Keep your gas fresh

adding lots of dry gas can be part of problem the gas if old and just sitting in tank/lines/carb will cause problems check and clean the fuel system

The damage is already done. Gasoline breaks down within 1 year. Drain and flush the old fuel out of the gas tank(s). Try adding Chevron Techron fuel injection cleaner to the replacement gas. That may work. However, you probably need to remove all the fuel injectors [if it's a fuel injected engine] and have them sent out to be professionally [ultrasonic] cleaned and tested. Fords are notorious for fuel injector problems. Also do a fuel system pressure test, as the bad gas may have damaged the electric fuel pump [located in the fuel tank(s). For a carbureted engine, you will need to have the carburetor overhauled or replaced with a rebuilt unit. NEVER let a vehicle sit unused for more than 6 months without first treating the gasoline. I always add a fuel stabilization product like Sta-Bil to the fuel, if the engine will not be run for at least 2 months or more. Adding these products after the fuel has gone bad [is already old] will not help. Then it's to late. Below is a link for Sta-Bil. I've used this product for over 20 years. It will save a LOT of grief, when storing vehicles or gas powered lawn equipment. See

How much gas did you add to the vehicle? Is it showing up on the gas gauge? It is possible that you did not add enough gas to the tank and the fuel pump is not sending enough gas to the engine. It is also possible that since the car was sitting for 6 months water or moisture could have accumulated inside the gas tank or gas lines and preventing the gas from getting to the engine. You can try adding a bottle of dry gas into the gas tank that will dry out any water or moisture in the gas tank and add some more gas. You can but a bottle of dry gas from any auto parts store fairly cheap. Also you can have someone open the hood of the vehicle and put a little bit of gas or starting fluid into the throttle body and then try starting the vehicle. If it starts for a few seconds but won't stay running you may have a bad fuel pump or clogged gas filter which would need to be checked out by a mechanic. Good luck.

My wife once mistakenly topped off the tank with diesel instead of gas. Same symptoms. Gas also goes bad when it sits in a tank for several months without a stabilizer. Try adding a fuel stabilizer and filling the tank with high-octane premium gas.

Gas that sits too long won't fire easily that's why we have to add winterize to our lawn mowers!
Try filling the tank with some high grade fuel cleaner additive. This stuff is like rocket fuel (about $10).
Also add a can of dry gas as you may have a lot of water and water vapor in your system!
Get a couple more cans of starter fluid too. (I always needed at least two to get my diesel running for summer)
Keep spraying and starting (It always took me at least a full can sometimes 2)
When it starts keep the gas pedal down and rev high for a good 5-10 minutes then see if it will idle.
If it still stumbles and falls consider adding another can of fuel system cleaner and/or dry gas.
Don't drain the tank as this usually just makes it worse by letting the bottom sludge stir up.
Never let your gas tank get too low as this will foul up your fuel system and always add fuel cleaner after every oil change (a must for fuel injection and cat. converter care)

Good Luck!
