No electricity to fuel pump ... help!!!!

Asked by Dec 26, 2017 at 09:07 PM about the 1986 Ford E-350

Question type: Maintenance & Repair

Hi, please bare with me. I just realized the
description is long. I've been absolutely
immobile and stranded on the godforsaken
property in the woods for about a month
now give or take trying to get thing to run.

Extremely demoralized and have been
stranded on a godforsaken property in the
woods for about a month now. Please
help!!! Not good with electrical systems
I bought a 1985 Ford e350 a month ago
and drove it back to Oregon from
California. Only real problem was the
heater core copping out so I bypassed it.
Ended up to be like a scene from dumb
and dumber with it getting colder and
colder the further up I drove.
Anyways, was driving the truck on the
freeway after coming back and the truck
died as if it were out of gas.
Had to tow it back with money I didn't
have and figured it was a fuel pump gone
i took it out, tested it and sure enough it
was bad.
Put a new one in but no fuel came out of
the hoses. I disconnected the hoses from
the rear tank before AND after the fuel tank
selector valve doing two tests but, there
was still no fuel coming out.
Also please note that it is a dual tank
system. I never used the front tank since
the person I bought it from told me  it
doesn't work and he did not know why.
I had a friend come who bypassed the rear
fuel pump all the way to the fuel selector
switch with a single wire. The truck ran but
there was gas spewing out of the carb. (I
believe this was a wiring issue which I'll
explain later).
I then tried it again the next day and the
truck started and this time there was no
gas coming out of the carb... but it idled for
about 10-15 mins but cut off.
I'm also assuming there might have been
too much gas? Since I told the dude to
connect a fuel return line from the engine
back to the tank, but.....
Anyways, I went on what has evolved to an
extremely demoralizing search for frayed
wires. I found a purple one rubbing up
against the engine that led to the carb and
assume this might have created the carb
circuits to go haywire spewing the gas out
when the dude bypassed the fuel pump. I
reset everything the guy did and put a
jump wire where he spliced the power line
to the fuel pump.
I also used a volt meter and test light to
test the tank selector switch (where the
dude plugged the bypass wire to supply
power to the fuel pump), one of the relays
that leads to the fuel tank selector valve
(located under the hood on the driver side
coming out of the cabs dash gauge. It's
the only relay in between the fuel selector
valve and wires going into the cab. Wonder
which relay this is called?), and the fuel
selector valve. ALL 3 tests had power
going through it at one of the points/wire.
I was going to test the power at the back
where the fuel pump was but something
came up with the dogs and I closed the
hood. After closing the hood, no power
goes to any of the previously tested
The interia switch was also discovered to
be popped up, but couldn't reset since it
wouldn't stay down, so I cut it and
connected the wires.
I also jumped the oil pressure switch for a
troubleshoot and heard a click behind the
dash assuming it was the relay.
I'm trying everything and no Christmas
miracle came. I'm still stuck here with
limited supplies. Even had to mcguyver my
test light. Please help or any suggestions
would be super useful.
I'm guessing with my limited knowledge
that there is something wrong in between
the battery and tank selector switch since
it once did get power, but no longer after I
closed the hood. The only fuse that is
blown is the heater/ac fuse.... as I said,
totally stranded in a cast away type
situation so couldn't find a 30 amp fuse for
it but inserted a 20 amp fuse for shits and
giggles. Do I need to start dismantling the
dash to see what's wrong? Thanks again
and omg, at this point, the guru who can
fix this problem will get so much love. Just
need to get mobile and all appreciation
and thanks will be sent asap!!!
