Greetings,

My Son has a 1995 Ford F150 with a 5 Liter engine that seems to have a
fuel pump failure sort of problem. It has spark, pressing the 'tire
fitting' on the fuel injector bar on the engine will not spray fuel
when pressed with the ignition switch on. I was talking to him
tonight and was thinking there may be a few more checks that we could
do before we get together to drop the tank. The Trunk isn't at my
house unfortunally. I was wondering if there was a common failure
with these, it has only one fuel tank. He checked the fuse block and
could find no fuse labeled for the fuel pump. I have heard that there
are kill switches for the fuel pump, could this have tripped? if so
where would it be? It sounds from him that the pump isn't getting any
power. Can we feed 12V to it to see if it will pump? The tank isn't
that full, just think that the bolts might be a chore getting loose
not being here at my house.

As always, Thanks in advance,

Markus

fuel pump inertia switch should be located behind R/H kick
panel......disconnect wireing to switch and apply voltage to pink wire.
pump is now powered up. if you cant get fuel to come out your 'tire
thingy' on fuel rail or hear the pump running its time to drop the
tank..........kjun

There's a resettable inertia switch for the fuel pump that will turn it off in
the event of a collision, maybe even a hard bump in the road. not sure where it
is in a truck; in a car, it's driver side rear fender well in the trunk.

did some testing, couldn't get the pump to operate,
Broke down and pulled the tank, sure enough, dead fuel pump...

Thanks again for the help.

Have a most excellent weekend,

Markus
