Put some bad gas in it one day and it started bucking my dad who is not a licensed mechanic told me to put some fuel injector carburetors cleaner in it. Did that ran smooth for a month or two. Drove it to little Rock it drove fine there and back. Two or three days went by and it was still driving excellent. Then I went outside one morning this past October to start the car to let it warm up cranked right up and then died five minutes later. I thought it was just the battery so got someone to jump it off same symptoms started up about five to ten minutes later so I tried cranking it one more time started right up and didn't die anymore well this happend for the next couple of days and then it started to die randomly like if I were to take My foot off the gas pedal and it jut would die all the lights were still on but it was like if I were to slow down or come to a stop it wld just die without a warning.we got a code for po335 and I think it was Po340 or whatever the camshaft sensor is. so we replaced the cam and the sea light went off and it drove great for three to four days then it started dying even more and at the worse times even when my foot was on the gas pushing it giving gas it still died and the ses light came back on but with just the crank position sensor code this time the po335 so we decided to do that well upon changing that trying to take it out was a pain we wind up pulling the part that covers the female and male metal parts on the inside because we couldn't get it to pull out of the car due to the oring well we took a tiny screw driver took it behind the oring and started prying it out and atlast it came out it looked nasty looking but I assume that's what it is suppose to look like. So we put the new one in bolted it all back up and no start so we thought ok maybe it's defected so we took both the cam and the crank back because we were told that it's best to replace them at the same time so doing that we got to new sensors tested them with the multimeter and they both have great voltage. Put it tried to crank it no start cranks but wont start cam sensor still has no code popping up but the crank still has the same one po335 crankshaft sensor  circuit malfunction A well we weren't told that the cam sensor had two cams one is bent and goes in the motor where the oil and stuff is and the other is straight and looks just like the crank sensor at the bottom of the motor on the cylinder block by the starter so we replaced the straight cam and still no start we still got the po335 crankshaft sensor circuit malfunction A so we looked at the wires it's fine no corroded or torn wires from the harness to the connector the only thing is the connectors harness clip the little green clip is broken but the harness still goes on the crank sensor how it's suppose to idk what to do anymore and buying all this crap I'm becoming poor lol!! Help plz!!!!! I don't want to take it to Nissan and them charge me for something I can do myself!!!!! It's a Nissan Sentra 2000 1.8 gxe
Vehicle: 200 Nissan Sentra gxe 1.8 litter

When there is a no start condition you can set a camshaft code condition, Even with a faulty camshaft sensor the engine would start, you would not accelerate good, but it would start, The one area that needs to be check is the fuel pressure the reason I say this is you took the foot of the gas pedal and the engine died, fuel pressure should be suspected, if you have carburetor cleaner or brake cleaner spray it in the intake and se if it starts, if it does it fuel related.
