The ecu must be powered up before you can communicate with it.

ok got it powered up last night.
checked the comms lead

wire side of plug

top of dta 15 pin plug 1-2-3-4-5 have continuity to top 5 pins on the computer nine pin end (blue,green,yellow,red,white)
2nd row of pins 1 (sheild (button) has soldered link to both pins 2 +3, terminal 3 white wire linked to
3rd row pin 5 , 3rd pin is light blue goes to button

got port error

checked serial connector was com 6 -changed to com 1 (which it said was busy) but it let me change it anyway.

Now it try's to connect to dta win but fails and says can't connect ecu not connected or switch off.
Had a quick look at ecu and no obvious damage to any components.

thanks for any help
