Frank, dont think so the car has an after market immobiliser which the company told me how to test with no problems but out of desperation I disingaged the whole thing. The engine turns fine, I have tested the fuel pump using a battery and fuel pumps and returns to the tank,but when the ignition is on and turning the engine, no fuel is pumped and no spark at the plugs.The first time I took the throttle body off was because the car kept choking then came back to full revs, I cleaned the unit and put it back on it started ok but idled too fast so I took it off again and found that the O ring on the air valve was twisted when I put it back it would not start at all. I thought I had damaged it so got a replacement from the breakers but still no life . Thats when I started tracing the fuel, then the spark with no success. Changed the engine unit relay, checked all fuses and links but nothing.I have just had a new clutch fitted and its been really reliable for the past years so dont want to give up on it.
My old QX had a Nats system so I am sure the micra is not fitted with one. I will check in the morning. Thanks for the reply.
