here's another problem i had with ignition. the engine started hiccuping again (see my 88 daytona ecm post) then wouldnt start ne more. would almost crank up but would not quite make it. thot my hep was going out again. changed it. still no start. timing light showed only 3 & 4 cyl were firing. pulled hep again and accidently noticed the rotating distrib plate was loose (the thing that disrupts the magnetic field near the hep). plastic rivets were not firm. changed distrib. all is well again.
