2.2 engine swap

i took a 2.2 out of a 1996 cavalier that was knocking but ran and put a 1997 cavalier 2.2 in and now im not getting any spark to the plugs. the only thing i changed was the crank sensor because the 97 had two wires and the 96 had three and i never changed the oil pan which the 96 had a oil level sensor in pan. does anyone know if i have to change anything else, cant figure out why no spark to plugs.

thanks

did you try the ignition module/coil packs from the old engine on the new one?

got running today. it was the crank sensor. i spliced the plug for the one out of the 97 and put it in and it worked. thanks

i'm having the same problem, swapped 97 cavalier
engine for 96 but no fire to the plugs. did u have to replace the emc also? we can't reach the crank sensor, it is blocked by the wheel well, are we looking in the right spot for it?

i did not change the ecm, the crankcase sensor on the 97 engine would not plug in to the wireing on the 96 so i took the sensor out of the 96 and put in the 97 and i did not get any spark to the plugs,so i put the 97 sensor back in and took the plug from the 97 and wired it in the 96.the sensor is located around the coil pack.
