Right, thanks Mark

Mark, tell me - I've just been researching, and the timing order is 1342?

Does that mean I connect the lead from no 1 on the dis pack at the timing belt end, and then a lead from no 2 on the dispack to the one at the back of the engine?

Could you explain in fools terms, where on the plugs my leads need to go depending on what number is on the dispack?

Cheers

I would have thought that 1 goes to plug 1 at the timing belt end, 2 goes to the next one behind it and so forth with 4 being at the baulkhead end.

Sorry mate couldnt resist  

Ummm Mark seems to be offline now.....LB's on he might be able to help....or i see MarkJay is on....he might be able to post a pic for you  

And im off now....hope you get it sorted mate  

[TheBoy]

I imagine 1 goes to front cylinder, 2 goes to next one back, then 3, then 4 at back...

Ok, had a skinfull last night because I was pss'd off with this, but looking at it with a (semi!) fresh head this morning, I'm going down to the project car to look at it logically as to why it won't start.  

I've written down a list that may help me:

Symptoms
_________

Won't start after rebuild
Backfires like a beast - through the inlet
Possibly no spark (but hard to believe based on the above)

What we know
____________

12 volts at DIS pack
Fault code 19 exists, (even though it's never been fired up)
There is definately fuel at the injector rail
The engine earth is good.

What I'm checking today
____________________

1) Order of HT leads
2) Cam sprokets are in the correct keyways, and valve timing is correct
3) Try spare crank sensor
4) Check body earth
5) Try the spare ECU?
7) Double check there is a spark using a timing gun and seeing if it flashes
Check all sensors are plugged in and all connectors are in the right place and fully home.

If this doesn't work?

Tow to remote location, pour petrol inside, throw match and leg it!

No - seriously, if anyone's got any logical additions to the above that may help in getting this sorted, I'd be really grateful to hear them.

Cheers!

Do you still have original crank sensor from your original engine to try, my thinking:

19 is a cranksensor 'incorrect signal' so ECU is getting signal, but is ruling out as invalid/not usable.  Could be all the work you've done has stressed its cable, hence it perhaps giving intermittent signal, thus intermittent firing.  Not sure why seems to be firing in inlet though.

[JamesV6CDX]

Yup, I've still got a spare, and it's on my list of things to try.

I would imagne that, there is only one thing that would cause an inlet backfire, and that would be if a cylinder is trying to spark when it's inlet valve is open!

This could be only two things really - plugs firing at the wrong times (HT lead mixup) - OR valve timing not right, eg, if both cam sprockets were set in the inlet keyway etc, all the valves would be going up and down at the same time!

I'll post up my findings later

[Marks DTM Calib]

Cylinders are numbered 1 through 4 starting at the cam belt end through to the flywheel and.

The leads must connect the corresponding cylinder to the coil on the DIS pack.

If the cam sprockets were wrong then you would get some VERY interesting effects!

Still sound like in-correct spark lead fitting.

[JamesV6CDX]

Well, checked the leads, and they seemed to be corresponding to the right plugs according to my spare DIS pack. However, just to be sure I removed the DIS from the car, took off all the leads, and started from scratch refitting them.

Turned the key.... VROOM!!

It runs. But I'm sure the leads were right first time. But they can't have been!

Grrrr

Thanks mark, I owe you one.

Glad you got it sorted  

[Timbuk]

If that was a V6 it would have gone VROOM VROOM Glad you got it sorted though

[JamesV6CDX]

well now, I need to fit the other header tank (backfire split the existing one), and clean out the big breather tube, and fir the exhaust properly, because it's not connected from the cat back yet

It goes though, I'm a lot happier!

With it running, I also tested that I'd engaged the engine and box properly, and it selects gears, moves backwards and forwards, so all must be well on that scale!

As long as it doesn't rain tomorrow, then it should be project 1 sucesfully completed!!

[STMO123]

Well done James, you got there in the end

[Marks DTM Calib]

Good news.

So was I close to getting the cause right  

[Taxi_Driver]

Was i close too
