1 coil getting fire?

[sr240sx]

I have a 90 240sx. I pulled the KA for th well known SR swap. Since then nothing went right. It's been in my car for 3 months, i have yet to drve it. At first it would not rev up. I changed the mafs twice to get itfnially to rev. The problem now is it is only getting fire to the first coil. When i put te engine in it was getting fire to all four. I know because it idled good and I filed 4 sets of plugs. what is my problem?

check the cam angle sensor or the coils

all the coils are good. we checked all. It is just the first cylinder getting fire.

Then check the cam angle sensor. It is responsible for telling the ignitor chip which cylinder to fire on.

Also, the ecu won't send a spark if a specific cylinder isn't getting fuel. Check to see if the injectors 2-3 click or spray.
