ok.. i newly rebuilt B18B1 LS motor (new pistions, rings, con rods, Valves, Spings, and all Gaskets and Seals) the motor will start, but the #3 cylinder wont fire, I have swapped injectors, swapped another LS ECU, checked the compressions 182 PSI(new should be 182-183) timing is right, Spark plugs and wires are new and Dizzy cap have been swapped with a friends. I checked the voltage on the injector plug, no diffrent from the other 3. I dont get a Check engine light, but idle is way low or way high(1300 at high mark,450-500 at low mark, it wont even out no matter how i adjust the Dizzy. and if you pull the spark plug wire off of that cylinder, nothing happens. I originally adjusted the valve followers, and ther has been no change. I looked into the cylinder(with the spark plug out) no marks or scars on the piston..
Any ideas? any help would greatly be appreciated.
