Is it possible to replace wastegate and pre control actuator while on the car?

Yep, no problem at all. Pull the airbox out for room, you have 4 13mm (yes, 13mm) bolts holding the actuators on and 2 C-clips holding the rods to the flapper arms. No biggie.
BTW, you can get those C-clips new from Mazda if yours are shot - I remember them being VERY reasonably priced, so much so that I bought like 5 or 10 of them when I heard the price .

I did it. Still have no first turbo boost. I have transition boost and second turbo but no first.
I have new solenoids (From group buy) and checked the routing of the hoses 20 times.
Will the turbo control actuator prevent me form first boost if it not functioning properly?
Do you think the wastegate door could be broken?

Finally check the CRV (primary turbo BOV) and make sure that's holding boost.
Typically if either of these things aren't working you should hear the boost venting so listen for air escaping.

Ok. So I checked all my check valves. They are new
And are all working.
I also checked my vacume tanks and they both hold
10 psi.
I also check the crv valve. I put 10 psi on small
Nipple and blew into the larger ends. It seems
to be working fine.
Do you think it could be the wastegate? If its not
functioning would I still get second turbo?
I also don't get and boost at idle with wot.
Any other ideas? Thanks for the help

I was searching to try and figure out why I’m not getting boost on my primary turbo and came across my own thread of the same problem from 12 YEARS ago. My car has been is storage for 5-7 years. Time flys by. I have done a tune up and changed all the fluids. Everything is running the same as when I put it in storage except I have to rebuild the brake master cylinder. But I still don’t have any primary boost.
my question is can a bad turbo control solenoid part number N3A1-18-74 cause me to have no primary boost? Or the solenoid that near the vacuum chamber and in front of the right side of the uim cause it? I think that one is the purge control?? All hoses and check valves and the vacuum take were checked today.

9 times out of 10 no primary boost is a big boost leak. It doesn't take much at all - split in the Y-pipe coupler, crack in the hose to the intercooler, etc.
Primary boost isn't going to be affected by any solenoids or any of that mess. Don't concern with that now. Look for a boost leak. Sometimes you can see or feel it just revving the engine in the driveway.
