It would be strange that all 6 coils would die at the same time, but who knows. Before buying all new coils, visit a pick & pull junk yard and get a couple to try.
Several things to try is connecting the voltmeter to the trigger wire of a coil or 2 and crank the engine. Try both dc volts and ac volts. You should see the meter display "jump" if there is a pulse. It will not be an accurate reading but it indicates the ECU is sending the pulse.
You could also check the resistance of the coil(s).

I hate when newbies don't bother to add their location and start threads with just about zero details.
The devil is in the details and many what most would think are subtle nuances also have an effect.
Does your car have any alarm system?
So a little discussed corrosion thing happens to 4th Gens that also keeps it from starting. If you have Winter and Salt, or are close to salt water you are a little more likely to experience this.
Somewhere between the engine block and transmission, corrosion builds up and makes a sensor required for ignition, not read. Maybe a crank sensor. But the sure fire way to fix it IF it is the problem, is pulling the transmission and wire brushing the area clean. apply oil or a thin clear coat that bonds to metal well to keep it from happening again. But THIN so it doesn't interfere with the sensor reading again.
There's a lot of good and helpful 4th gen owners volunteering here. And some are amazing. But I bet none can read minds.

Original poster, don't do that!!!!
One of our members had a badly corroded negative battery cable . I mean the portion that bolted on to the engine. Once they replaced that, the car started and ran much better.

Attention Original Poster
I want you to read your first post.
Imagine that the people reading it mostly do know how to fix cars.
How are we supposed to understand what you are discribing?
You could have said that you have a (which year) maxima ( automatic or 5 speed with clutch)
I live at (location)
I'm having problems . There is no spark.. (how did you go about deciding that?)
I replaced both crank sensors (all but coils) , (What does that mean?) and the computer. (computer from which year car, auto or manual . ( There are several different ones. ) the wrong one won't play nice.
We need to know WHY you did those things. Did your buddy tell you to?
Are there any red lights on the dashboard?
Which ones?
Do you by chance own a 1999 Maxima?
The reason for a this picky informaton details is that enough of the right information can often make it possible for one or more of us to identify the problem. Often the same issue has happened to us.
Location matters. Salt leads to corrosion and
electrical issues.
Cars have different issues in cold or hot climates.
It is helpful to know where your car lived before you bought it. A car from a snowy area which now lives in Phoenix can have corrosion issues
The 1999 Maxima is infamous for alarm related issues. Because the alarm disables the spark.

Sorry JvG, sometimes I can't help myself! LOL
The thread title says 97 dead so I'm going to just assume it's a 97 cause that's all I got.
Some aftermarket alarm systems disable the spark, similarly to our famous 99 NATS. LOL
If that corrosion is there all the new sensors in the world won't help so I'm with you totally on needing A LOT more info! Following a logic ladder is how it gets done with minimal waste and costly parts change.
You know we're on the same page! Glad to be here!

KP,, yes, I missed one of the scarce hints we are offered. A 97. Duh. (Lol)
Thanks for pointing out what after market alarm can do to ignition systems. Like protecting the car from its owner just as effectively as from the car. thief.
I like some humor on this forum.

Coils can last a very long time. You could find others at a junkyard. Most would still be good.
