I have a 92 civic hb I had the engine d15b7 swaped for a d16z6 at a local shop,( the engine was free) the guy who did the swap said that the engine started good after the swap but now it isn't starting at all. I had the engine, tranny, and ecu all swaped. the only mod I have on the egine itself is msd, he says it is electrical but he can't figure it out. the engine ran great before it came out of the 4th gen civic that is was in. the engine was swaped into that car first. Do I need a special harness or ecu mod, i am baffeled right now.
