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

SOURCE: Ran out of gas and now she won't run!

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.

SOURCE: starts with boost then car dies after 1 km and won't start

once the car is started it runs off the alternator .. so even if your battery is bad the alternator will still run the car .. so it looks lilke your alternator is bad .. when you jumped the car you charged the battery a little but not enough to keep it going since the alternator is not charging . if you hook up a charger overnight then you might be able to run it long enough to get somewhere (garage) .. try to drive when you dont need lights .. those will run down the battery in a short time .. if you have a volt meter then the battery should read about 13.8 to 14.2 volts when the alternator is working properly (car running) .. if it reads lower (like 12volts or less) then the alternator is not charging .. some auto parts stores will test your system free ..

Have a 90 f-250 5.8 gas burner. sat in a warehouse for 2 years. new battery and gas. starts and idles great. run up rpms for 2 minutes and it starts choking out. let off fuel and goes back to idling...


Carburetta is fouled. Run fine on choke - rich mixture. As it warms up and choke pulls off, its starving for gas.
First try adding fuel system cleaner to the gas tank. Do NOT go overboard. No more than double the recommended mix ratio.
The alternative is to remove the carb, open the bowl and spray out the jets and venturi with carb cleaner.

Its possible you may help it by removing the air filter and spraying every orifice you find on top of the carb. With carb cleaner. Be very carefull not to flood, pool carb cleaner in intake as this is not healthy for engine either. You can do this with engine running, so as not to pool, but slowly is best, both in engine speed and volume of carb cleaner.

Very hard to start in the morning.Has new battery, plugs and plugwires and engine turns over good but it takes 8-12 trys before it starts. After it does start if you touch the gas peddle it dies. After it...


Fuel injected? My 87 Porsche and 89 Alpha Romeo have Bosch fuel injection system (the best). They both have a cold start injector driven by the onboard computer. Computers hardly ever fail. But the sensor that tells the computer that the engine is cold can fail or the cold start injector can fail or be dirty. Please go to your autoparts store and get a repair manual, best $ 25 you will ever spend. Good Luck!
