i have a 84 toyota truck 4 cyl and it quit on me today when i was driving, any ideas what it could be, i have no spark to my plugs but i changed the coil and i still have no spark, yes i have power going to the coil but still have nothing coming out of the coil, totally lost. any help is greatly appreciated

 

Either the ingnitor (ignition module) or something I can't remember right now inside the distributer...

 

Check to see if you 12 v going to the ignitor ,it could be a power problem.
