swapped engine and it started up. was running rough changed back to the f22a4 ecu. Still running rough. Put new exhaust on and now it will not run. Turns over gets fuel but no spark. Plugs were fouled so changed them out, also put in a new ignition contrl mod. in dist. When I went to get parts all the 92-96 prelude dist. had a 5th wire for an external coil, the one I have has only 4, with coil in the dstribu. The engine is a H22A from Japan from between 1992 to 1996. My harness from my car mathched up. The engine originally in the car was a F22A4 if that helps. I also have not hooked up the v-tech harness, but I have been told that it should not matter just to get the car running. Any help would be great.
