Hi,

   spent the weekend changing the cam-cover gaskets and plugs, leads etc (inbetween running away from the rain and generally freezing my tits off). First problem encountered was that the stealers didn't give me the right parts, or rather, insufficient parts. Paid for and received a receipt for 2 x camcover gaskets. What I actually received were two gaskets, in 1 pack....so basically one side or one gasket kit.....very helpful. Anyway, didn't discover this until I'd stripped one side down. So fitted the new gaskets to that side, along with plugs and leads. Cleaned up the other side as best I could and applied some new sealant and fitted new plugs and leads. Put everything back together and........nothing Engine turns over but doesn't fire. So......obviously I'm going to have to pull everything apart again and see where I have gone wrong but I thought that I'd ask here first to see if there are some classic mistakes that I may have made. It's possible that not all the leads are on in the right order. I will have to search out the firing/DIS arrangement on here. However, surely the engine should still fire, albeit it badly? So I'm thinking that there is no power going to the DIS and there no spark at all. Is there a power lead to the DIS that I could have removed by mistake? It was hard seeing what I was doing, even with the scuttle removed, so had to feel my way around the DIS. I guess that it's not too hard to check for a spark. If not the DIS/spark, then I was thinking fuel. Is there a lead/plug for the injetctor loom that I may have unwittingly removed? The tank was pretty empty so I put some more petrol in. Does it take a while for fuel pressure to build up? I spent quite a while turning the engine over but to no avail.

    I tried to clean as much oil off the spark plugs as possible before removing them although some oil would have fallen in. Could this cause a failure to fire on all cylinders? I'll have to wait until next weekend before I can look at the car again so was hoping to pick peoples brains on here first. One thing I did notice that I thought might be wrong, was that next to the fuel pressue release valve (under the black plastic cap) is a small pipe pointing straight up. Could see anything to connect this to when I was put everything back together. Ideas anyone??? :-?

First easy chek is to read the fault codes.

and yes, the leads connect up slightly strangely on the Passenger side 2-4-6 bank

[TECHNOPUG]

Is this the firing sequence?

Looking from front of car towards engine

DIS PACK
1-3-5
2-4-6

ENGINE
5-6
3-4
1-2

[Marks DTM Calib]

Right....leads are wrong on the DIS pack for the 2-4-6 cylinders

They need to be as per:



If you remove the scuttle cover or move the cable tray over then you can just squeeze your hand in and swap them over.

You have three wrong so I am not surprised it wont run  

[TECHNOPUG]

Can't see your picture at work - will have to wait until I got home. I actually paid more attention to the 2-4-6 bank than I did 1-3-5!

Hmmm....I'm trying to think back now. One of the leads was very short, cylinder 6 I think. That was the plug that had totally deteoriated. I think that I actually plugged that into 4 on the DIS pack. And cylinder 4 to 6. It's all guess work until I go and have another look on Saturday. It did get a little confusing as although the new leads were numbers, the left back had long, medium and short leads; the right had were the same (so two of each) but of course the original leads are all individual lengths.

[Marks DTM Calib]

It should be:

1-3-5
4-6-2

Just moved the pic to the images server.

[Marks DTM Calib]

Just to note, the later DIS pack has the connector on the right end by the 4 and 1 connetors

[TECHNOPUG]

So the firing sequence SHOULD be:

Looking from front of car towards engine

DIS PACK
2-6-4
5-3-1

ENGINE
5-6
3-4
1-2
?

That can't be right as the 2-4-6 bank all came off the front row of the DIS.
So your image of the DIS is looking from the back of the engine, forwards, towards the bumper?

In which case:
Looking from front of car towards engine

DIS PACK
1-3-5
4-6-2


ENGINE
5-6
3-4
1-2

?

[Marks DTM Calib]

The latter is correct  

[Marks DTM Calib]

And here is the reason why its like that.

We have a firing order of 1-2-3-4-5-6

So, here is the table of what cylinder is on the exhaust stroke when its partner one is on the firing stroke

1 - 4
2 - 5
3 - 6
4 - 1
5 - 2
6 - 3

So...to pair the coils we have

1 - 3 - 5
|    |    |
4 - 6 - 2

[TECHNOPUG]

OK - I think that I have 2 & 4 the wrong way round. Would this be sufficient for the engine to fail to fire on ALL cylinders?
I guess it must be!

[Marks DTM Calib]

OK - I think that I have 2 & 4 the wrong way round. Would this be sufficient for the engine to fail to fire on ALL cylinders?
I guess it must be!

Quite possibly as it will also affect the ignition voltage on the opposing cylinders which are connected correctly

[TECHNOPUG]

OK - that all makes sense and will be an easy correction to make.
What about "One thing I did notice that I thought might be wrong, was that next to the fuel pressue release valve (under the black plastic cap) is a small pipe pointing straight up. Could see anything to connect this to when I was put everything back together. Ideas anyone???" I didn't have any parts left over and I could see any pipes at the back that weren't connected to anything  :-?

[Marks DTM Calib]

A small silver coloured pipe about 4mm or so in diameter and about 20mm long.....off the cylinderical body of the fuel pressure reg?

If so, it has the thin pipe connected to it that comes of the main pipe that connects to the feed for the idle valve.

[TECHNOPUG]

Oh OK. Where would I find the idle valve? Or should I just hunt for pipe that isn't connected? What will happen if I try to run the engine without this connected?
