My ute (2004 TD42 w/after market immobiliser) is being a PITA.

When i turn on the key, i get all the lights I expect (if the immobiliser's doing it's magic i don't get the glow plugs etc) - but when i turn the key to start everything turns off. I'm pretty sure it's not a battery issue as i've got 13V at the battery.

I'm baffled as to what's going on....


Full disclosure - the ute *may* have gotten a little damp the last time it was playing out.... this probably opens up the possible issues to include starter motor related stuff - but would that just cause the dash lights to turn off ?
