Car won't start after changing ignition

[lunatyk]

So my car was stolen and I just replaced my ignition because it was ruined. Now that I try to start the car up by jump starting it, it won't start; I have no power either. I don't know if I'm suppose to do something else in order for it to start up...?

If it matters, I have a s14 and have a viper aftermarket alarm installed (might affect it?)

Thanks in advance!!!
