I have an 03 Trailblazer LS, when you turn the key

Customer Question

I have an 03 Trailblazer LS, when you turn the key everything comes on, but engine. Just replaced the ignition switch, still doing the same thing, was thinking it had to do with the passlock, so tried that, well the problem is, when you turn the key to start, then go back, the security light goes off. Reading how to reset alarm, it says to wait for the security light to go off in 10-15 minutes, but mine is not staying on. Also, when you turn the key, you can hear clicking noises coming from under the hood. Husband says no power to the starter silenoid
