Nissan Sentra does not start

Hello, I need them to help me, I have a quite old Nissan Sentra (1986) Carburado, the problem is that it does not start even though it is Starter, it is fine since with the uncovered distributor I have seen that it turns when trying to turn it on, just to verify that it is fine, I have changed the spark plugs, the coil, the cables that go from the coil to the distributor, the distributor cover [IMG], the rotor. I have also used the batteries of other cars to rule out power problems. I already checked under the carburetor and there is a presence of fuel.

Thanks in advance.

Make checked if they get current to the spark plugs because it can be a current cut that you have.-O you check if you have any type of alarm with a boltering

It seems to me that the problem is in the ignition module under the distributor, the problem is the optical sensor that is the piece under the distributor and that is the necessary piece for this repair.

(eye: this controls the fuel system too)

we saw each other

Look there is a very big problem with these systems, I recommend verifying the regulatory box and it will be incorporated. Something similar happened with a chevette and it was a regulatory box, Saves can prompt throwing direct fuel to the carburizer to see if it starts thus we discard several things, you have it and tell me how it went or what iso the vehicle.
