Ran out of gas, now wont start

ok here's the situation a few weeks ago I let my bronco run out of gas now it will not start. I put $15 worth in the tank but I'm thinking maybe there is air in the line. Anyone know what is causing it not to start? or how to get the air off the line. any advice is appreciated.

Thanks,

Mitch

I would say check the fuel press and follow it out from there. prolly like mine was ran low sucked some rust into the sock and couldnt get enough to run on. I took a chance and cleaned it up good put a new sock on ( had one already from another day) and not had any problems since, been months. I cut the access hole to get it out. Have since bought a new pump and waiting till it acts up again to replace it and clean out tank.

yo MITCH,

I assume the starter turns the eng over, but it won't run..

And we also think there are no ignition issues due to any changes.

Check the filter out first; cheap replacement part

Also in your 88 you have the Single-Function Reservoir (SFR)

Overview; "...Dual fuel pump systems must have a fuel accumulator (Single-Function Reservoir

) between them. The Fuel accumulators store fuel from the low-pressure pump for the high-pressure pump. Storing fuel is a great idea for rock crawlers, as the accumulator holds a reserve of fuel, just in case gravity temporarily affects the gas tank. Accumulators also equalize fuel flow between the pumps. If one pump is pushing 72GPH and the other is only flowing 50GPH, something has to give. Once the accumulator is full, excess fuel flows out to the return fuel line, and back to the tank. This keeps the low-pressure pump from stressing the high-pressure pump.

Most SFR's do not have a filter in themSingle-Function Reservoir in 84-89; "...The PN for the filter is given, but you shouldn't actually have a filter in there. It should be an external inline filter further up the frame rail - you only buy the reservoir filter to get the O-ring, and only then if you have some reason to open the reservoir bowl. Unless you're having fuel delivery problems that you've isolated to the reservoir, you should never open it..." Miesk5 NOTE; Steve deleted his post here.

A reservoir marked "DO NOT REMOVE CUP" does not contain a filter. For a replacement O-ring for the cup, buy a NAPA 3268, Fram CG3862, or equivalent filter.

Single-Function Reservoir in 84-89; "...were only used on the early EFIs; carbs & diesels used electrically-operated tank-select valves, and later EFIs use an in-tank fuel delivery module (FDM) that performs these functions. The single-function reservoir (SFR) is used on vehicles with ONE gas tank, like Broncos, vans, & low-trim pickups. The reservoir is always inside the L frame rail beneath the driver's floorpan about 10" behind the frame fuel pump. The 10mm bolt heads are easy to access on the outer face of the frame rail, but some vehicles have a large heat shield that must also be removed...There's not much to the SFR (which is what ALL Broncos of those years have): the '88 version just has the cup & 1 check valve (earlier versions have 2), but it's almost foolproof. Its (meager) function is described in the caption of the 2nd pic..."

I think everything is working right...when i press the relief valve on top of the injectors all i get is air. I heard that was due to air in the line. How can I bleed the lines correctly so i can check? it started perfect before it ran out of gas, I'm just thinking maybe I sucked up some air trying to start it on empty. the fuel filter is pretty new that's why I haven't changed it yet. Thanks for the advice so far guys. Unfortunately I'm selling my truck and I need to get it started up. Its a sad day...

yo..

So, is this correct?..the in-tank pump is running & just air is coming out?

If so, then Elmo got it right-on too!

it could be the pump's pick -up filter (also called the sock) is clogged...or off or kinked...



"...Low-Pressure In-Tank Fuel Pump for '84-89 EFIs

The fuel pump is a motor with an impeller assembly, much like an oil pump, so it will allow fuel to leak backward into the tank when it's not running. This behavior is VITAL to the operation of the dual-function reservoir. Inexpensive aftermarket solenoid-stlye fuel pumps do not allow fuel to leak backward, and so inhibit the DFR"

.. give it a few more tries to see if it clears-up.

Don't run batty down and then jump it to start and let alternator charge batty...

just re-charge batty then try again

I really didn't want to hear that...but what do you do? I tried turning on the switch to let the pump run then pushing the valve at least 50 times as well as letting it turn over then pushing it. But I only got a small amount of gas one time then only air. How hard is it to drop the tank to check that sock? I'm a "shade tree mechanic" and my resources are limited. And why would it hurt to have jumper cables on it while I did it? Thanks for the help you guys always have good info.

yo,

I know you wrote about the filter & I messed-up by not reading what you wrote..; " the fuel filter is pretty new that's why I haven't changed it yet"

Pull the filter first

old way of checking was to pour gas thru it and see if gravity let it thru..

if you need to get to that sock, instead of dropping TANK..

do what our buddy Fred did

on a pal's Bronco here, I used the side panel from an old PC...anything for now;

I used a Dremel and cut-off wheels..think I needed only 2 wheels.

GL!

just wanted to give you guys an update. Just got the truck started, turns out there were holes in my fuel line right before it bends up to the tank. I guess when I ran out of gas it didn't have enough pressure to pull the gas back into the lines. Thanks for all the help guys.

Mitch

yo BK,

Thanks for the info!
