I can pick up a vac gauge and hook it up this weekend.

However, any idea why I can not get any map sensor reading on the datastream?
I have bench tested many ecu's in the past and used a hand operated vac pump on the map sensor and saw it on the datastream.
I am just confused as to why I am not seeing it now.
It is acting like either a broke wire between the sensor and the ecu, or it is not getting power. However I have tested both and they both appear to be good.
