1999 Chrysler Concorde started and wont start again

I am not a mechanic today but. Now retired from that the best I can offer is my story of the neighbor that gave me her car. I offered her 4k for it four years earlier but she was very attached to it. Having just spent 30k on a new vw bug she was sure her 95 Dodge Shadow would be worth more than 4k. The short story is that when the city said it can't stay in her drive without plates, and four years had passed, she gave it to me. I diag'd for a few hours and after pulling the plugs to dissolve the rust inside in a Marvel way, and tapping the pistons with a wooden dowel, I got it to turn freely. Still no spark though so next I figured out that the small pcCard that provided security was not more than a jumper in line with the ignition ckt. Like a second key but could be defeated with little effort. The solution was to trace the wires back from the "secure key" to the column harness and jump the socket to overide it. My problem was the PC card contacs were coroded. Just plain copper, no berillium or gold plating here. Glad I don't know how much extra it cost for that thing. Hope this can help y'all.
