Truck sputtering while going up any grade hill but on level ground runs fine. I've changed coils, wires, plugs, knock sensors, o2 sensors, fuel pump, fuel filters. Any idea why it does this it's driving me crazy not figuring it out. Plz help!

I,m at a stand still. i repaired a 02 silverado for a friend and after 2 days it stopped running while he was driving it. He says it just lost power and shut off. I did plugs ,wires , repaired valve cover gaskets, pcv, oil change . Today2/28/16 i replaced fuel filter-no start, checked coils-all had spark, checked fuel rail-pressure good, took exhaust off thinking back pressure due to plugged cats or muffler-no start, tried starting fluid still nothing. It just cranks with no signs of starting. I got an obd reader and his port doesnt work checked all the fuses and they were good so im stuck . I know cam/crank sensors could be bad , is there a way to check these with an ohm meter as their both 56.$ a piece. im trying to get OBD port to work in the mean time .

What would cause the pwr acc locks not have power to the fuse panel

Are they some fuse that I'm missing

My truck has been giving the intermittent message of "service 4 wheel drive". Not only that but there things happen and some at the same times. The fuel gauge goes crazy or sits on empty. The ABS light comes on; brake light; air bag indicator; gauge lights go on and off; and / or a beeping sound that's stays on a while. These happen while driving and may last up to five minutes. Each time the service 4 wheel drive message usually appears as well. Seems like a short somewhere. Do you have an answer?

a c and heater only comes out the bottom will not come out vents

Driving in 2wd transfer case slips to neutral but 2wd light stays on.(I'm assuming neutral bc the truck quits pulling). If I reverse, it slips out immediately but driving in foreward it may take some time. If I try to lock it in 4 low, it clunks loudly a few times then quits trying. (4 low won't engage.) I brought it to the mechanic who scanned it for codes and there are none. This is a remanned case replicating the exact problems as the old case. I tried an encoder from the mechanics shop but it did the same thing.

It has a rough idle at cold temperatures (below 10°F), I tried replacing the pcv valve and fuel line filter, as well as checked the air intake sensor, and the problem still exists. Any suggestions??

This is the second time changing the blower motor and blower resistor with parts bought from O'Reillys. I am unsure at this point if I need GM parts and if it would solve my problem. Currently in the mornings when starting my truck the fan will not kick in. After driving or letting the truck run for 10 minutes or more the fan will kick in and give me heat. It seems like with the colder temperatures this has become worse. I have replaced the blower motor, blower resistor, check for moisture, and I'm just puzzled.

I have failed inspection because of evap monitor not ready have no light on, had replaced o2 sensor and disconnected battery but completed drive cycle after wards. since repair put on over 300 mile not ready still reads on evap monitor.

it idles normal then slow then back to normal? and when I stop it wants to l like lunge forward? I have to hold the brakes! 5.3 ltr engine v8. my dtc code says faulty knocking sensors? not sure if there is something else wrong before replacing sensors never had this issue before?
