Hi tony thanks for your reply mate I did a typo it is a DXA597 not 58 fat fingers lol… I think I’ve found the problem as the wiring harness to crank angle sensor runs under the alternator the red wire that runs to it has broke away… so I’m in the middle of getting it sorted had to undo the air cond pump from bracket to gain access… now I have to undo the sensor pull it out and sort the plug out… I didn't want to take it out but I can’t get the plug end off as there is no room to get your hands in …I will let you know how I go mate…
