Hi, i just recently replaced a flyweel on an automatic 02 kia Rio. and i couldn't get it to start. before i did this i would start but the flyweel teeth were GONE.. i know every thing eclectic is plugged in where it is supposed to be.. now we belive it is the crank sensor i the front of the transmission case it reads the flyweel holes does this have to be set or timed to start? also there is one longer hole then the rest idk what this is for? i need to fix this asap this is my only car i can get to and from work so please get back to me
