2005 gmc 1500 hybrid pickup...Truck lost power to the power steering and all electrical components. Now won't start. Afraid to just replace the hybrid batteries because I don't understand the connection between what the hybrid batteries under the back seat send power to and what the battery under the hood sends power to...How do I know what is recharging the hybrid batteries and if it is faulty. Tried to find a schematic online and manual but was unsuccessful

SOURCE: I have a 2000 GMC

I think you'll find sender & pump are all one assy. What is the reason for changing. If it's the gauge, have you removed, cleaned contacts & re-attached wire plug at pump/sender assy, to see if it would cure your problem? Personally, it's not something I'd want to do twice in a short time, so if I was replacing one (if parts are available to do so) I'd replace the other, unless difference in price was extreme.

SOURCE: online 1996 gmc yukon headlight schematic? free?

It sounds like it's your Headlight switch has gone bad, I'm thinking that the high beams are the daytime running light which is the same as your High beams. 
If you go to Auto Zone or Parts Source, they have the replacement switch with step by step instructions. Try not to run your Headlights too long from your running light's. The headlight's draw more amps then the running lights and can melt the wire which can result in a short and worst a fire.
If you remove the headlight switch from the dash, check the orange wire for power, if there is 12 volts. Good chance's are that the switch is bad, common on the GM's.
Good luck and hope this helps. I believe they go around $70.00 or do what most guys do. Salvage Yard range from $10.00 to $40.00 and there also have warranty.

SOURCE: Auxiliary battery use

The extra battery is there because of the glow plugs and intake heater of the duramax. During cold weather both of these systems draw high amperage from the batteries. A single battery will function, but not as well as a pair.

SOURCE: Power steering lines need to be replaved. How? 90 GMC Sierra 1500

I'm not sure what engine you have in your truck but the chevy's are pretty staight forward in design. Out of the two hoses that you have one is a pressure line and the other is the return. Mostly on the Chevs the pressure is the one that will give you a problem. The one that you can see and is easily accessible is most likely the return line and is a hose on a barbed fitting with a hose clamp. The other is the pressure and as the name suggests the hose clamp will not hold this one so yes it has a fitting that screws into the back of the power steering resevoir. Sometimes you can get to the resevoir from underneath but most likely you will have to remove the power steering pump to get at the hose to reattach the new one. usually not as easy as it sounds as you will have to remove the pulley (press fit) with a power steering pulley remover/installer to access one of the mounting bolts behind it. Hope this helps.

I came back from a 4 day trip and when I started the hybrid, I had no power steering or power brake assist.

Check your power steering fluid level. The power brakes are hydraulic assist and get hydraulic pressure from the power steering pump. If the fluid level is good you may have a bad pump. If the fluid level is low fill it up and find the leak .

I'm getting code 0016 and 0301 on my 2005 gmc sierra pickup, vortec 4.3 v6. Won't start.I've had those codes for several months, but was too busy to get it fixed, with occasional rough starting or poor...

P0016 Crankshaft Position - Camshaft Position Correlation
Replace the Crankshaft position sensor, it's located on the passenger side by the harmonic balance in the front of the engine. Inspect the wire harness and make sure you also buy a can of brake cleaner to clean all the dirt from that area since the sensor is magnetic and will pick up any metallic dirt and will cause faulty reading to your ECM.

P0301 is an indication to a missfire to cylinder #1 which is most likly related to the crankshaft sensor being bad.

Replace the Crank sensor first and it take about 20 min from start to finish. Good luck and keep me posted.

Fuel filter location Sierra

I have been told by a mechanic that the fuel filter is inside the fuel tank. Have to either drop the tank or remove the pickup bed. Access is on the top of the tank. This is poor engineering.
