ive searched, tried everything, searched more, tried everything else. my car cuts at a little over 4k and i have no idea whats wrong with it. its the "brick wall effect" as some people put it. its a tii swap, i put a new fuel pump, re-grounded the block, put the knock sensor in, new injectors, set timing, all sorts of stuff, now im running out of ideas and i need some serious help. the car pulls strong up to 4k, but i have no idea whats going on after that.

 

are your secondary fuel injectors working? what do you mean by new injectors?

 

primaries are new, secondaries are not, but i tested them and worked when tested. would the secondaries not working cause such a drastic hesitation like that??

 

Yes.

 

You said you put in a new fuel pump, did you re-wire it as well??

 

the fuel pump came with an additional ground if thats what you mean. i didnt know were to put it, but i checked the resistance from the pump plug to the negative battery and was like .2 or .3 ohms. plus, when i prime the fuel system, it builds pressure like none other(probably from the new pump)
so would the injectors not work for some other reason??? like i said, i tested the injectors when they were out of the car, so....

 

did you plug them back in?

 

the injectors? yeah.

 

Drivers side strut tower, below the trailing coil assembly, there's a white ground tree attached to the strut tower. Remove it, clean the surface where it attaches to the body, thoroughly clean the fitting and re-attach. Regrounding can be helpful, but you need to know which grounds might be causing you to have the 3800 sag. If this doesn't solve the problem, check the voltage of the ECU ground pins at the ECU. All should show 0 volts. If they don't, it will probably help to splice an additional ground to the body from the ECU.

Also, 5th and 6th ports and the actuators should be functional and not sticking. Check them out.

 

cool, ill try cleaning that thing and see what happens. and by the way, its a turbo, so no 5/6th port problem...no 5/6th ports at all!
