Celsior electrical problems after battery swap.

[adz]

So after changing out a dead battery in my UCF11 Celsior for a brand new one I have no power to the car at all.I have checked all fuses under dash and engine bay with none blown.Checked power to all fusable links with a multi meter and have power there but nothing at ignition.I checked ecu to see if it had blown a cap but appears fine.I seem to have power everywhere but nothing in the car.Its as if no battery is connected. Car ran Fine no issues prior to sitting idle for about 6 weeks. I had changed out the alternater for a brand new one about 2 weeks before it sat for 6weeks and was charging fine but the old battery wasn,t holding it so that's why I got a new one. Could this be a factory immobilizer issue? Any help or insights would be great. Thanks

Don't know if it helps, but I stole this....

Anti-Deterrent ECU:
This is also possibility especially someone else drive your car. This is very common if you lend your car to someone. The symptom of this condition is "No noise or sound at all" when ignition key is turned. If this is faulty, the symptom will be the complete ignition kill. Therefore, you will not heard and clicking sound or engine turning at all. If this is the problem, you can easily reset the Anti-Deterrent by using your key. Stand out side of the car and close all doors. Insert the key into the driver side door and turn the key to clockwise and counterclockwise for three four cycles. Basically, you are lock, unlock for 4 times and this procedure will reset the anti-deterrent ECU. If this happen to you, its quite scary at first, but the solution is very simple.

i know this sounds stupid but make sure your terminals are on tight and clean, id get a terminal cleaner and make sure the terminals and the posts are clean, even though its a new battery.

get multimeter and measure voltage at battery terminals
sounds like u might have hooked up battery back to front and u have blown the main 100amp fuse
