Lets play "Diagnose My Motor!!"
Long story short, me and a friend of mine are swapping a 95 KA into my 91 240sx. Everything went pretty well until time came for her to fire up. she runs on cylinders 1, 2, and 3, but 4 is dead. Compression was like 145 (low, but still able to run) and she is getting spark. We thought the injector may be bad, so we swapped it out with one of the s14 injectors to no avail. Im going back tomorrow to HOPEFULLY finish the job... Any suggestions?
Copper plugs check for GAP if not firing return it.
Brand new platinum or Iridium not firing return it.
I just hope your not using the same wires from your old engine.
Also use 10w40 motor oil on low compression piston rings, it will slightly raise compression.

All the usual ignition tuneup parts were changed to brand new ones and im 100% positive im getting spark. The onlything i can think of is that we replaced a bad injector with ANOTHER bad injector?
