Sometimes Mixing the 2 black ones (Knocka nd phase) will result in a similar problem to what you have now. Have these been off?
Mixing black and white will probably = no run as you will have no crank speed, but i presume stu saw crank speed?

ok I went and had a quick look today.
Didn't have the IAW monitor but had a pectel monitor
on power up got the proper messages
i.e. level 8, MSD803CL
water temp was -55 before we cranked the engine but I have a feeling pectel monitors do that until the engine is running? asking experts...
when cranking the injection was showing 19mS, and ignition was showing 0.00degrees
Must admit I didn't look for cps signal but i did look at the pectel monitor faults after cranking and the only one was 'battery voltage low'
I noted it at 9.9 V @ ecu during cranking
didn't get any 'crank position sensor error' or anything else
spark was still doing it's own thing, seemed to have some sparking on 1 but not 3
there was plenty of unburnt fuel coming out of exhaust
anyway, decided to risk my DIS(secs dis board) L8 on the car
now it's a stage 1 setup was working on easter saturday as ForeigneRS used it to break my engine
put roosies car to stage 1 parts, dark blues/2 bar
wouldn't start
spark was still erattic/ squeeling/ continuous/ missing/ erattic/ whatever
So I ran away
can't think of what else to try until my car comes back from germany
anyone?

Also, if this car has the firewall multiplugs, open them and close them 5 or 6 times. this may be enough to fix it.

Stu(Roosie) Havent you swapped the removable firewall on this car?

I would throw a crank and phase sensor on thsi car personally. And TRIPLE check the wiring to them. A good electrical test of both on L8 is to power up the ecu and then disconnect and reconect the sensors plug. If it at least has continiuity the pump will prime when you reconnect it. Ive usd that test to find dead ones in the past.

Is this still going on 
Not saying people on here are dumb or not knowledgeable but....
What you need is someone with the experience and the right equipment
to solve this obviously difficult problem.
Didnt someone like that offer this on this thread ?

The firewall plugs are a FAR bigger cause of non running if you have them? Just to teh left of teh battery.

On my L8 with an IAW monitor, before the engine is started, mine does the exact same thing - reads -55 deg c for both water and air temp. As soon as the engine is cranked, the right temps come up (and works fine)
I think it is just part of the way that the L8 initialises. I guess the P8 is just more up to date!

was out mapping my car with karl and then all of a sudden car dies on cranking the car over with all karls monitors on laptop/ ect karl said there is no ignition signal problem was the plug had come off the phase sensor as stu says it may be a place to look

JJ, I know you didn't , I missed a off the end of my post.
Roosie, did you use the heat sink paste when assembling the ingition amp's? Can't remember if you've already tried them on a different car also...

Stu,
Thanks for your confidence
Roosie,
Just replied to your PM.
FYI, if you havent sussed it by middle next week, I will be in the area
and can have a look for you. Unfortunately, I am quite busy till then.
I have a "proper" digital oscilloscope, a test ecu S8
which can find
faults weber ecu's dont detect and also a 32 channel real time data
logging signal analyser.
I reckon I could figure it out with that little lot pretty quickly
Thanks for your confidence

Roosie,
see you still have problems, but as i said by PM, AS everything possible
has been checked, amps, loom, ecu etc, as i said, and i notice stu(msd)
also thinks possible crank sensor or phase, as seems like the ecu is not
getting crank sensor signal for ecu to switch amp for spark.
do you have a spare crank sensor to try.

SHE RUNS!!!!!!!!!! 
it must be something in the fusebox as i pushed my whole hand on the fusebox and its started sparking!! like a bag of shit but still runs (the fuses were ok" ther emust be something wrong undernee what does fuse 24 do?? the one on its own??
the only prob is now when it start and you turn it off an try start it again it wont start unless u leave it 10 mins must be flooding itself or any other sugestions?? at least it starts!!
Thanks everyone thats try to help escpecially "the original" "Stu" "Ryan" "Simon" ect
hope i can get it all sweetly running for santa pod
