I have a no crank no start issue with my 09 GT, I got these codes before this happened

P1075, P0600, P1000, P2105 and U0300


The car was running like shit and misfiring very badly so I pulled it in the garage and shut it off. Scanned it and got those codes. I went to the house cause it was late at night and I wanted to get some sleep and tackle it the next day. I went outside and tried to start it but it would not crank. When you put the key in the ignition and turn to start the fuel pump doesn't prime and the dash lights won't come on… absolutely nothing happens. The battery isn't dead. You can lock and unlock the car too and the lights will come on. When you open the doors the windows will roll down slightly like normal and roll back up when you close the door. One thing that is weird is that when you lock the car the horn beeps really fast twice… it's never done that before and I've had it for two years. There are no blown fuses but there are some that aren't getting power. I checked the fuse box under the hood and the one by the passenger side footwell and no blown fuses… I am curious if the double beep means something because like I said it's never done that so I don't know if that is some sign of an issue… also before this happened I changed the fuel filter. When I went to plug in the fuel pump relay to prime the system I didn't disconnect the battery and as I was putting it in there was a spark but no smoke. I started the car and it ran fine… drove it for two days and then this all happened. In those two days, I put over 100 miles on it… I need help badly. I just don't understand whats going on. It went from running to a no crank no start within 24 hours and I didn't even move it out of the garage...

Since the windows roll back up, Im sure the battery is fine. (Or they would not roll up when closing the door.
The no dash guages is a concern. P1000 not ready for emission test. This would mean the pcm was recently cleared or flashed. Did a flash go bad on you? PCM is not happy.
You have one bank rich code, and a.throttle body actuator code, but neither would keep the car from cranking.

Before all this happened I had a cel for a bank 2 sensor 1 slow response so I cleared it, that's what that should be from. I have an SCT tuner I can read codes with and clear lights with because I had a custom dyno tune done.

Does the sct communicate with the pcm now?
If yes, I would try to restore to stock and then reflash the dyno tune. You cant hurt it by trying, you will just get an error message on the sct device if it cant communicate.

You can also try disconnecting the battery for 15 minutes. Might want to try that first before flash.

I can't do anything with the tuner because when you turn the key to the on position nothing happens, like it will not go into accessory mode even though the key has been turned.

That tells me the pcm is not communicating. Unook negative battery cable for 15 min. Let me know if it changes any of the symptoms.

Make sure wire harness is still fully plugged into ECM.

A bad ignition switch can cause the majority of the issues you are experiencing. No crank/start, no power to accessories or dash, no communication with pcm. And all kinds of crazy codes. Although the running bad prior to it going out is a new one for me.

Start with a load test on the battery. Power was lost at some point. That's where the P1000 code came from.

You also get a p1000 when clearing codes, OP cleared codes before the problem. P1000 goes away when emiision monitors complete.

That means nothing. First step in this diagnostic procedure is to determine if you have a good battery.

The batter is good, its less than a year old and I had been daily driving it for a month before this happened. I have no power to the ignition but I don't know how to test that... all I have is a test light and electrical is not my thing at all. I got an OEM ignition switch on order from work just in case that's actually the issue.

If all you have is a test light then ok. Put the test light probes on the battery terminals. Does the light glow brightly or is it sort of dim? If it is bright then the next step is to determine if you have voltage at the starter.

Throwing parts at it before a proper diagnosis can be a long expensive road to an empty wallet and a broken car. I'll look around for a diagnosis procedure that I have used. I'm not sure I have it with me. Your test light can do a LOT once you've learned how to use it. I'll dig around some.

Another thing. Make sure the battery is disconnected before you start probing around behind the steering wheel. Follow the discharge procedure. You don't want a face full of airbag.
