yeah I double checked all routing and connections again. all are correct and OK. I t'd into the CCA hose and got 0 vac. I saw a thread that related to that so i'm going back and looking again. if you have any knowledge of that thread please let me know . I have not been able to get any boost since that one time! It's like the rats nest vac. supply is chohed off. The hose between the UIM and firewall with the check valve is not pinched, valve is in the correct direction. I think my next coarse of action is to pull the UIM and check all the solenoids individually. What a pain! I'll research more first though.

Well, to fully test the CCA and the TCA if u wanted to, you should try the key on/key off sequence. The rod CCA and TCA rods should pull in/out when you key on/key off. Im pretty sure its supposed to be able to do this 5 or 6 times and that enough vacuum is stored in teh vacuum chamber.

You can do a few tests back there too.
If you t into the hose on the y-pipe before the CCA, you should have boost reading as the secondary is building and at least 10 after the transition, but that doesn't connect directly to the CCA or the CRV. That hose goes through the UIM and supplies pressure to both the charge control solenoid and the charge relief solenoid.

IF you T into the CRV, there should be vacuum until 4500 rpm and then pressure. If that is not correct, then check the lines around there, and the CRV itself.
Makes sure there was pressure coming from the nipple that I said first. Also, to make sure vacuum is present at the CCA you can put the key to the on positon, yank off the CCA hose, and air should immediatly suck in.

I would seriously try that vacuum leak test I described earlier. P'cola FD told me of this, and it should work wonders. The air will have nowhere to go but out the leak if there is one present.

Quoted from p'cola FD

To test if your CRV is working, first hook a boost gauge to the nipple going to it, and see if it gets vacuum before 4,500 and pressure afterwards. If it is seeing proper signals, then pull it off of the car and apply vacuum to the nipple...it should be open(aka you can blow through it). Now apply pressure to the nipple...it should be closed(aka you can't blow through it). Make sure you are checking the charge relief valve, not the air bypass valve. The CRV gets its vacuum/pressure supply from one of the four nipples lined up on the LIM. The ABV gets its vacuum/pressure supply from the nipple on the top of the UIM.

I hope some of that helps?

yep, i've tried all those tests today. No vac. at the CCA hose. no vac. present at the CRV vac.hose.(CRV tests OK) CCA tests OK, EGR tests OK, ABV tests OK Vac.tank test OK. Although there is no vac. present after i run the engine and go WOT a couple of times. pull the hose off the tank and i don't hear anything. Perform WOT again, Then the keyon/key off procedure. No action on either CCA, or TCA rods. Each tests OK individually. I can hear the thing hissing at me from under the UIM/solenoid area. I've got to go under the UIM tomorrow and check the CR solenoid, and all other solenoids. I'm confident i'll find it soon. I haven't been able to think of anything else for like a week!! I'll let you know the results of the tests tomorrow. I also want to run the vac. source behind the UIM to a different source to try that. I test drove one more time today and the same thing happened. Shift threw third real mellow, maybe 35 mph. push the gas down start to accel and then BAM! 10 psi , pass 4500 and get 5-6. Then no more boost. Oh well. Try again tomorrow!!!WOOO hOOO

oh jeeze, so once u get the primary taken care of, we gotta move onto the secondary... oh jeebus thats gonnabe fun.

yeah but i think i got that narrowed down already. I tolr my customer/neighbor I wanted to replace all the exhaust gaskets while i had the engine out. Didn't want to spend the extra money . well now that it's back in it sounds like Chitty Chitty Bang Bang and the engine to manifold gasget is leaking at the rear side. i'm guessing that is going to keep us from ever reaching full secondary boost. If it aint one thing it's 10 others Ha ha!!!

hows it goin?

Sorry to bring this back all!! just wanted to share the CURE for my problem!! Well, I had all the hoses hooked up right when i put the engine in the car. However i needed to cut and fit a couple of the hoses (1 for the press. tank,{The hose off the rats nest w/o the check valve}, and 1 for the green/black check valve that goes to the UIM) They are rite next to eachother on the nest. I fuct up and put the hose that should go to the press. tank on the check valve to the UIM. And put the hose that should go to the check valve on the press. tank. Did I loose you yet?!!hahahahaha! Anyways, I took the nest off again and was comparing to pics i took of the old hoses, and tada!! there it is. It was staring me in the face all along. P.S. Someone kick me in the nuts for that one!!! I had it correct then fuct it up. YEE hahhh!! Aloha, and welcome back 10-5-5 boost. Now,.. on to the exhaust gasket leaks. Haha..

tell me about it !!!! Thanks a ton though for all your help. As you were the only one that seemed interested in helping solve the problem. I can GARUNTEE that i know where every damn hose goes by memory. I think i'll go sleep for a week or so!! LOL thanks again.
