Resistance should be between 0.2-0.4 ohms. I hope this helps

check fuel pump , and filter for blockage.

You'll need someone to check the system for trouble codes first.

battery voltage = 12volts or higher standing battery voltage while trying to start = 10volts or higher battery cables tight,clean, no corrosion starter turning engine over check for spark at plugs fuel in tank air able to make it into combustion chamber through air filter fuel arriving at cylinders through fuel injectors when you turn key on, dash lights come on and then go off . well this should get you started diagnosing your no start condition

There is not simple answer to that! (I am assuming that your truck is the EFI model, and not the earlier carbureted version.) You will first need to relieve all pressure from the fuel system by either disconnecting the inertial switch and attempting to start the vehicle, or disconnecting the fuel pump power and attempting to start the vehicle. Once you have depressurized the fuel system, start tracing back from the fuel rail! There will be a pressurized supply side going all the way back to the electric fuel pump, and there will be a low-pressure return line from the other end of the fuel rail returning to the gas tank. You will find that many of the pieces for that vehicle are PRE-FORMED STAINLESS STEEL, and some of those pieces will need to be ordered from Chevy. Best of luck to you!

If you have never done this before get some help from some one that has. It is not a very hard job just time consuming. The main thing is that you keep all the new lines away from a heat source and keep in mind that part of the line is made out of steel. Just follow the same patern of the old lines you should be fine. Just make sure all connections are tight.

Depending on the year, you can one or two of them. Newer models have two. One on each side of the block, located about in the center of the block. Older ones stick out a bit and are about the size of a silver dollar. Newer ones have a bolt that goes thru the center of them with some wires attached. Be careful, the older ones mount into a water jacket. Antifreeze will come out.

Really simple some of them are on the side of the engine block others are on the back of the block

ARE YOU SURE THERE ISNT TWO BULBS ONE FOR TAIL LIGHT AND ONE FOR BREAK LIGHT

Is the code PO560 for your silverado or a kia sportage?

Have you checked the brake switch located on the brake pedal? I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

jack up a wheel and turn the drive shaft if the wheel can be held steady then it is free wheeling repeat the process for the other wheel.

try rebuilding the carb nd or tune up on engine

Under normal driving the fluid never needs to be changed except if it is being serviced for a problem. It should use Dexron VI fluid.

Look for an obstruction in one of the fuel fill lines. Either the liquid line or the vapor fill line, has an obstruction. There may be a kink in one of the lines. There may be something inside that you didn't put there but is there. Look at the filler lines and how they are routed. They should travel downward, to the fuel tank. Has there been any work down recently, in that area?

The Front Axle Actuator is probably your problem. I have replaced my Actuator TWICE in the last 7 years.... The Reason for the Service 4WD was the Failed Attempt. If you are able to test the Power going to the Actuator and there is none, then you have one of 3 switches that went bad but Chevrolet/GM is known for having the Defective Actuators. Aftermarket Actuators are available.

What year is the truck? The first two things to consider checking would be the thermostat and the fan (for the radiator). Would you give more information/details. What tests have you all ready run? What repairs (if any) were performed before this issue. What is the condition of the antifreeze? How does the radiator cap look? What is the temperature of the antifreeze when it overheats? Can you see the antifreeze circulate after the thermostat opens (it could be caused by a faulty water pump, bad propeller)? If i can be of anymore help, let me know. Good luck.

under hood drivers side.

I take it that your engine is a diesel (glo-plugs) in which case the pumping of the accelerator is just good exercise for your leg but does nothing for the engine as it does not have an accelerator pump. faulty glo plugs will only make for hard starting on cold mornings so that will be out also. So the next ting that will give some idea as to the problem will be to have the fault codes read and that will show up the area and sensors that are causing your faults.
