We have replaced the water pump, thermostat, fan clutch, this is the 3rd radiator, the heater core,and hoses, sending unit for the heat sensor, intake manifold seal, flushed the radiator and still it
overheats, to the point of "puking" . When in the car you can hear the water circulating thru the heater core, if you take the radiator cap off (when cool) and let the car run for a while you can see the antifreeze rotating. Liquid in the canister sometimes even boils. The thermostat on it now is the 2nd one in a week. If you notice the tempurature gauge rising, we can turn on the heat and it lowers the temp on the gauge and keeps it from overflowing. I don't want to blow up or seize the engine, so we drive it very little. We bought the vehicle from the orginial owner, it now has about 182,000 miles on it. We have also replaced transmission, brake booster, ball joints, and several other smaller items. It looks good and runs good and strong, when not overheating.

11 year old wallet grabber truck. Here try this before you completely give up on old paint and put her to pasture. Sounds like air in the cooling system because the thermostat is on the intake manifold take the two bolts out and remove the thermostat drop in a funnel and fill the engine to the top put the thermostat back in turn the heater back on don't start it yet fill to the top of the radiator cap put cap back on. then either drive up a set of ramps jack the front of the truck up as high as you can use two jack stands to hold the truck safety first! remove the cap and idle the engine Air in coolant will cause the water pump to spin air and not pump water. And do one more thing look to see if the cooling fan is pulling air front to back just in case you got the serpentine belt around the water pump the wrong side. If you hear water in the heater it has air in it. Jacked up I hope all the air comes out of the cooling system and you will notice heat at the vents without reving up the engine. The alternative is air entering the cooling system from leaky head gaskets cracked heads.

jon may be right about the air exepr you say you see it curlate in the radaitor so probally not but just in cace i always drill a small 1/8 hole in the flat of the thurmistat if it doesnt all ready have one to eliminate that
to test head gasket over fill the cooling systen when the car is cold start it without the car and look for bubbles comeing out the radiator bubbles is bad it may also be a defective radiator cap swap it with a new ons

Honestly, it sounds like a bad head gasket leaking combustion gases into the cooling system.
You can have the system pressure read at your radiator cap while the engine is running , or they can check for the presence of burned fuel in the coolant.
A radiator shop should be able to do this.

I hate to tell you this, but you have a blown head gasket (most likely) or a cracked head (less likely) or a cracked block (much less likely.) Any of these conditions allow the super-hot combustion gases to be forced into your cooling system, which boils the water.
You need to remove the heads, and have them checked for cracks. Since the engine has so many miles on it, you might as well have a valve job done while the heads are off.

probably not the injectors. could be fuel pump, but if it "seems" like its getting fuel, then I would check the spark plugs first. If them seem okay go with the fuel pump. Try turning the key half way. Not all the way to start just to the radio and stuff. usually if its real quiet you can hear the hummmm of the fuel pump starting up.
