So the FPR solenoid is not needed? Just hook it up like it is on most boinger engines... straight to vac? Well albe... that's pretty simple. heh.

I ask because you know that normally the secondary injectors will not come on until there is a LOAD on the engine and the rpm is over 3500 rpm. They don't come on every time the rpm is over 3500rpm. It's rpm and LOAD. Load as detected by the pressure sensor seeing atmospheric pressure, or MAYBE in your case.......no vacuum at the boost/pressure sensor because the vac hose ain't connected to a vac source or the electrical plug is off. Sorta a long way of saying if there isn't vac there....then the secondary injectors will come on each and every time the rpms are over 3500......wasting gas I suppose. Then again, it could be another thing all together.
As far as the boost sensor checks, just read the dang thing out from the ECU while driving- that'll tell you everything you need to know right there...

The ECU is under the passenger's feet. Lift the carpet, unbolt the metal plate and there it is. You back-probe the ECU plugs with DMM and compare the readings to the data in the FSM.
