Looking forward to see what people say about your situation. I too have a 4runner with a 3.0 V6 that indicates little to no pressure at any time except when I start it cold. I think it does occasionally jump up to a normal reading for no apparent reason when warmed up, but it shows a normal reading much more often when it's cold. Even that is erratic though (I think). -- Matt
