I've replaced the distributor the coil module the coil, ecu , what's next?

did you replace the distributor cap or the whole thing? Make sure your getting signal from the CPS to the ECU

So did your car die as it was rolling down the road or did it just not start one day? That's a lot of parts you changed out. Assuming the parts were good that you changed then a few things left that could be bad are the Air flow meter, fuel pump system, or your timing belt. Also fusible links and electrical connections. I would make sure your getting 12 volts to all the right places. Your best friend is the 1987 Nissan Maxima Factory Service manual. So I would get that off of eBay.

First time my car died it was the timing belt that went south. You can check that by seeing if the rotor in the distributor is turning as you crank the engine. Second time it would only try to start … problem was the Air flow meter. It was a known problem so I finally replaced it.

if it is the timing belt, might want to do check for bent valves...... if you still are not getting a spark or injector signal, I would start with pulling the distributor (the whole thing out of the head) be sure to mark it so you can get it back in right, with the key on spin it by hand and see if you are getting a signal if not check your CPS, which is a slotted plate with a LED and optic pick up under the spark rotor in the distributor housing.

is your ignition timing okay? could be out of whack if you replaced the distributor

otherwise as said the timing belt could have broke, best to take the timing cover off and see how the belt looks. Maxima VG30E are interference so theyre valve benders, if your belt broke youre probably looking at a new engine unless the one in a thousand chance that your valves didnt bend happens

Do you have spark? Do you have fuel pressure? Do you have Compression?
