Ok so heres my problem. I had my motor rebuilt and Vtec worked fine b4 but now I got nothing. I replaced the ecu with a known working one, still no tec. Next i replaced the Vtec pressure switch, again no tec, I then jumped the vtec selinoid to see if it clicked which it did, but still no tec. I checked all the connections for continutityand shorting out to the ecu and its all good but to be sure i wired the vtec selenoid to a switch and tuned it on at around 5000rpm and still nothing. It might be the oil pressure but the oil level is full so i dont know whats wrong. My oil psi gauge at idle is around 20-30ish and at full throttle its around 70-80ish. Just to be sure i took the valve cover off to make sure i put the right cams in there LOL and they were ok. ANy help would be awesome im just about ready to set fire to the car and start on something new.

 

nobody........I dont know much about the internals of the head but what could I look for to be wrong......something the shop might have forgot that would cause vtec not to work?
