Answer
Glenn,
You should check everything from the alternator, coil, wires and plugs.  Also check to be sure your ignition fusible link and EFI fuse is intact.  If your timing belt is off or your camshaft position sensor is faulty, that can also prevent a spark.  If you have yet to have those items inspected, have it done and hopefully you'll find the cause of the problem.
Good luck!
