I Just Had The Engine Replaced. Now There Is No Spark. Engine Will Turn Over But Will Not Start. There Is An Autoguard Security System Installed, Could This Have Anything To Do With It. The Person We Bought The Car From Is Not Very Mechanically Inclined And Has No Clue. When We Got The Car, We Had To Get A New Steering Column. He Had Lost The Keys And Had Obviously Never Changed An Ignition Before. Please Help.

Welcome to AF !

Several things control that spark as thier could be other things also wrong and not working.
First you'll need to find out why you hav no spark.
Either the coils, ignition mod, or even the crankshaft position sensor could cause this. A bad ECM or that alarm could also keep it from starting.

Since you had troubles after the engine swap it has to be something that was changed or not connected properly.

Just a stupid thought but is the coil module plugged in. Is there spark to coil?
