I just tuned my car to performance tuning with the superchips tuner, and drove it a few times and it worked great. Then I go to school, and I'm just driving and it turns off. I start it again, look under the hood, and it's idling really rough and at a very low rpm, almost stalling even though it's an auto.
So I tried to go home and had to travel very slowly, because if I pushed the gas, the rpm would rise then fall and almost stall. And now it won't turn over.
Someone told me there could be oils from the air filter on my mass air sensor, that's screwing things up......So I'm going to get some sensor-safe cleaner, but I don't know if htat is the problem. Could it be the fuel system?

Yeah, dirty MAF is not going to cause that much trouble. Plus you will not be able to get to it without a security torx bit.

Replace the stock tune.

I returned it to stock, and it still won't turn over..........Now I have the fear it is the fuel pump.

No dice.....
BUT, before I tried that I checked my fuel pump reset switch, and it was off, so I turned it back on, and still no start. And I checked the DTC's with the tuner, and it told me that the fuel pump drive module is offline....sooo would that mean that my fuel pump is broken?

sounds like the fuel pump is gone..

first turn the key from off to the pos. just before start. several times then go and depress the screader valve on the fuel rails and see if fuel squirts out. If it does not then you know you have a fuel issue.

from the way you describe it I think it's the pump itself.

+1 Sounds like your fuel pump is bad.This is a great
chance to upgrade your fuel pump to a bigger one.
