96 lumina 3.1 help

[dampontiac]

So i got this 96 lumina for free

what was reinstalled in the car was a 3.1 from a 95 pontiac grand am, is there a way to make everything work on the motor? it doesn't run and it is throwing about seven(7) check engine codes
if anyone has come across this issue i would be in great graditude of you! if you can give me any help.

These engines have different pcms to start with, harnesses may be different also.

Would i be apble to get a pcm for a 95 grand am and put it in the lumina??

If the Grand Am motor is a roller rocker arm engine, other than a sensor or two, it should work. If the engine is a ball and pivot style rocker engine, they are not interchangeable, and you will spend more money trying to make it work than the car is worth. A Grand Am PCM will not work in your Lumina.

I am not sure what the differences are between a roller rocker arm and a ball and pivot style. is there a way i can tell by looking at the thing?
and do you know what sensors i could change if i do have the correct one?

Externally, you can't tell. You'll have to pull a valve cover and look at the rocker arm. If it has roller bearings in the center where it pivots, it's a roller type and if not, it's a ball and pivot type. Sensors that may need to be changed are the CTS, oil pressure switch and TPS.
