I have a 96 ex hatch wirh a b16a2 I changed the spark plugs and now the car will crank but it won't start I have checked the firing order and it's correct I know I have fuel pressure and I have spark and the car was running just fine before the new plugs I even tried putting the old ones back in and it won't start with those either it started one time after and it wouldn't rev past 3k it was like it was hitting two step at 3k rpms then after that it wouldn't start again please help!!
