Try to determine if you are missing spark, or fuel, when trying to start. Ckeck plugs or coils for spark, and check fuel pressure at the rail. Knowing which is missing will help to narrow down the possibilities.

When i jump to purple solenoid wire ,it turns over but no fuel and no spark. when I try and start by ignition it only has relay sound from glove box area. It acts like anti theft system is killing start sequences . How do I find out why its not getting signal? I am stumped as to what to check next. Help.

Ok let'* start with the easy stuff, have you checked all the fuses to make sure nothing shorted out when the rats were feasting? The other thing is do you have a check engine light with the key on? I'm wondering if the PCM is getting power. You said when you manually jumped the starter it wouldn't start?

My other question is where did the rats chew wires? Only under the hood or under the dash? Here is a test you can do in the ignition control module to check to see if your getting proper power and grounds there.
