Po335 - 2000 Hyundai Sonata

what maker of vehicle and motor are we talking about

EDIT Proton Arena 15i

something else is wrong
what ever is causing the no start does not have a code

yes PO335 right code and right part to replace

Code 123 is a problem with the throttle position sensor circuit.
Code 335 is a problem with the crank position sensor circuit.
And code 446 is for a EVAP control valve problem.
These components would need to be tested to find out if they are faulty.

Your fuel pump needs cleaning, I had same problem

PO335 crank shaft postion circuit "A" circuit malfunction This sensor is mounted on the left side of the engine block,Near the flywheel. If you replace this because its a code let me know if it worked and if you are getting more than 35 mph.

PO725 = Engine Speed Input Circuit
PO335= Crankshaft Position Sensor A Circuit

po843 is a hydraulic pressure valve in the transmission,that will have to be replaced.The code po335 is crankshaft position sensor a circuit malfunction.The sensor could be at fault here.

Cranshaft Position Sensor A Circuit Malfunction.did you reset your compter when sensor was replaced

CODE PO325 - KNOCK SENSOR. CODE PO335 -CRANK SHAFT POSITION SENSOR. CODE PO336 - I DID NOT SEE CODE PO336.

P0335 and P0336 Engine crank sensor malfunction
To test this code, have a visual inspection of the location and wirings of the crank sensor. If the engine has a cam sensor, you might mistook it as the crank sensor (it is a good idea to contact ATS that can research this for you). Check the sensor wires for insulation making sure it is getting a voltage signal as shown in the wiring diagram. Sometimes, the wires itself is soaked with dirty oil causing the sensor to fail. If OK, check the engine timing belt system for any slack which can also cause the sensor to throw in the code. If all of these prove OK, remove the crank sensor and check it for resistance as compared to the standard specs. Lots of times, if the sensor probe end is contaminated with oil or cracked, this can only be revealed after the crank sensor is removed
