Hi, I have a Kia Rio 2005, 55 reg (new shape) 1.4cc petrol. Every now and then the engine doesn't fire up, it cranks over fine but does not start. I have changed the spark plugs but fault still occurs every now and then. Ok for a few days then it doesn't fire up, after a few turns of the key it starts, then back to being ok for a few days again. I have also swopped key for spare, same fault. Please help??????<BR itxt="1">

could be the immobiliser unit not picking up the keys either via the antenna around the ignition barrel of the actual immo unit itself, a kia dealer should be able to plug in diagnostics and pick up a fault code if it is the immo system

I will second that.
Happened to my Rio diesel and it was the immo unit that was faulty.

Thanks.


I have noticed that when it won't start the immobiser light (car symbol with key in it) isn't lit, then when I try again the light is on and it starts. I have put a code reader on it and it has come up with p1693 Mil Circuit Malfunction. I have read that it could be as you said immobiliser problem but others have also suggested that it could be the Crank Shaft Position Sensor.



Cheers

would put my money on immo relay/unit, classic symptoms if immo light doesnt come on when cranking and not starting

I bought and fitted the immobilser pick up ring that goes around the ignition barrel (Antenna) and so far so good, starts everytime.


Thats for all the info chaps.
