2001 Buick Lesabre passkey 3 ..security light stays solid even after half hour of ignition sitting in on position.
Have you tried another key?
Starter is good..
How do you know?
fuses are good..fuse panels are hot..
They shouldn't be hot...
crank turns manually
Do you mean by turning the crank bolt with a wrench, or jumping the starter?
..battery is not corroded..lights on dash and radio come on but when turning key to run position with ignition everything goes out.
That is a normal function when the key is in the crank position....
With that light on constantly, it's telling you you have a problem.....If there is nothing wrong with your key, then even though you leave the ignition on for more than 10 minutes, and the light stays on, means you have a problem with the system.......does this vehicle have an aftermarket remote start in it? If it does, that is where I would be looking first.....seen a few wiring problems caused by add on systems.....
For the most part, these systems have been pretty foolproof.......outside of a visual inspection, not much you can do, without a Tech II scan tool and diagnostic charts.....
