2005 Dodge Caravan Won, t start after sitting

Just curious, key on, no crank, what is reading across battery posts. When you turn the key on, no crank, there will be some voltage drop, then when you turn the key to crank, there should be even more voltage drop. My thinking is the voltage readings you gave are too high, engine cranking? The relay may not be energizing? Your security system may be causing an issue? The ground for coil side of relay, is grounded by the pcm.
