hey guys i have a 91 hf and a 91 si. the b16 was in the hf, running perfectly no ignition problems. i swapped the b16 into the si and now i get no spark whatsoever. everything else works fine. we took the d16 out of the si and put it into the hf and it is having the exact same problem. both cars ran perfectly before swapping. i did a search on the site and couldnt find any answers so if you guys could give me some info it would be greatly appreciated. i have already checked all fuses and wiring. everything is good and connected. how do i test if my dizzy is getting power?
