This will set C (chassis) codes. You need to start there as the encoder motor (what performs the electronic shifting for the T-case drive modes {4-hi,2-hi-4lo}) will set codes that will enable you to quickly confirm if the encoder motor is indeed the problem. This is very common given the age of the vehicle.

go to the wreckers and get a replacement fuse holder and wiring harness quicker and easier than trying to replace the fuse holder of the damaged wires

difficult one this ,without doing the tests myself its difficult -? slow cranking is either a iffy battery ,or too small for the current draw ,failing which its the windings on the starter motor ? now if as you say these have been checked then only one thing left and thats to renew or fit another one to double up so to speak and the earth strap from chassis to engine but i would be inclined to fit another cable from battery negative to the engine direct and see what happens ,

What is the exact trouble code you're getting. Which engine?

Timing chain may have skipped a tooth or maybe fuel pump has failed.

Do yourself a favor an take it to a qualified repair shop .

Probably a problem with the abs system, a sensor more than likely.

There are two vent/purge valves - one on the engine that takes vapor from the gas tank and cycles it into the intake manifold. The other one is connected by a hose to the vapor canister. I don't know which one you bought, but it can't hurt to replace both - the one that fails most often is the one connected to the canister and is usually mounted under the vehicle at the back. It often fails due to road contamination getting into the solenoid.

if you have a limited slip differential or a diff locker in action , that is what will happen if the unit is locked up if you do not have anything but a normal diff, it indicates gear failure and the side gears ( spider gears ) have metal in the teeth and are jammed

check/ replace the light control module

Brake light switch under the dash on brake pedal arm

Are there any lights on? Sometimes if the parking brake is applied it will ring as a warning.

hi have a look here Chevrolet Workshop Manuals

This may be an issue that’s easily solved but requires a diagnostic scanner that’s more advanced than most cheaper models like found at homes or most auto parts store chains. Ask friends/family who the most knowledgeable/reasonable mechanic that they know is- preferably one with training and dealership/high end shop experience- they’ll be more likely to have the better diagnostic equipment. If I took the context of the question wrong and you mean the time it takes for the evaporation system to cycle- that varies by vehicle but usually isn’t a long time- call your local dealer depending on the manufacturer of the vehicle and ask them- ask for the parts department, also try service if they don’t help. Many will allow you to ask a technician a question if you ask the right way...good luck
