HELP NEEDED WITH COLD START

hi all  (mk1 gti 83 )
im not very mechaniclly minded (still learning)
im having problems starting the car on cold mornings
i presume it will be the cold start valve

or better still if there is anyone in the york /selby area that could have a look at it for me
i would be very gratefull

not even sure if the right wires are going to the tts and aav and the wur
cant find a good engine pic anywhere on the site which shows the wire colours ?? :(

multimeter or test light across the pins for aav and wur. these get power when the fuel pump is running, easiest way to check is when engine is running. 5th inj only has power acroos when car is cranked over on starter cold.  check the black wire is on the 2nd spade on starter motor ok, if its had wrong motor or fallen off would cause problems

theres your problem! k-jet starters should have 2 spade terminals, 1 red/black wire plus 1 black wire.  the black wire runs to the 5th injector, without that cold starts will be tricky.  have another look near starter, see if you can spot the black wire hanging somewhere. if you have nowhere on starter to fit it, you need to buy a new starter motor!
