Ran car empty, now won't start (1988 240 wagon)

The 240 wagon sat with an empty gas tank overnight, and after adding 4
gallons to it, it still won't start. I think that there may be an air
bubble in the fuel line or something.

Anyone know how to tackle this?

Thanks in advance,
Andrew

 

I am reminded of C.W. Moss's classic line from 'Bonnie and Clyde' when
he had to deal with a similar problem involving Mr Clyde Barrow's Ford
(I believe it was always Fords that he stole).

'Dirt. Dirt in the fuel line. Just blowed it away'.

Anyway, that's one of the dangers of running dry, especially with an
older car. You can suck up crud from the bottom of the tank and clog the
line.

cheers,

Could be the in-tank fuel pump isn't running. That gem pushes fuel at low
pressure to the main pump, and there are a few possible reasons for it not
working. It may not be getting power because of a bad connection in the fuel
pump relay or the pump may be defective.

Now the devil's choice: your chances of getting fuel coaxed to the main pump
are better if you fill the tank all the way, but if you have to open the
tank and replace the fuel pump you need the tank less than half fuel. The
safe bet is to determine if you have voltage to the pump and if the pump is
running so you'll know if the tank has to be opened. (Access is through the
rear floor, IIRC)

why do you want the tank to be less than half full if you're going to
replace the in-tank pump?... I've done that twice on my '89 240, both times
with the tank a little less than full, and had no problems.

 

Never tried it with the tank full - good to know it isn't a huge problem.

At the bottom of the tank?? Where do you think the fuel intake is anyway?
Putting it at the top of the tank wouldn't exactly work. The crud is why
cars have fuel filters.

 

It's different on a 240 vs 740. On a 240 the sender is mounted in a
horizontal surface at the top of the tank, so as long as the tank isn't
100% full, there's no problem. The 740 (and all 700/900) has the sender
mounted in a surface that is on an angle near the top, narrow part of
the tank. I wouldn't remove this sender unless the fuel level was down
around the half level, although you could probably get away with
anything less than 2/3.

Not exactly sure why, but running an older fuel pump dry can make it
fail where it may have lasted another few years otherwise. My guess is
that you will be replacing the fuel pump. When you pull it let us know
if it works out of the car and the problem was elsewhere, or if it did
indeed die on you.

 

Thanks, Mike - that explains my confusion.

and mine!... didn't realize the 240 and 740 would have different shaped
tanks!

 

I believe that's because the pump uses the gas to keep cool. I've never had
an in-tank pump fail on any car I've owned - perhaps that's because I never
go below 1/4 tank.

Well, I let it sit for a couple days after adding fuel to it, and then it
started right up. It's been running fine for a few days now. Is there anything
that I should keep an eye out for?

 

Low fuel indications? ;-)
