Nope, car is in base boost mode if you disconnect electrical connector.
In both scenarios I listed it will be in base boost mode?Nope, car is in base boost mode.
My initial problem was my car wouldn't start when it stalled out. Initially it sounded like a crank position sensor. Then it died while driving on the highway showing a P1105 and a P1300. Now the turbo is very loud and doesn't seem to have any boost.That's correct.
It's hard to guess what a generic OBDII adapter shows. My Scangauge will display MAF in g/m and MAP in psi, but I have no way of knowing whether those are actual sensors or calculated values. I assume sensors but I don't know. This is an area where Tech 2 is helpful. It can also show MAF deviation, which tells you the variance of measured and corrected mass air... it's very helpful for diagnosing failures.
If you are actually getting 1psi, that is below base boost. The only way to get that is if the turbo's wastegate or actuator is defective or the engine is running real bad or there is a massive air leak. You can check the first with a Mityvac and a visual inspection. Second doesn't sound like it's the issue. Unhooking the W port will test the third, so would a smoke machine or intake pressure tester, either of which are the far safer options.
P1105 is a lack of boost (charge air pressure). A very serious lack. It should not cause the car to stop running, it would just run very sluggish. The most common reason would be that an intercooler hose blew off. They can look like they are on and actually be blown off the fitting, so you need to get a hand down there and check on the output side.My initial problem was my car wouldn't start when it stalled out.

I wouldn't think a massive boost leak would stop the car from running altogether, maybe I have more than one problem.
I think I'll look at the boost issue now since it's reproducible. I've seen some videos on how to make a a boost leak detector. It looks like I also check the waste gate and end play of the turbo without removing the turbo from the car.
I've had the car a month or so, it ran pretty good for several hundred miles. I got 32 mpg driving it from Virginia to North Carolina. It seemed to have similar power to my wife's 2004 9-3 convertible.
The wastegaye linkage is still there. I tried disconnecting the electrical connector to the bypass valve and got no boost. I tried disconnecting the W vacuum line from the bypass valve and got no boost (do I need to plug the line or cap the hole in the bypass valve when I do this?) . I think I have a big air leak ( although everything LOOKS OK) or a dead turbo.Is the wastegate actuator still attached to the wastegate. That P1105 almost sounds like the code you get when the clip holding the actuator onto the actual wastegate lever falls/rots off allowing the wastegate to get stuck in a fully open position.
I got bypass valve from the WIS. It's the divertor valve Checking the bypass valve (B235R, B205L/R) – 9-3 2000 | SAAB Workshop Information System OnlineYou're saying bypass valve, but I think you mean boost control solenoid, true?
