you would need to drop the tank pull the old pump out and put in a tube to get it to the pickup screen,,instead of the nightmare of putting in a inline pump,,, just put the one in the tank that's factory,,,you can either drop tank or take off the bed of the truck and slide it back

Warm oil will have less viscosity - normal. If you think it is going down too far you can use a higher viscosity oil to start off with. Just make sure that you use the oil that is recommended by the manufacturer and you are good to go. Just use what is called for and fill properly - do not overfill.

What's the fuel pressure ? Hook up a fuel pressure gauge an test it yourself . fuel regulator ??? It's a fuel pressure regulator . I was starting rough and I had a diagnostic done. "They" said it was the fuel regulator. Hard starting - not starting rough . What year is the truck , what engine does it have . If they don't know for sure what's wrong you better try another repair shop that know's how to diagnose . Electrical problems can lead one to believe the fuel pump is bad . Doing voltage drop testing on the electrical circuit is a very good test. Testing Electric Fuel Pump Problems with Voltage Drop Test Plus doing current testing can pin point a bad fuel pump . 059 Engine Hard to Start or No Start Current Test for Fuel Pump

You would have to cut the pump off the pickup tube and add tubing to make up the lost length of the pump. That may be challenging. .

check connection

There would also be a 4WD switch on diff

does it have a cabin air filter? Did you check for a clogged heater core or evaporator core

code for fuel to rich , get the engine tuned up

mains are usually 65-75 foot pounds., rods are usually 40-50 foot pounds.

if it is overheated what smart people do is have a wet and dry compression test done to determine the extent of the damage yes 180.000mils id s fair distance but about 1/2 of what can be expected if the motor was well maintained Not every overheating destroys an engine and what you call severly overheated may just be head gaskets or cracked heads for instance , when the engine was allowed to cool down, coolant added and the engine started , was there any rattles clangs or bangs evident, did it miss badly, immediately blow the water out of the radiator or did it start and run reasonably well What I am trying to do is remove the hysteria of what happened to get to a point where consideration can be given to a reasonable course of action unless you lost all of the coolant from a burst bottom radiator hose there is still coolant around the cylinders even if the pistons have picked up on the cylinder walls (rattles and bangs ) or the rings have softened the damage can be repaired with a cylinder rebore /hone and new pistons and ring sets the heads will need a skim to make them flat again and new head gaskets but generally all of that will return the engine to serviceable condition cheaper than a new engine and be better than a wrecker/junkyard engine a compression test will reveal the extent of the damage to start with , then the head removes will show the rest of the damage to the cylinder bores all you have to do is find an accredited engine reconditioning shop ( not the local mechanic as they will say straight out --new engine) and get a diagnosis and quote before you make the decision

Is it 4X4 ? Drive shaft

GM also offers a built-in trailer-brake controller on 2009 half-ton trucks. Like Ford's, when activated, the truck's ABS brakes reduce gain to the trailer brakes. In GM trucks, however, the controller gain adjustment and hand control are on the left side of the steering column. It's all electronic, not hydraulic, This link has an article you may find interesting Trailer Brake Controllers What Wrong and What Right PickupTrucks com News

The chime system is a class 2 databus. The chime is actually created by the factory radio and plays thru the left front speaker. If the radio is non factory and the appropriate kit was not used ( which has a speaker for the chine) or the front left speaker is blown then you won't have a chime. If you do have a factory radio and the speaker plays the music fine then the problem lies in either the data circuit or the radio. If you have an aftermarket radio and the correct wiring kit was used then either there is a bad connection, blown chime speaker or defective kit.

you can ether disconnect the battery or reset the computer. reseting the computer varies depending on the year and model of your truck. google it or youtube it if disconnecting the battery doesn't work.

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 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 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.
