02 max in need of help

[al odom]

i have a 02 maxima and the service engine light is on i checked the codes and they read PO335, PO725,PO725pd,335pd. the problem is with the crank sensor when plugged in the car cranks but runs at a low idle and with it unplugged it turns over for a couple seconds and then crank. it runs fine after that. i was told that a new motor was put in. could anybody give me some help solving this problem
