The MAP sensor will not prevent trigger, but you still need a working MAP sensor for it to run.

Test 2 map sensor 

Link map sensor and factory map sensor 

Neither of those sensors is a Link sensor.  1 is a GM/Delphi sensor, but it could be 1,2,3 or 4Bar as they all look the same.  

The factory 1FZ MAP sensor usually matches the ST185 calibration but if yours is outputting 3.4V it is doesnt sound like it is the normal 1FZ sensor.  You will have to find a MAP sensor with known calibration, it is the most important sensor for engine control so you cant just guess.
