I just rebuilt my 2001 B18C integra gsr. It was miss firing on cylinder 1 &3. Turned out to be a burnt and cracked exhaust valve on #1. After putting engine back in it started, reved fine,but was running rough at idle (going up and down)and sounded like a misfire. the CEL codes showed (5) misses on all 4 and all missfire. I rechecked and adjusted the cams slightly according to the workshop manual.Now it wont start. I checked the all functions in the distributor and all checked out. If i take #1 plug out and crank the engine grounding the plug i get a few sparks then no sparks. Its that normal? All cars I usually work on have limited electonics on them and will fire a spark continiously.The only other variable I changed was I bought a used knock sensor as I broke the original taking the motor out. I assume if this was bad it would not cause the motor to not start. Any other ideas. This is a real pain after spending all that time on the rebuild. BTW-It has all stock parts in it.
