The only realistic way the gauges can come back on is if there is a problem with your ignition switch - it is not staying off in the off position. The switch is located at the bottom of the steering column and may have come loose, may be misaligned or may be faulty.

When your stopped, that is usually closed throttle. I'd want to check and clean anything that has to do with idle air system, where applicable. Sometimes with fuel gages, I do testing by using a couple of resistors representing full and empty. If your gage reacts properly, the problem should be the sending unit in the gas tank.

The reason the system "growls" until the light comes on is that when the light is on, the system has determined there is a problem and disabled the system. The "growling" is the pump running. You can get a scanner that is able to access and scan the ABS module. This will give you a place to start.

You need to take it to a qualified repair shop .

Sounds like water in the fuel lines.

There's Water in Your Fuel Line

Besides your vehicle's oil and car battery, the fuel line can also be an issue during winter. In theory, there should be no water in your fuel line from the start. Unfortunately, this is not always the case. When your fuel lines freeze no gasoline can get to the motor, meaning combustion is halted, which leads to your car not turning over. Condensation from temperature fluctuations could leave water in your gas line or fuel tank, which causes further complications. Using fuel with a low alcohol content or premium fuel is one solution. However, in many cases, it may be necessary to repair or replace your fuel lines entirely. You can buy a product that dries up the water in the gas tank when the car is warm from auto parts store. Use a lighter weight oil because your oil gets thicker when below freezing. Try a 5w weight oil.

No it will not work, the Vortec 5.7 is a completely different engine design, either use a 6.0L or a 5.3, they are in the same engine family.

I hate to say this but did you reconnect the electrical connections to the transfer case?

Popping from intake is usually an indication of timing issue. Worst case issue, flat lobe on cam shaft but this is a constant. Check the timing first.

I think you have it spot on with the crankshaft sensor. Before I went and bought another sensor, because they are expensive, try cleaning the old one first. I have a Blazer and that is what I did, but my sensor was bad so I bought another one and everything works now.

with the engine off, grab each pulley that the belt rides on. You are looking for one that is loose. When you find the problem, replace it and install a new belt.

you need to stop both front wheels from turning to see if 4 wd is working just stopping one side means nothing as the diff action is operating and making the opposite wheel go faster

if you have fuel out of the vacuum connection it would have been a problem pressure regulator to check for a bad pump , ave fuel pressure test don( 45-65 psi is the ball park figures for most makes ) have the fault codes read to get to the problem rather than wasting money guessing and not fixing

It could be your differential nut on the input shaft of the front drive has backed off and causing the noise you hear when in 4x4 mode.

To bypass the passlock system you will need to use a multimeter and find the resistance of the chip in the key. Just put one probe lead on each side of the key and measure the resistance. Once you have this reading you will need to chain together resistors to match this reading. Once you have made a resistor you will look at the base of the column for the small orange and white wires in a 2 pin connector. I always snip these on the column side of the connector so if it ever needs to go back to a factory setup there are no cut wires on the vehicle side of the plug to fix. You will snip these wires and install the resistor between them.

replace the ignition switch as there is a problem in the contacts

The best way to do this is change one line at a time or do you have them all off now. I did send you and answer to search for a print on where the lines hook up to. Hope this helps.

Pull the o2 sensor out of the exhaust pipe if possible and see if the truck will start. If it starts and runs at all then you need to check the catalytic converter and muffler as one of them is blocked off inside and it most likely is the cat. When this happens it won't allow fuel to get to the engine cylinders and the truck to start. Hope this helps.
