1998 SSEI No boost
I have 1998 SSEI and the boost gauge will not go above zero ever, it used to. I replaced the supercharger bypass solenoid and no change have checked for codes no codes were found and the car runs fine. When the car is started I can see the supercharger actuator pull closed and the bypass solenoid is energized and closes also. Could my PCM be confused is there a way to reset it, or would you recomend going to dealer and have it reflashed? Just guessing from what I have read, any help would be apreciated.

Your problem may be the same as mine was. If so here is your answer.
This vacuum line 'T' had popped off the nipple coming out of the lower intake. Only takes about 1 second to fix. Just slip it back on an -WHALLA!!
Good luck.

Problem Solved
Thanks to the guys who helped on this one. The problem turned out to be a sticky arm that the actuator connects too not allowing the boost door to open, a little penetrating oil and away it went lots of boost again before never went above zero. Thanks again.

Just a question... now that you are boosting... what is your gauge going upto on the + side?
The 1/4 mark... 1/2 mark... 3/4 or full?
