work this one out!! :@ speedo not working...

Hey guys, a weird one here. Speedo stopped working altogether yesterday without warning which has now confused the scorp majorly - it knows the cars moving but cant add miles to trip or odo so cant work out fuel economy reckons half a tank will last me 6 miles at the moment!!
So no speedo, tacho is jumpy intermittently, and the biggest problem of the lot which started at the same time is that I only have first 3 gears, wont whatever i do knock up to 4th which means its full on drinking the gas at speed cos its nearly always redlining in 3rd!!!
Im curious if this has something to do with the speedo being out?
shes a 2.9 12v auto
Has anyone else had this problem!? I hope so!!!! 
As usual any help is much appreciated
All the best guys
Chris

hi there
sounds like the vss is broken. it's a small box on the side of the gearbox. you won't get top gear without it working.
hth
btw, check all wiring to it, just in case.

I'd blame the VSS, except for the fact that he suggested the tacho was jumpy too. What does that mean? Jumping about wildly, or just moving normally in responce to unusual engine speed changes?
If wildly it sounds like an electical supply problem to the dash panel.

4th gear on the 12v is vacum controlled .... So check the small black vacum pipe which runs from under the IACV at the air intake . the speedo sounds like the VSS has gone as you have already been advised .

If the two problems are connected, the only common place is the supply to the dash, or the dash display itself. The speedo and tach respond quickly, but the temperature guage and fuel guages are heavily damped. Are you noticing any strange variations on these last two?

My speedo packed in yesterday, linked to a reoccurence of the ampage drain and last night coming out of a meeting to find my rear lights on but the switch off. It is with an autoelectrician this morning and I will report back (gulp)

That narrows things down a bit. Looks like a type 11.
Does anybody now the actual difference between the type 19 12valve petrol and the type 11 24valve petrol?
And what difference would that make?

Maybe when using the diagnostic mode (pushing the trip reset) the 24v displays different info?
The 24v engine redline on the rev counter may be higher?

Impossible to say. Only the tech who designed it would know for sure. It might be as simple as different software, or just a link to be changed on the PCB.
There were possibly six Scorps at Babbingtons Leeds and one in the scrap yard on the left (2nd one) a little way past the Middleton Arms (Thorpe Lane I thinks its called).
Latter Scorp was I seem to remember a 2.9 12v, though I don't remember whether the instruments were still there or not, it was three months ago.
If you fancy a ride over I'll join you. Email is harry.m1bytNOSPAM@tiscali.co.uk -remove the NOSPAM bit.

Thanks Harry,
I will get back to you, the electrician is going to reconnect the instrument console in the morning and now he knows about the type button he is going to confirm what the existing console is.
