saxo vts immobiliser problem!! URGENT!

  1. #1
    Right, so ive just changed my starter motor on my vts as it wouldnt start sometimes and the starter motor made a crunching sound. so the new 1 is fitted and it turns over no problem but now the immobiliser(key) symbol on the dash has come on.

    it will turn over but it will not start, ive had an electrical engineer come and check the key is still programmed to the immobiliser which it is and is picking the key up fine.

    So it still will not start...

    guys any help would be muchly appreciated...
