tb45e has no spark

[Off Tap]

Have been meaning to update this post for a while- I have sorted the problem. A few weeks back I came across a second hand factory ecu(same year and transmission) on ebay for $110. I was hesitant at first whether to fit it or not as I knew it would induce a NATS fault and if it did I would be another step back from sorting the defect. Eventualy I grew some balls and plugged it in and frig me dead the beast started- ran sweet for approximately 10 seconds and then died- started it again same thing, ran sweet for 10 seconds then died with engine light flashing. I didn't even bother checking the code as I knew it would be a NATS fault, the main thing was the spark was back and the main defect was solved- it was a bad ecu(it does happen).
So at least Nissan have allowed this logic for a part swap test to be carried out before pulling the plug on an unknown NATS part- for those who don't know NATS for the TB45e ST consists of your chipped key,the NATS immobiliser unit(which is a small box which sits on the back of the ignition barrell) and the ECU and these three components need to be registered with each other before you can drive your car without it stalling. Now when replacing one of these parts from original without reregistering it the system willl not work- at least not for more than 10 seconds max.
Now if you end up in this scenario- which by the way I am only vouching for an ECU change not changeing the other two NATS components you can take your vehicle to Nissan and have them reprogramme it(bet it would not be cheap) or if your in Brisbane you can ring Jonathon from Prime Locksmiths- 1300890540 and he will come to you with his advanced diagnostic equipment and reprogramme the ecu,immobiliser and key to match- as I said this is for an ecu change, I don't know if the immobiliser unit can be reprogrammed if you change that individually. Hope this info can be of use to some people.
Back on the road so happy days
