Engine problem
2002 Nissan Altima 4 cyl Front Wheel Drive Automatic 58,000 miles

I have a '02 Nissan Altima 2.5 SL 4 cylinder

her is my problem hard time starting my car cold or hot check engine light is on reads Po335 (crankshaft position sensor malfunction) also (can't remember the code #) vehicle speed sensor Steps I have done 1. Change the crankshaft sensor 2. Clear the codes turn the car on and no check engine light but I plug in the obd II (from auto zone) and I still have one code present Po335 drive the car for about 30 min and then the engine light comes on. I plug the scaner after I have driven the car vehicle speed sensor code is present again 3. Change the plugs 4. Check fuel pressure its at 50-51 psi (good) 5. I tried checking the spark from the wire I don't have the right tool for that so I used a screwdriver to metal I had some one crank the car but the time frame were its having trouble I did not see spark till it actually started to run and I tried to do the same to another wire but I could not do it because of room

once the car is on and running I have not had it die out on me drives like new

Engine may be starting to go. Also it may be as easy as to much oil or not the right type
