Comments on: Do older cars, In particular a 84 Ford LTD need to be hooked up to the alternator for the fuel to pump? http://www.cookfordinc.com/ford-cars/do-older-cars-in-particular-a-84-ford-ltd-need-to-be-hooked-up-to-the-alternator-for-the-fuel-to-pump Covering everything related to Ford, Chevy, cars and more Wed, 08 Feb 2012 12:13:47 +0000 http://wordpress.org/?v=2.7 hourly 1 By: some guy http://www.cookfordinc.com/ford-cars/do-older-cars-in-particular-a-84-ford-ltd-need-to-be-hooked-up-to-the-alternator-for-the-fuel-to-pump/comment-page-1#comment-1553 some guy Sat, 04 Jul 2009 16:16:59 +0000 http://www.cookfordinc.com/ford-cars/do-older-cars-in-particular-a-84-ford-ltd-need-to-be-hooked-up-to-the-alternator-for-the-fuel-to-pump#comment-1553 The answer is no. That probably still has a mechanical fuel pump so as long as the engine is turning over you should get fuel to the carb. And as you say you have fuel to the carb but it is not spraying I would suspect you may have a bad accelerator pump inside the carb. or a bad needle and seat assembly that will not allow fuel into the carb. If the car has been sitting for a while the accelerator pump could have dried out and won't pump anymore. That's where I would look first.<br><b>References : </b><br> The answer is no.

What it probably wont do is give a spark unless the whole circuit is connected and the battery is FULLY charged. By now, the plugs are prolly fouled from unburnt gas. I would look at a couple of plugs, wire up the alternator and get a fully charged battery AND get a jump.<br><b>References : </b><br> No, it’ll pump up anyway; it’s mechanical.

So, you could have a stuck float, the fuel filter may be clogged up, if it's an electronic carb, the little rotary pump inside may be jammed or not working. If you dribble gas down into the top of the carb, does the car try to fire then? If so, check the fuel supply by unhooking the line from the carb, and running a rubber hose from the end of the line to a small jar or gas container, and see if the fuel pump IS pumping any gas. If so, then it may be the carb's internal float or filter. Good luck!
