You should have received a recall to have the ignition switch replaced for free. Ignition Switch Recall 07 Sky's

Did you try to start after disconnecting the maf sensor? That will force it to use the manifold air density circuit. If works ok then, the maf sensor is probably bad. Expect a code to be set because of the disconnection. Or if the problem started after a tune, the tune might be the problem. I have seen other problems due to bad temp sensors.

I should have done that, but no. I disconnected/reconnected the battery, then disconnected the MAF, then started it. I was only thinking of testing to see if I would get a code for the MAF if it wasn't functional and I did. I am assuming that if the MAF is causing my issue, i would have had a code, but my reasoning could be off on that?

It may depend on how far out of range it is. It may be marginal.

You stated earlier that it won't crank until after you disconnect and reconnect the battery. Do you mean that nothing happens when you turn the key the first time?

Did you try reseating the connectors under the passenger floor?

A bad coil would set a miss-fire code.
