I have bought the OE Factory Manuals there for close
to 50 years,but no one seems to want to spend the money

You simply can not work on todays vehicle without the correct
reference material & we don't live in a world of free that provides
much of any use.

Get the wiring diagrams & any diagnostic & emissions manual

You can forget the work shop/service manual,they don't help much

Some whine is not really a problem and is not worth the cost to replace the turbo. You have more than likely heard trucks with turbo whine and they don't worry about it. If the whine is really loud then the turbo has a worn bearing and it will need to be replaced in the near future or it will seize up eventually.

Unspin your fuel filter and see if it has fuel. If you have fuel, then have a look at your Powerbox. Autozone.com may have a free diagram for both the chassis and the Powerboxes. You sign up for free and then scroll to the wiring diagrams. This will help you troubleshoot electrical problems.

Once your engine cools, the "Glowplug" timer should work. When you broke down, the circuit was not active. If this circuit is not active now when the engine is cold, something has happened to the Ignition circuit. This can be the same thing as turning the key off; you have lost the circuit in the keyswitch. Your ignition switch may be bad and shorted while you were driving.

Check also for connections on sensors for the crankshaft and camshaft. The wiring diagrams will allow you to test continuity with an Ohmmeter.
Diesels were simple engines to work with, but the addition of turbo chargers and more electric controls makes anything possible.

I hope my solution helps, please post the root cause when you find it.

Hello: I don't know where you got that code from or what kind of scanner was used or if the operator of the scanner enter the truck information correctly. I think the code is po45 which would indicate the rear O2 sensor is faulty or faulty wiring to the rear O2 sensor. The rear O2 sensor is behind the catalytic converter. I would get the code re-checked again. Auto Zone O'REilly or Advance auto will normally check the code at no cost to you.

CAN YOU FIND IT THE ENGINE AND A/T WIRING DIAGRAM

Hi, try to hook up the hho gas hose into a vacuum line of the crank case (with t-connector) NOT directly b4 the turbo. That might help. Its not getting enough vacuum to "pull" the gas from the cell. How much hho production do you get right now? Greetings, ****
