You need to find out why these Monitors aren't ready. The check engine light has to be on. There's isn't enough information in your post to truly help....so I'll do my best. I'm guessing you have an evaporative emissions DTC that is set, also preventing these monitors from passing. You could also have some oxygen sensor DTCs as well. You need to see if you can have any pending or history DTC's pulled from the the engine control module and post them back here. We can go further then.
