i ave 17's mate

The 125 or 127 determines the speedo accuracy, what size wheels/tyres do you have?

went out to double check me dad's wiring n guess what? he had only connected 1 of the 2 brown wires comin from the car to the dash!!! connected the other brown wire and everything perfect now! ;-)

so what deos having 127 instead of 125 mean?

double check you have wire from dash or transducer (Cant remember which) connected to ECU, this caused mega probs with my car cutting out.

it reads 127

i heard a story from one of my friends who had a tigra that would not start when he took his clocks out to put white dials in.

the 127 or 125 is changeable by flicking the small microswitch at the top, this cant be anything to do with the dash, agree with cobra that it must be to do with maybe you disturbed a wire when wiring it up, check the wiring to the pickup around the ignition key if this is fitted to your car.

I drove my car to the MOT with no speedo at all!! the dash was empty, gave the tester a bit of a shock LOL.

The wire to the ECU is for reading the speed, I doubt this would affect the starting/running, but its worth checking.
As you didn't have a transducer with it, I assume your using the Corsa sender? You wil have earth and live (black and brown) running from the sender to the ECU, and the red and blue goes from the sender to the red and blue on the back of the dash.
Out of interest, when its done its self test, does the display show 125 or 127 mph before settling at zero?

the is a wire that runs to ecu - this need to be linled up right or car runs like a dog

The blue/black wire is for the fuel gauge so it won't be that. I don't think it will be anything on the actual dash, like I said above, the car will still run with no dash in it. I'm wondering if perhaps he's disturbed something when cutting the loom possibly?

i had a prob when i had my digi dash in, the car would just cut out on its own, was one of the blue/black wires that controlled the idle of the car

but then the car wont start!

yes the dash does excatly that!

When you turn on the ignition, does the dash do a self test, ie. everything lights up and the speedo reads 288?

CORSA B it did turn over 4 2sec's then it's like something jus cut's it out!

what corsa (b or C) only guessing but if the its a c and they are anything like a mk4 golf, the dash will be at fault, coz you have to code in a new dash with the immobilser code and other mumbo jumbo when you replace them on a golf....

cobra148 the dash works perfect! the car just wont start!!!!!

sounds like immibilosor(sp) problem to me

may need to get alarm checked out

The car should still start and run with no dash at all, have you checked and double checked your wiring?
