Need to know whats wrong with the ckp po335

(2000 Nissan Sentra)
put bad gas in it one time bucked and jumped then died in the middle of the road. well put some cleaner for the gas injector and carbs in the tank and it ran great for about a month after that.Well all of a sudden in the beginning of October I went out to crank the car to get it warmed up well it started up but only ran for only about five mins cranked it again and it stay started. well i did my few runs and was headed back home then it just died out of no where on the railroad tracks. When it died it felt like i just let off the gas pedal but i didn't well it gave the code i think po340 i think for the camshaft position sensor and po335 for the crankshaft position sensor well we changed the cam and it ran great again smoothe as ever but then three days later started bcuking jumping and dying again in the middle of no where. so we decided to change the crank well upon changing the crank we couldn't get it to come pass the Oring so it would come out of the motor and we puled rlly hard on it and the pigtail connector clip broke.... just the clip part the rest is still fine and I'm sure we could probably hook it up somehow to stay on there but then when we finally got the crank almost out of the motor the end piece that sticks out of the car that you connect the connector to on the sensor rips off but from the Oring on it still in the motor. i mean we couldn't done nothing bad except brake the harness the sensor was already bad well now we have replaced both of them and it wont start period now it will crank but no start... I'm just so frustrated i need help!!!!!

So you finally got ALL of the old crank sensor out of the engine and replaced it AND the wire connector but now the engine will not start . Correct?

Yes finally got all of the old crank sensor out and put and new one in along with replacing the cam sensor again bc Autozone said they had to be replaced at the same time. But to your other question no I have not replaced the wire connector on it the wires are still great on it and the connector is not broken it's just the clip part that is. I put zip ties to hold it on the sensor real tight (I know super country and ratchet lol) but it stayed on there tight and still no starting.. im really not sure what to do anymore ive checked wires tested the sensor in it now and the voltage is right where it suppose to be. ive checked the fuses tried to reset the ecm i didnt break anything and i have servie engine soon one the dashboard so im at a lost. i dont think its the ecm becuase if im correct it wldnt do a diagnosis if it was the ecm right? it wouldnt be able to read and like i said it still says po335 but there is fifteen different things it could be with that sensor!!!!! i just want to bust all the windows and set this thing on fire!!!!

I think you should replace the crank sensor wire connector/pigtail .. While pulling on it, very possibly could have damaged the pin connectors inside the connector... Suggest ignition spark test also.

Ignition spark test? is that when you test the spark plugs and coils? ive tried that to if that what it is. if not then i am not quite sure what to test lol kinda just been getting all my info from google and people doing Q&A on other chats. Also not to be a pest but i have called the part stores around where i stay for the pigtail connector and noone has it. is it just a dealership item?

When you did the spark test .. Was spark present?
on December 19, 2016
Yes spark was present in all four

IF it is 'still' getting spark then the crank sensor is NOT the problem!! .. Start looking into the fuel delivery system!
You'll need someone who is familiar with testing for no fuel to engine as this test 'can' possible be a fire hazard. Ask a car savvy friend to help you out.

We tested that to.

Ok, here's the deal : IF an engine has got proper spark ... Fuel delevery AND Compression .. It has got to start up and run - period! .. You need a MECHANIC to help you out hands-on .. Good luck!

Fuel delivery is fine. Did a pressure test and all that. Spark is fine. did the four plugs and coil test. But compression what the hell do I do for a compression test?????? Like I said before we changed the crank it was running and driving But it was dying randomly but it did it everyday multiple times then we changed it now no start. But we haven't did comlression test or anything. Everything I've read has all came back to over stretched timing chain.
