That will read icp with the free torque app?
Or do I need to buy the real torque app?

Free version will read ICP. Cost is less than a Big Mac so full pro version is easily worth it.

HD Rider invited me to the party under the guise of answering Torque questions. 
This sounds to me like you might get this bad boy running for the price of 8 sets of injector O-rings from Riffraff diesel. No ICP, fuel bleeding everywhere, lots of smoke, hydrolocking - you have an injector really loose or some bad O-rings. Do the Cody test to be sure.
Any foreign fluids in the coolant?
Torque Pro is worth it, if your device connects to the OBDII/BT adaptor.

Sorry I Havnt gotten back to you guys!
I had someone come look at the truck and try to scan it-he said the truck won't communicate with the computer-something electrical is wrong with it.
Tried cranking it and it wouldn't fire-he used ether and it ran for a couple seconds off it and died.
His verdict was its not getting fuel/injectors arnt firing.
I have fuel coming into the fuel bowl up front (can drain the bowl-turn the key on and it refills the bowl)
Again-this is 5ish year old diesel! So I'm sure its lost some potency.
Coolant looks clean.
And I'm in south florida area-port chrlotte.

Check all the fuses. Don't forget the ones under the hood. I believe the diagnostic port is powered from the cig lighter fuse. The WTS light indicates the PCM is getting power.
If all the fuses are good, try swapping the PCM from another truck.

Ill check the fuses. Pretty sure I checked what I think was the cig lighter fuse and it was good but ill double check it/just replace it anyways.
Unfortunately I don't know anyone with another 7.3 to swap parts with
So I'm stuck with having to seriously troubleshoot and replace if I have to.

Not sure what it was called. He has an adapter to a toughbook laptop and tried two different softwares that I guess he uses on 7.3's all he time and it works.
But it wouldn't connect to my truck-which makes sense because my scangauge didn't seem to work with my truck even though it would "connect" it wouldn't read anything but volts.
