i just swapped ecus in my dohc zc and it wouldnt start, i reset it and everything but the distributor isnt giving any spark, so im getting a new one cause the old one was coroded anyway and i was just wondering if that doesnt solve the problem, what else might it be????

 

Check your grounds. Check them at the ECU first. If you have a computer safe test light, figure out which wires coming off the ECU go to ground.. if they read positive when the key is in the run position, you have a bad ground someplace. Otherwise, im guessing bad ECU.
