If they're wrong It would explain a lot!

That looks wrong to me although I haven't a jx. Also one of the pipes looks as though it has been bent at right angles instead of being a gentle curve. It looks as though several pipes have been bent out of shape.

Here's a view of my 1.9 (ignore red lines - that was for something else)

[jokeruk]

Yeah, they have been bent as the first pump that I had a mechanic put on wasn't quite right. It looks as though the injector pipes for 2 and 4 are the wrong way round.

I'm going to be changing the pipes anyway (will take a nosy at the for sale section when I get pain in a week or so!) but will try swapping the pipes over (yes I know it'll be hard an risk fracturing them, but if I do it can't be more off the road than now!).
