You say fire goes into coil? Generally when talking about fire we are talking about the spark, not voltage to the coil. So do you mean you are getting voltage to the positive side of your ignition coil or do you mean that the center wire on the distributor has fire when pulled loose from the distributor cap and checked(would mean you have fire coming out of the coil). If the latter then take off the distributor cap and check the rotor button. If you are getting voltage to the positive side of the coil and you've already replaced the icm and ignition coil coil I would suspect you need a crank position sensor. Check to see if you are getting ground pulses to your negative side of the coil while turning over the engine. If not then it's probably the crank sensor seeing how you've already replaced the ignition module and ecm.
