Hey everyone, I need some help. 2003 trailblazer. I picked it up broken, and put a battery in it, dashboard came on with ignition key, try to turn it over, and nothing happened. When you let go of the key, the dashboard no longer lights up even after cycling the key off and back on. I replaced the sealed circuit, starter solenoid, and ignition switch. The dashboard will not light up unless you disconnect the battery and reconnect it. Every once In awhile after I’ve disconnected and reconnected the battery, it will actually crank the motor when you cycle the key, but once you let off the key, the dashboard won’t light up and it wont crank. Once you cycle the key and let off of the key, both sides of the solenoid next to the battery have voltage, which isn’t supposed to happen. Once you disconnect the battery, and reconnect it..there’s only voltage on one side of the solenoid. Someone help figure out what’s going on so I can get it cranking correctly and move forward with this project!
