    hi guys i have a 99 vs ute with 200000ks on it and it was going really well till the fuel pump packed it in. and now its not making spark well it will make spark but soon as you pull out the drive way it dies again. i have replaced CAS coils plugs leads so far still no change. i have run a test light over the dfi plug and its not getting power to there i also was playing with the key a few weeks ago and was thinking that that may have done some thing.
    any advice would be really help full...

    you said that the fuel pump packed in, did you replace it yourself? maybe the return line into the swirl pot is not connected causing it to die, however this would only happen if it had little petrol in the tank

    check the pins in the plug and dfi, sometimes do go in properly causing intermitantness

    Id first be trying to check to see if any error codes have set.Heres a link to a page that shows you how to do this test.Does the check engine light on the dash come on at all when the ignition key is turned to the on position or when the engine is started?It should come on,then once the engine is started,it should go off.This is basically a test to show the dash warning lights are all working and that theres not any blown bulbs etc in any of the dash warning lights,so if the check engine light doesnt come on at all,the bulb is probably blown,they are fairly easy to replace.
