no torque specs need just put good bead of silicone on back of cover and tighten no need to go overboard just tight.Done hundreds of them when I worked at chevy garage and then 17 years my own shop

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 If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

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.

Really simple some of them are on the side of the engine block others are on the back of the block
