I have used the immobilizer bypass DEI XK05, and wired it up correctly, but when I activate the remote start, the starter cranks, but the car won't start. It just cranks and won't start up.
Tried using firmware PKTI using the wiring as noted below.

When using the PKTI the car will start and shut right back off. If the key is in the ignition the car will start and stay running as it should. So it seems as if the code is not programmed successfuly.
Tried using firmware PKT2 using the wiring as noted below.

When using this firmware scheme the car just tries to crank, crank and crank. If I leave the key in the ignition the car will start and then die. Strange because I can still start the car fine with the key.
Wondering if I have a bad XK05 module. Can some please help me resolve this issue? Help would be greatly appreciated.

I would go W2W mode. I have used the XK05 with .5PKTI firmware successfully in W2W mode many times.
Re-Flash the module with .5PKTI firmware to reset it. Run the GWR wire and the +12v & ground seperately. All your wire colors and pin locations are correct.
Re-program to the car and try a remote start. ------------- Soldering is fun!

With the bypass unplugged and the key in the ignition the RS should start the car. If it doesn't there is a problem with the RS install, not the bypass.

The car will start with the bypass unplugged using the PKTI firmware.
The car will attempt to start with the module unplugged using the PKT2 firmware but will not start because the wiring scheme for this firmware will leave an open on the IMI if unplugged.
Okay guys. My car is currently wire to use the PKT2 firmware. Either should work, but I am tired of switching back and forth on the wiring.
I would like to use the PKT2 in junction with D2D. This should work but its not.
Has anyone installed a XK05 with PKT2 using D2D successfully?
Has anyone ever received a bad bypass module of this particular make and model.

If I am reading your chart correctly from the first post, the green keysense wire from the X05(PKTI) is not supposed to goto the security LED. It goes to the keysense wire next to the key cylinder - (Black). This is not only required to disarm the factory alarm, but the X05 needs this wire connected in order to program correctly. If your car does not have a factory alarm, you can either leave it connected after it programs or disconnect it after programming. But once again, during programming it needs to be connected correctly.

Frank,
That was a copy paste error. I did have the Key Sense wire connected to the two pin connector on the black wire of the ignition switch for the PKTI. For the PKT2 this is not required. This is the illustrations for the PKT2.

Also, to inform everyone I have removed the factory alarm from the 06 Scion TC.
I have installed the Viper 5701 and 530T window module.

Okay,
For some reason I think its just not programmed correctly there are some things that are not specific in the PKT2 manual. Could some post step by step directions that are specific and are not copy paste. Thanks.

i agree with kreg's earlier comment on the W2W connection. sounds like a bypass issue and u cant trouble shoot d2d.

Okay. I am going to switch from D2D to W2W. I think you guys are right. When Brown status wire recieves the GWR (Ground While Running) Output from the Remote Start Module this should activate the Immobilizer Overide.
It could be possible that my D2D is not sending this output therefore the module never sends the programmed code. However I will verifiy with a DMM as well.
I hope this fixes the problem. I have been starting my car then activating RS and removing my key in the mornings. LOL.
