Did you check your injectors for proper operation before installing
them? They stick open (or closed) because of the cleaning solvents used
by overhaul shops. They should "click" when you apply battery power. If
they don't they are stuck, and you need to fix that (by treating them
roughly..). Its just a thought, it might not even be a wiring thing...
