I am led to believe that from 2000 the ecm of the mazda cars could be programmed for better performance with the use of a laptop with a special mazda program
try talking to performance shops as they are most likely to have the programs or can advise if it is possible to reprogram

Let me get this straight, you took your Nissan to the NISSAN dealer (who has extensive data and resources) and they said you needed an engine due to the timing had jumped and you declined due to the $6500.00 price. So you took it to the independent guy (local mechanic) that is guessing and throwing parts at it and most likely making it worse because you only needed an ECM that the dealer said was ok, 2 cam sensors and 3 coils (but hey its cheaper than an engine). So now you have a used ECM that doesn't belong in the vehicle that you most likely didn't need and are awaiting the correct one from Nissan. You now have or will have 3 working ECMs, 4 good cam sensors and nine good coils in a van that will still not run. Ok and now you think that the independent guy (local mechanic) doesn't know what he's doing and you want to know if anybody knows a good mechanic. Whatever gave you that impression?? I know now what the problem is.....it's you. You tried to save money but it didn't work. Hopefully you didn't do any further damage but who knows. Get your money back from the local mechanic and take your van to the dealer to get the engine you need before someone else takes you for a ride or damages your vehicle further.

I recommend getting a repair manual from an auto store for your vehicle. They run $15 to $20. It will tell you exactly how to do everything you asked and also give you the values that should be expected. Hope this helps.

Sounds like you got two wires mixed up. Check your firing order. If not that, then you dropped a spark plug and flattened the gap. If it's a V6 the firing order is 165432. If it's an 8, it's 18726543.

you can do it your self but the computer/ecm will need to be flashed. any Mobile lock smith can re flash the computer to your key for a small fee

I had the SAME thing with my car!! Remove your air bag module its a grayish looking box that deploys your air bags, my air bag light was on but it was on and off. I pumped gas in my car one night and when i went to crank it my car cut right off after a split second. My mechanic took time on it but discover that it was a secrity issue. He removed the air bag module and presto it fired right up. I thought it was a fuel filter or fuel pump. It was just the air bag module, people freaked out about it once i told them what it was....it should be under the passenger seat, i believe u may have to take out the seat to get to it.
