where to start
sooo i’m an idiot and left my precious 1980 f150 windsor outside uncovered, after seeing what only a year had done, and life just being life i left it for years. now this is what i’m dealing with. It started because i could not get it started, seemed like a fuel pump as it would ignite then die immediately as if fuel wasn’t going through or something. but yeah, this is it https://imgur.com/a/SHs1uiD

Do you have someone that can crank the engine over while you make sure the fuel pump is pumping ? You'll have to pull the fuel feed line off the carb and route it into a can.
I assume you have put a little gas in the carb and tried to start it currently ?

Try that and see what happens. If it tries to go put a little bit in it again. Does it have any fuel in the tank? If you can't get it to go, pull the fuel line off and put the end in a bucket and crank it over to see if fuel comes out. The fuel system is going to be your main problem. The ethanol fuel they sell at the station is bad for getting old and gumming everything up.

there is a very small amount in the tank as of now. was going to add some 91 i have for my audi into it (also going to pour some liqui moly fuel system cleaner or something in with it, as well as some directly into carb to knock some of the **** out of it lol. it’s been years since it’s started i csnt change the oil on it where it is so i’m wondering if oil stabilizer will help... also not very mechanical just learning but do have hanes manual, can try and figure out how to tell if pump is pumping and find the fuel line. thanks guys

As long as the old oil is still in it, I would not worry about that. If you are getting fuel up there, but still can't see any fuel squirting in the carb when you move the throttle by hand, I would crank it over several times with the fuel line hooked up, and then take the plastic handle of a screwdriver and peck on top of the carb. That nasty ethanol fuel is like glue and can make the float needle stick. If you can't get it, you may have to pull the carb off and take it apart to clean it out.

Also realize any fuel in the carb, may not be good for combustion.
So your going to have to:
Verify gas is getting to the carb.
Verify gas is pumping out of the carb bowl once the bowl is full, that can be done by hand, just verify the choke is open and look down the carb as you open the throttle with your hand on the linkage on eh side of the carb. The carb has a accelerator pump in it that gives a shot of fuel as you open the throttle.

Yes,
If you want to be safe when you have disconnected the fuel line from the carb, pull the center wire off the distributor cap. That is the coil wire and will not allow spark. Opp's that's a bad idea...
Do you have any idea what the charge rate is in the battery ? should be at least 12.5 volts. I just want to verify you have enough battery to spin the engine and fuel pump at normal speed.

DO NOT DO THE ABOVE.
You run the risk of having a fire on hand. Pulling the center wire (the high tension lead ) off the dist does NOT stop the coil from sparking. The coil will be sparking and will be looking for path to do so a splash of fuel in the right spot and potentially instant fireball.
Instead, leave the ignition wires alone and pull the horseshoe connector off the coil this will disable the coil. Alternatively, if it is in a miserable spot disconnect the 2 wire (red and white) plug at the Duraspark (ignition module) this disables the whole ignition system.

1. You can do the bucket trick to see if you get any fuel at all. If you don't, you know the fuel pump and fuel tank have a problem.
2. Once you get fuel in the bucket, you can hook the line up back to the carb and see what happens. It's a crap shoot, more than likely the carb is going to need to be rebuilt but you can try it.

so even though the tank was damn near empty and also had a bit of seafoam sitting in it you thinking the tank might be mucked up? i poured about 10 litres of the 91 octane shell vpower (95 ron equivalent i believe) into the tank and that’s what i was pouring into the carb as well as a bit of fuel system cleaner that’s when i got the best result but yeah. if i could get the engine hot sucking somr high pea intake cleaner would maybe help? the bucket thing kind of confuses me as to how they would diagnose anything? sorry i’m so new with mechanics

What do you have as far as fuel line to the carb? Factory was a hard metal line. Usually this stayed metal the whole way, and screws into the carb usually it screws into the fuel filter and then into the carb. Some setups have a very short piece of rubber hose going to the carb.
Whatever you have, take it off. If fuel spills out that is a good sign. Take the line loose, slide the nut out of the way if there is one, and find a long piece of rubber tubing or hose and slide it over the end of the metal fuel line. Stick the other end in a bucket. While you hold onto the end of the line in the bucket, get someone to crank the engine. You should see strong spurts of fuel going into the bucket. If you do, that means your fuel pump is working, and is picking up fuel from the tank.
