i had a ford fairmont back in the day ( yeah i know bad choice) and i had the same problem and it was all this junk in the gas tank

 

Might sound stupid, but if there was debris in the tank could the weight of the added gasoline help "push" the fuel throught he line and when the tank is nearly empty is doesn't?

 

The sending unit collects the gas from almost the bottom of the tank, and that is where the debris would be no matter how much gas you have in the tank. You may have a fuel pump about to go south on you.

 

but with a full tank the debri will always stay moving and floating but went the gas is almost empty the debri settles

 

look it will cost you nothing to drop the tank and clean it out

 

Not after it has been sitting all night. Whether the tank is full or empty, the debris will all be on the bottom.

 

ok so you have good fuel flow, so more likely weak battery. Mine was doing the same thing last winter here (and our weather doesnt get that cold). It just seems reluctant to fire first thing. Once it had started one time for the day, no problem. It was down on cranking amps even though it was charging properly and showing full voltage. There are new meters around now that dont do that "flatten the battery under load" thing like the old tests. A good sparky will have one.

if it is junk in the tank it will normally affect the car at more than just cold morning start up. A bit of rubbish that gets through the carby wont stop combustion and you say you have a solid stream of fuel per Scott H's test. Debris will normally stop fuel from getting through the carb causing missing (or failure to start) but then may clear itself and seem fine. It would feel the same as running out of gas. Alternatively, it will stick the float valve open and the car may flood...this may be possible in your case, but it wouldnt just do it cold.

Either way, you should have an inline fuel filter and, if in doubt, fit one or replace existing. Takes 10 seconds and will eliminate that possible cause!

good luck

 

to tell you the truth i would get rid of those point i just replaced min not more the 2 weeks ago (because of misfiring) and it fix it! for 2 weeks! so guess I'm putting down the Cash for MSD. !woot!

 

Take the gas line off at the carb and run it into a jar. Have someone try to crank the engine and see what kind of fuel flow you are getting when the tank is down low on fuel. I'll bet it is a weak stream which means you have a fuel pump about to die on you.

 

I'll try this as soon as I get the chance.
