Fuel pump changed and new symptom shows up ~~!
Ok, Fuel pump has changed. Thanks to Scott @ Mazsport 
crank crank crank crank crank .... for maybe 10 seconds, finally fuel pulled up and engine started ~~~
well well well ~~~~~~
I had this P0661 problem for a while and I didnt really cared about but.
Now everytime I WOT , there is a "MAJOR" choke around 3750~ rpm.
I think* thats when the secondary injector turns on, right ?
Hmm, is it possible that when I was replacing my fuel pump, something went into the fuel line and when I "crank it" the "Stuff" gone to the secondary fuel injector ?
Or maybe there is something wrong with the connection on the fuel pump ? there is a fuel line I think they use it to drain fuel from the other side of the tank, if thats not "secure" will crap like this happen ?
ideas ? anyone ?
(Oh btw, after the choke @ 3750, the rpm goes up smooth till 9K, so I dunno)

Scott just lend me the tool to open the cap, I installed another "new" OEM pump.
how did I run the vacuum line ?? hmm u're talking about the tube that goes into the middle of the pump right ? ... I think I did it the way "stock" did it, and Im fairly sure that I secure the stupid "quick connect connector"

Ok, got my AFR map.
The red circle means I shift from 1st to 2nd.
Then I pull the rest in the 2nd gear.
Plus, my CEL picture.
damn, when I first start my car b4, my LTFT is like 17% !!!! now its going down. like around 8, STFT is like -0.2% -_-
Notice, when I said I had "Chokes" at around 3750 rpm, I had about 1/2 tank left in my tank, after I made the post, I went to BP and Fill it all up. Choke at 3750 is gone but the choke now happening randomly, EVEN when I was doing the AFR picture pull. (but it chokes above 4.5K rpm randomly, if that helps)
hmm ... suck

when I first start the car up, the car feels like completely lack of power. but maybe my butt dyno "adjusted itself" couple minutes later hmm ....
Maybe I will just take the pump out again when the fuel is low. next monday I suppose.
Gonna send Scott's tool back to him tomorrow(UPS cut off time was 5, didnt make it today)
this time Im gonna find myself another tool hmm. I guess I'll ask swoope
*oh hey MM, do I need to get myself another pump gasket? this gasket aint cheap ! I put a new one in today, no leak so far. but if I have to get another one ... *sigh*

Blah ! maybe I did, but I was really careful when I install it and made sure that the arrow is pointing forward the whole time hmm .... maybe the bottom part was twisted already ? I dunno ~

I just borrowed the tool from my mazda dealership. They made me pay a hefty deposit but I got it back when I returned it. Have you asked them?
Also, the P0661 is a SSV CEL. Have you checked the vacuum lines on the vacuum chamber under the UIM? Have you checked the vacuum line going to the SSV actuator? Have you checked the SSV actuator? Have you checked the connector for the SSV solenoid valve?
You may not be having a problem with fuel. You could be having a problem with air.

I borrowed the tool from my dealer when I swapped my pump as well.
Actually, I borrowed the tech, too.
I just rolled over and gave my buddy Karl a few bucks to go out in the lot and rip the ring off and put the pump in.
I gave up on trying to beat that ring off the pump after two days and several broken teeth.
I even made a crazy tool with clamps and bolts and welded iron stock.
Even with the Mazda SST, it took a LOT of effort to get the ring off. Karl took a pretty good shot of gasoline right in the eye during the procedure.

When your WOT does it almost feel that it's gettign too much fuel and not burning the gas fast enough? or is it like there is no fuel at all....depends on how it sounds i guess I would def check out the make sure it's install the right way with no twisting involved haha

blah, the ring was a bitch to get off. but I managed to get it off without breaking anything, the tool from Scott was a big help
I just installed the Ron Davis Rad, MS CAI, and god damn It I forgot to get more coolant cuz I drain the engine block and now Im short on coolant !
gonna go out and buy some, then gonna test the car out, will be back in a few hours.

Back from testing.
Still hesitating. above 4K rpm.
Temp wise, I will say the Ron Davis/Re-Medy/Paul's Radiator lower the temp much much faster than Koyo. but its still spike like when I had the Koyo Rad. Highest I've seen is 107 Celsius. and its just 88 outside.
As "always" temp climbs up fast if I push the car hard.
Maybe I should go back to the basics, cheap the piece one by one. Till I find out the cause (hope its not the engine seals leaking, but it runs fine so maybe not)

trying to figure how to get it to lower the temp.
its not fan related, at least I already replaced motor #2 myself.
its not rad related
Now Im going to do it step by step, Thermostat tomorrow. Cuz it seems like if I push the car hard, the water flows slow so that temperature builds up in the engine, result is even higher temp. problems will go away as soon as I let my right foot off the throttle. :|

1. Could be, I will try to bleed it again
2. I replaced motor #2. maybe I should get a voltmeter to test #1 as well
3. I never have Mazsport cooling mod.
Im going out to buy tons of coolant, distilled, and coolant system flush stuff right now, Will replace the thermostat, flush, refill, drain, and refill with coolant today.
will see what happens later. wish me luck ~
