did you check for spark using the method i stated above? If not, try that first and that will eliminate the ecu possiblity... by checking the spark in ur wires that will narrow down the problem a bit, if you are not getting any spark at all with that method, check ur ignition relay, check ur dizzy car and ur dizzy rotor and make sure they are not corroded or wore out, if the relay is good and your cap and rotor is good... your internal coil may be going bad or may be bad already. do the spark test first, if no spark check cap and rotor and ignition relay, if all good... check your internal coil.
