05 silverado alarm problems

i suggest you retest all wires. the only way the car will start when armed and not start when you disarm is because your starter kill is wire wrong.

it should be like this

85 - ground when armed

currently you have it wired for sure as

85 - ground when armed

Are you saying the actuators are aftermarket 5 wire type? If so, the reason they lock then unlock is they are adjusted incorrectly where you have them attached to the rods.

Lights won't flash, you aint telling us much. Are you using neg or pos lights? What do you have it connected to?

Again, we aren't mind readers, what do you have connected for door triggers?

Audiovox something.... ok.....

Avox starter kill, red to ignition or keyside starter, orange to orange, to two fat wires(black and WHITE/ black) to the cut starter wire, pretty simple. Are you sure you don't have arm and disarm mixed up? Disarm is 2 or 4 chirps, arm is 1 or 3...
