ka24e running on one cylinder

[paydirty]

Hey guys,

I've got a '90 240sx that I am having a really hard time trouble shooting. The car is only running on cylinder #2. All of the injectors are in working order, the car has excellent spark in all four cylinders and I did a compression test with all four cylinders coming out excellent. What would be the next step in getting this thing to run right?

Forgot to mention the timing is set correctly as well. I was thinking it could be the ECU, I have noticed that the spark plugs in the non running cylinders do have gas on them but they are not soaked.

Any help would be greatly appreciated.

here are some easy things to check (always start with the easiest first)
1. new spark plugs.
2. Compression test
3. Swap injector plugs

I see you did a compression test already, good thinking.
