k well i have a b18a1 swapped 91 civic now it ran fine till 2 days ago i changed my fuel filter and replaced sum coolant hoses now it runs on 2 cylinders i have good compression getting power to the injectors i have good spark changed the distributor my dad rewired the whole engine harness to take out any bad connections as a cause so now my dad is thinking its either the fuel pump or the map sensor if anyone has encountered this problem i need help please
 
no cus i switched the injectors i took the 2 outa the non runnin cylinders and put them in the running cylinders andits still the same 2 cylinders
 
i had this problem check the injector wires where it meets the plug to plug into the injectors caused mine to run on 3 cylinders, could also run the car then shut it off and pull a plug from one of the bad cylinders and smell for raw fuel and its probably a problem with the wiring for the injectors
