sounds like a bad crank sensor that is the 335 code, the 1031 is a o2 sensor code, which would not affect the starting of the car

DTC P0335 CKP SENSOR (POS)

Component Description


The crankshaft position sensor (POS) is located on the cylinder block rear housing facing the gear teeth (cogs) of the signal plate at the end of the crankshaft. It detects the fluctuation of the engine revolution.

The sensor consists of a permanent magnet and Hall IC. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change.

The changing gap causes the magnetic field near the sensor to change.

Due to the changing magnetic field, the voltage from the sensor changes.

The ECM receives the voltage signal and detects the fluctuation of the engine revolution.


ECM receives the signals as shown in the figure.

So it has nothing to do with the fuel pump or anything like that
Nissan Mechanic: JOHN aka Eauto, The Car Guy replied 7 years ago

i highly doubt it

the proper testing procedure would be to check for fspark and fuel pressure

We will have to pinpoint what the engine is missing.


Spark


Fuel


Compression

 

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition.
