Question about Renault 181
Thanks for your response - I thought the same re: crank sensor & found no ac voltage under cranking so replaced it. Still no noid or sparks. Don't recall seeing a 'Check engine' light at all so sounds like your suggestion of ECU doing nowt is likely. I have plenty of battery voltage inputs to ECU but seemingly nothing coming out. Do you know if ECU's are interchangeable on this model? Once again, I appreciate your time & help with this.
I wouldn't have thought the ECUs would be interchangeable due to the immobiliser. Thinking about it, a fault with the immobiliser would cause the lack of spark and noid. I know they usually also disable the starter motor as well, but a fault would change the way it responded.
I think a computer is needed here to live scan the ECU and see exactly what the little blighter is playing at before you go to the expense of an ECU.
