Alright here is the deal, I need help with picking the ECU. On the 4th gens just about any ECU fires up the car. Now on these 5th Gens its a bit diff because of the key. The date on the pillar states 7-99, ECU
# A56-P34-Z45 9719 Do I use all 13 numbers or the first nine numbers okay? Freaking car has no spark and I bought the car from a shop and ECU has not been replaced. I understand I have to go to Nissan to reprogram but trying to see if I need to fullfill those last four numbers or the first nine are okay? This goes for people that have fried the ECU and have bought a ECU from carpart. These cars are notorious for frying ECUs. Can anyone enlighten please that has replaced the ECU?

Did you exhaust all other diagnostics on the no spark issue first?

Not sure as far as the ECU identification numbers, but if you can find a 5th gen that matches your specifics (auto, fed spec, no traction control as you said) then you should be just fine.
