no boost or power need some guidance

So to start off bought the truck non running.
Former owner said he had a new turbo put on recently.
Then the other day it lost all power and died on him and would not start or crank.

So that is when i bought it.
After alot of trouble shooting I had to replace
pcm to make start.
ficm to make run better.
icp was leaking.replaced it
y-pipe was leaking. replaced it

Now that it is running it has no power. Turbo is not spooling up.
i pressure tested cac system and has no leaks.

what do i need to check or test??? Kinda new to the turbo stuff.

Re: no boost or power need some guidance

I am surprised at the bad PCM, that isn't common.

What year model is it and where is the ICP sensor located? What turbo was installed?

You need a way to retrieve engine data when running. The cheapest route is a smart phone app (ForScan or Torque Pro). With these you also need an ELM327 adapter (bluetooth for Android and WiFi for ios).

You could also get a ScangaugeII.

There are others, but they can get expensive.

Once you get that equipment, you need to post some key-on/engine-off data:
Baro (barometer sensor)
MAP
EBP (Exhaust Back Pressure sensor)

Then please post the MAP and EBP readings at cold idle, hot idle, cruising at 55 mph, and at WOT.

Re: no boost or power need some guidance

Need MAP not MAF

Your 03 will most likely not use the EBP sensor, so no need to report that.
