Hello, avenger owners out there: tryna troubleshoot a 2010 avenger r/t. It won't crank from inside the vehicle. When I turn the key to on position, the red security light comes on solid for a second or two, then goes out, then about 3 or so seconds later, begins flashing. Does this mean the antitheft system is keeping it from cranking? I changed the engine in this car, after it had sat awhile. Owner reported no previous problems starting the vehicle before the engine swap became necessary. HHEEEEEELLLPPPP!!!!
