I have searched but have yet to find a solution...after 2 hours of riding fine no issues, my son added gas and tried to ride, but it would not crank. I have spark, changed plugs, fuel injectors are working. I checked timing as per manual, checked CPS, ohmed at 962 and 4.1 volts and cleaned map sensor. It will run if carb cleaner is sprayed into throttle body. I had no codes present until I disconnected the CPS, now I have P0337. I am out of ideas.

Well P0337 is the code for no signal from the crank position sensor so there is a problem there. Pull and check it. Also work the kill switch a few times and be sure it's in the run position. 

I checked the crank sensor, it ohned at 962 and voltage was 3.7-4.1. Still will not run.
Is there anyway to clear codes without pda?

Prior to 2018 they didn't store codes. If it has it, the issue is still there..for some reason. Pull it and inspect the end and rotor. Some have had stuff get thrown up and between the two.

P0337 code means that the vehicle's crankshaft is suffering because of low voltage.

There could actually be a number of causes behind this code, but the most common are:

The CKP sensor has malfunctioned or quit working altogether
The sensor is no longer installed/aligned properly
Loose/weak contact/connection
The starter is defective (large current draw) or the battery is weak/dead
Electrical problems like short circuits

Need to find the reason for the code and correct.

How did you determine the injectors were working? Bench testing or in the machine while cranking the engine?

Engine failing after adding fuel makes the added fuel a suspect as well, especially if it runs with starter fluid or carb cleaner. Best to drain and fill with fresh known good fuel.

From the service manual for 2017 Z800:

mboyet68, this is all in the manual I sent you.

Ah, he has the manual!  oops.

What did you clean the T-MAP sensor with?

[2015 Z Force 800 53/Trail EPS]

Ah, he has the manual!  oops.

Just send the link yesterday afternoon.

Yes I did receive the manual, thank you for sending that! Now i know i still have a crank sensor problem. I checked it again this morning, it it ohmed at 967 with 2.7 voltage while spinning the engine over. I worked the kill switch numerous times as well.
I will drain the fuel and add what I know is good.
I cleaned the map sensor with electrical contact cleaner and allowed to air dry. I only pulled #2 injector and saw it was spraying fuel.

It was the gas. Thanks for all of your input and help!! Greatly appreciated!

That's great news!

The CPS code went away?

Now you are going to want to replace the fuel filter.

I will be replacing the fuel filter, and all codes are gone.
