Micra is now running as expected, the misfire and stutter traced to the distributor, replaced with a new unit. I must admit I should have paid for the diagnostics to start with and probably would have traced the fault. The red herring in it all was the ECU failure on the NATS, which threw...

Time to revisit this post! Car is now running again, the fault codes 141 & 142 seem very much NATS related. The awesome ED sorted out a ECU for me, at a very reasonable price, basically he re-mapped a K11 pre NATS for me so it just plugged straight in and vroom! The car still has an...

Thanks Frank, only 3 in mine, 3,5 & 6. This is driving me crazy as car is not worth that much, but has now got to me and I don't like being beat by an inert object! It is one of these times that the basic service I gave it, plugs, filters, oil and timing should never have caused this...

Thanks for the reply, it's the 14 pin one Frank. The symptoms started with hesitaation and loss of power when warm, reason for the throttle body initially. I am not familiar with the Micra relay layout or fuses (with the exception of where they are labeled =) ), what are the three that are in...

Swapped the distributor over and still the same fault, non starter. Anyone know what else controls the pulse on the injectors? A relay I am missing that could be faulty, last ditch attempt before I drop it off at Nissan. Cheers Jim

Thanks for the replies: Checked the fuse holder and the fuse all ok, getting 12v at the injector plugs. Fuel pump is running ok, loads pumping out of the filter. The fault code is 141 & 142 Frustrating fault, my wife bought it from a local garage "as seen", it seems that it might...

Update.. Changed the throttle body over to the old one, same result, both run with fuel poured in, engine fires and runs. Checked all fuses and all are ok. Engine codes remain the same, ECU s working as identifies self created errors with correct codes. I think it is now down to the...

Hi Folks I have now ended up with a non starting micra, with error codes 141, 142 & 144, yes thats the codes so not the usual 2 digit ones. Turns and has a good healthy spark at all cylinders, but does not fire, fuel ok to the rail, injector plugs reading 12v but no pulse. I have fitted a new...
