The problem was with the cold start injector/pre-ignishion injector on the side of the air intake manufold it had a B+ wire (ok) and a earth B-(brown signal ) wich was not working going to the injector , what ive done is ive thaken a hella 4pin relay supplyed a starter wire on 86+ from the key start poshion and an earth on 85 and 30 the 87pin will be the supply back to injector to replace the brown wire BOOM it starts first time every time :)
