My truck starts mini backfiring and spuddering at 45 mph. I done changed wires, plugs, camshaft sensor, pickup coil, dist cap, catalytic converter, o2 sensors & fuel filter what else could it be.

Start with basics. Fuel pressure spark check.
Was the check engine light on? If it was, what were the codes?

Stop throwing parts at it as you have not corrected the issue with all those parts.

I cant remember what the code was but it was something about camshaft and crankshaft sensor not coordinated together or something like that so replaced both camshaft sensor and pickup coil, someone told me to try replacing fuel pump next. I don't know what to do the diagnostic test don't really show whats wrong, im just wanting to know what to try next.

The gear on the bottom of the distributor is a common failure for this code. The teeth get razor sharp from wear and the pcm cannot get the right sync between the cam and crank sensor.

Also do I really have to have a shop install the distributor because somebody said they have to use a computer to relearn the timing

Could cause backfire but this must be addressed first.

No, the gas gauge is from the sender unit in the tank.

You need to check what I asked first. Lets cross the next bridge after we know this. Stop guessing, you have spent way too much on guesses here with not result. One step at a time.
