3sgte engine in car. now wont start! Options

Yea thats correct. I have a vacuum tube from the turbo to the wastegate, from the wastegate to the large vsv and onward. I looked over the hoses and sprayed carb cleaner on most while at idle. No change in RPM. The most boost Im getting is 5-7 psi. When I pinched off the vacuum hose to the turbo, I got full 14 psi boost to fuel cut. I did this just to make sure I didnt have a problem with the turbo itself. Ive gotta get to the diagrams at work so I can see if everything is hooked up ok. Im thinking I have a problem with a vsv or the wastegate itself. Im working on some links for the pictures of the vacuum tubes. Thanks guys.

Any codes from the ECU?

-Doc

[toyotacrazy]

The only code I have is 34 which is because I hit fuel cut testing the turbo.

[Dr_Tweak]

Where do you have the other vacuum line from the VSV going to?

-Doc

[toyotacrazy]

Its all stock setup. I really didnt mess with it. Ill go look and get right back.

[toyotacrazy]

The vacuum hose goes from the turbo, to the vsv, then from the vsv to this metal pipe that connects to the intake/snorkle tube and to the Idle air control. This metal tube is also where I had a questionable hose that I plugged off so the car would idle. I need to find a diagram. Hope this makes sense.
by the way I dont know how to put these pics on the net, other than using myspace. later

it sounds like you have this all wrong.

from the turbo, go right to the waste gate actuator.
from the waste gate actuator, go to the metal pipe that leads to the tvsv.
thats it.

the hose for your idle should go right to your intake. between the turbos' inlet, and the AFM.


you can upload pics to photobucket. then link to them on here.

Yea, your right. Sorry its been a long day. It goes from the turbo, to the wastegate, to the vsv, then to the metal pipe. My fault. Couldn't I just get a manual boost controller and eleminate the vsv? I would like to figure out whats wrong though. Its probably the way these hoses are routed. All I want is stock boost 10-12

[Dr_Tweak]

Yeah, put the MBC between the turbo and the wastegate actuator and plug the other line.

what kind of exhaust do you have on the car? if its free flowing or an open downpipe, then your probably just seeing a lot of boost creep.

i have a 3in exhaust. i can set it to 10psi and keep it there. but once i got over 4K, i will always creep to at least 14psi.

I plugged those two hoses off so the car would idle. If I didnt it surged and idles at 2,000

[toyotacrazy]

Its a stock exhaust setup. With a convertor below the turbo and a convertor after the flex pipe.

[lagos]

the top vac line normally goes to your charcole canister. most people ditch theirs, so you can just cap that.
the bottom hose, you should disconnect and cap both ends. they normally connect to a round metal valve that is used for the AC idle up system. you can also use the end on the intake manifold for a boost gauge or bov vac line.

i have a crap load of swap pics, if you want to reference something:

Yea I capped the small vac hose on the top. I also capped both the other fittings. It runs strong just only 6-7 psi of boost.

[toyotacrazy]

Ok heres my best guess to why my car wont boost past 7 psi. I noticed the coolant is flowing freely all the time through the radiator. Also my car is running cool by the temp gauge. I think my t-stat is either stuck open or someone took it out completely. IF the ecm has a "safe mode" it may only allow partial boost until the engine reaches normal operating temperature. I dont know for sure. But this is my best guess since the wastegate and related parts seem to work ok.
My second guess is that maybe I have a vacuum leak while under boost. You'd think that the car would idle high or run rough or something. It runs fine.
I'll throw a t-stat in it on Tuesday and let you all know if anything happens. Later

It runs!!!!!!!!!!!!!!!!!!

I got it up and running. The correct ecu did the trick! Just working out the bugs now.....It idles high until I pinch off the large hose on the drivers side of the intake manifold. Then it goes down to normal idle. I think that hose goes to the wastegate. I gotta get a better look at it. At least it runs. Thanks all!!!!!!!!!!!

So the ECU work out good for you im hoping?

Good luck man, i hope to see some numbers from your car soon!

Let me know if you need any other parts.

[Dr_Tweak]

The ECU isn't in safe mode. If it was you'd be getting some codes. Your problem has something to do with the vacuum setup... for simplicity, install the MBC and be done with it.

[toyotacrazy]

Thank you for all the help. Yea...Ill just get a mbc. When I pinched off that vac hose and got full boost. WOW! I cant wait to see that boost all the time. Ill let you guys know when its all working correctly. Thanks again doc. later all.
