Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
I'm going to need to need some more information (that maybe obvious):
Which 3 cylinders are not working (which side)?
did you check for spark?
Are you getting injector pulse?
Fuel pressure?
which sensor was replaced?
