4th gen civic/D15B2 engine. I am getting a weak and intermittent spark when I place a plug next to the valve cover. I get 16 flashes (fuel injector) on my ECU. I changed them. I checked the timing, used a "working" distributor assembly from a friend's car, new plugs and wires, and it still won't start. It sputters for about 10 seconds initially, but flat refuses to try to start after that for about an hour. The only thing I can think of is that the problem lies somewhere within the wiring harness or the fuse/relay box in the engine bay. But I don't know which wire it could be so that I may trace it and find maybe a short or loose connection. Any help would be greatly appreciated.
