could be weak batteries. When trucks' up to temp..etc, the g.p. relay doesn't even come into play. SO, while ur waiting for the dummy "WTS" to go out, the truck WAS already for you to turn the key. Look up GPR LED mod. If lights not on, g.p. relay is not on. Now, when in the morning, when the WTS goes out, the gpr is actually still ON..(led light will indicate that), for an additional 3-sec-1min.
Mods easy to install, hit up radio shack for a 12v led.
