I have just done a jdm p30 b16 swap in my 1990 acura integra. I am not getting any spark. I've double checked the msd ignition and the msd coil and those are cool. The only codes that the computer are throwing is for the ELD. Now I am not sure if the 1990 integra OBD0 even has this, and if that would cause no spark to occur. The only other thing that I could see it being is the ICM but they are like $120 and I didn't have any problems with that while the motor was in my 94 hatch.
