Hi,
Is the vehicle running properly? As far as the check engine light, that indicates there are diagnostic trouble codes stored in the PCM. We need to have it scanned to determine what codes are present. They should point us in the right direction.
Here is a link that shows how to scan the CAN system:

If you don't have a scan tool, most parts stores will check it free of charge.
Let me know if this is something you can have done or do yourself.
Take care,
Joe
