I suggest you take it to a ASE certified repair shop , it sounds like you know nothing about automotive electrical systems . I don't know who told you that a hot wire is touching ! I'd say they don't have a clue either ! From my 30years experience , I'd say the instrument cluster is bad , because I know GM had a lot of problems with them ! But if you still think you want to mess with it , you'll need to pull the instrument cluster out of the vehicle , find a wiring diagram an check the instrument cluster wiring harness an connector for bare wires an check for power an grounds with a DVOM - digital volt ohm meter !
  1. Turn ON the ignition, with the engine OFF.
  2. Observe the IPC.
Does the instrument cluster operate normally?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3


  1. Turn OFF the ignition.
  2. Disconnect the IPC.
  3. Turn ON the ignition, with the engine OFF.
  4. Connect a test lamp between the ignition 1 voltage circuit and a good ground.
Does the test lamp illuminate?
Go to Step 4
Go to Step 7
Connect a test lamp between the ignition 1 voltage circuit of the IPC and the ground circuit of the IPC.
Does the test lamp illuminate? yes or no
Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition? yes or no
Repair the open or a high resistance in the ground circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you complete the repair? yes or no
Replace the IPC. Refer to Instrument Cluster Replacement .
Did you complete the replacement?

I am told the glow plugs heat up in "firing" order, also the Duramax uses a intake air heater to warm the air on cold starts.

the horn is more than likely a relay or fuse. But the air bag should be checked by a pro, these can be deadly!, it could be a sensor. the air bag will not work when the light is on

Turbochargers do not disengage. They are powered directly from the engine exhaust stream. At idle the turbocharger will have little energy as there is little exhaust. It will just spin slowly (internally) thus providing virtually no boost.

Resistance should be between 0.2-0.4 ohms. I hope this helps

check fuel pump , and filter for blockage.

You'll need someone to check the system for trouble codes first.

battery voltage = 12volts or higher standing
battery voltage while trying to start = 10volts or higher
battery cables tight,clean, no corrosion
starter turning engine over
check for spark at plugs
fuel in tank
air able to make it into combustion chamber through air filter
fuel arriving at cylinders through fuel injectors
when you turn key on, dash lights come on and then go off .
well this should get you started diagnosing your no start condition

There is not simple answer to that! (I am assuming that your truck is the EFI model, and not the earlier carbureted version.) You will first need to relieve all pressure from the fuel system by either disconnecting the inertial switch and attempting to start the vehicle, or disconnecting the fuel pump power and attempting to start the vehicle. Once you have depressurized the fuel system, start tracing back from the fuel rail! There will be a pressurized supply side going all the way back to the electric fuel pump, and there will be a low-pressure return line from the other end of the fuel rail returning to the gas tank.
You will find that many of the pieces for that vehicle are PRE-FORMED STAINLESS STEEL, and some of those pieces will need to be ordered from Chevy. Best of luck to you!

If you have never done this before get some help from some one that has. It is not a very hard job just time consuming. The main thing is that you keep all the new lines away from a heat source and keep in mind that part of the line is made out of steel. Just follow the same patern of the old lines you should be fine. Just make sure all connections are tight.

Depending on the year, you can one or two of them. Newer models have two. One on each side of the block, located about in the center of the block. Older ones stick out a bit and are about the size of a silver dollar. Newer ones have a bolt that goes thru the center of them with some wires attached. Be careful, the older ones mount into a water jacket. Antifreeze will come out.
