No start got fire gas
82 f150 in line six was driving and ran out of gas filled up now will not start. Got spark got gas compression is 125 to 123 in all cylinders except # 2 which is 113. It acts like it wants to start some times then nothing. Iv tried ether iv even put new plugs in it. Still nothing any ideals going to swap carb tomorrow.
EDIT. got it running the pin on distributor sheared it was moving just enough to allow it to fire every time but off. Thanks for the help

You sure the carb has gas in it?
Filter off looking down carb and move throttle do you see gas squirt?
If motor was cold the choke should be closed. I know you said you gave it a spray what if you pour a little gas down the carb what dose it do?
How much fuel did you put in the tank after you ran out? It may not be enough even if it had less when it ran out.
When were all the rubber fuel lines replaced? If there is a little crack in the rubber between the tank and pump it can be sucking air and not fuel.
With more fuel in the tank up to the point it ran out it would have siphon going on to help the fuel to the pump.
I think I would replace all the rubber fuel line as a start of the right size. I used the wrong size hose and could not get the pump to pull fuel from a gas can sitting on the inner fender even had 2 clamps on the hose at the pump.
The hose is 5/16 inch on my 300 six in a 81 F100

I see fuel spray when I hit throttle filled tank up. It just makes no sense to me. Some times it will try to start then stumble then nothing just crank. Iv poured gas in carb nothing.

I wonder if the spark plugs are getting flooded during the multiple start attempts. If the flooding was bad enough, it may have washed oil from the cylinder walls and lowered compression, too. Does the starter cranking speed seem faster than normal? That's a symptom of reduced compression. Try this:
Remove the plugs and make sure they are clean and dry. Squirt a small spoonful of oil through each spark plug hole. Don't overdo it, only a little bit is needed. With the plugs still removed, engage the starter for a couple of spins to help distribute the oil. Careful, as oil may spray out of the plug holes. Loosely lay a rag over the plug holes to avoid a mess.
Now you can reinstall the plugs and get ready to start. Do NOT touch the gas pedal, though. We don't want any extra gas sprayed in the manifold. Instead, spray about a 3 second burst of starting fluid down the carb neck. Put the can away and hit the starter. With any luck, the engine should respond to the starting fluid. If no joy, do NOT keep spraying more starting fluid. You won't want to blow up anything or lose your eyebrows in the ensuing fireball. The starting fluid is only used for troubleshooting, to see if the ignition system is operating properly.
