What's the difference?
Camshaft Position Sensor
Crankshaft Position Sensor
i dont know what the difference is really, i know it only shows a crank position sensor for the truck on auto parts store sites
do you think this is the problem with the truck bucking and dying at operating tempature
i have replaced alot of parts and it still does this
parts i have replaced
Cap
Rotor
IAC
TPS
working on the thermostat right now
any opinions on this, i believe this just might be the source of the problem is there anyway to test it?

RE: What's the difference?
The camshaft position sensor sits on top of your distributor, but under the rotor and cap.It is the flat, round (usually) black plastic piece that the distributor wiring ( not spark plug wires ) hooks to. This sensor sends signals to your PCM so it can control the fuel injection timing. Summit Racing Part Number SMP-LX753.
Thecrankshaft position sensor is mounted at the upper, back, passenger side of the engine behind the passenger side valve cover. It fits into a hole in the bell housing and senses the position of the flex plate. This information is sent to your PCM so the computer can control the engine timing by advancing or retarding the spark as required. It also has an electrical lead to it. Summit Racing shows 3 different sensors available but part number SMP-PC127 has a photo.
If I had to make a guess on your problem without personnally looking at it, I would check the coil. The coil could be old and overheating, thereby not creating the spark you need for the engine to run.
I'd start at the canshaft position sensor and check the wiring for nicks and cuts. Then look at the coil for damage and verify that the wires are connected solidly to the coil and the wiring harness. Make sure your PCM connections are solid. Double check all of your fuel injector electrical connectors and verify that they are correctly engaged. I once had an electrical gremlin that I could not track down, so I disconnected every electrical connection one at a time, checked them for corrosion, and then using dielectric tune up grease on each connector hooked them back up. I don't know which one did it, but my problem was solved.
As timwag2001 mentioned, check your O2 sensors and connections as I had an 89 Pontiac that would die and found a broken O2 sensor wire. Replaced the O2 sensor and she purred like a kitten.
If it isn't an electrical problem then as Socha_62 mentioned, you need to look into the fuel.
Good luck.
