2007 GMC Sierra Remote Starter Issue

I have a 2007 GMC Sierra SLT that has pretty much every option on it except a coffee maker. Everything has worked great until a few days ago when I went to start the truck with the factory installed remote starter. The truck flashes the lights to say it got the signal, you can hear the fuel pump go off and that's it. No injectors going, no starter. I tried both remotes and both do the same. Would anyone have any ideas as to where to start looking? Thanks for any help.

Good morning,

I tried looking into my resources but wasn’t able to find any troubleshooting guides. My next recommendation, then, is to consider bringing your vehicle into your servicing dealership.

Best,

Is a SES lite on? They won't remote start if certain codes are set.

I just found that out from my dealer, if you have an engine light on, the remote starter will not work. I popped out a P0449 code and a P0455 code. Does anyone know where I should start looking to get rid of these codes?

GM has a bulliten out to replace the evap solenoid for these codes.
