If you checked the wires and the computer, the onlything left is the entire solenoide. swap that one with a good known one. I might have one that I can let u borrow to try it. But its been in my closet for a while so im not sure if it is good anymore. If you can get your hands on 1 that is known to be good, that would be the best thing to do. You also might wanna just put a Vtec light on that SOHC since Vtec sometimes is hard to feel or hear on a SOHC. PM me if you need this solenied that I have or if you need help puting the Vtec light on it.
