My 91 Civic DX is having troubles starting. When I turn the key, the engine cranks, but it does start. Also, as its cranking, I can hear little back fires coming from the muffler. I checked the ECU in the floor and the light would blink once, pause, blink 7 times, pause, blink 10 times, pause, blink 14 times, pause, blink 16 times, pause. Then it'll go back to 7 and do it again. Any idea what's going:confused: Thanks in advance. :D
