the 1996 engine ran when it came out but in the 1999 it won't spark. also, i cant tell if the fuel pump runs because of all the bells ringing when the key is turned on..i've tried with both computers, same result. i've also tried both crank sensors. the cam sensor from the 99 wont transfer since its a dohc. i have a 2003 sohc engine to play with but i don't know if it can be of much use. if anybody knows where i should go from here i would be grateful.
