[QUOTE="RossKean, post: 1447492, member: 19880"] Do we assume measurement is supposed to be in mm? If either mm or in of Hg, it is way off. Pretty close if it is supposed to be a percent of normal atmosphericpressure... I have no idea and no point in me checking my Canadian Gen II. If it is wrong, is it the sensor or the connection back to the ECU? Did you look at the condition of the big connector under the tank? What about the ECU connector? Have a look inside the sensor with a bright light and make sure there isn't a glob of goo there. I wonder what would happen if you tried starting with the sensor disconected electrically...? I think you have to check the other pressure sensor and connections as well and see if someone can get back to you on the pressure units and expected readings for a US Gen I. I would make sure this stuff is right before going further. Did you go through the other diagnostic stuff that can be done? [/QUOTE]
