SOURCE: replace fuel pump on 03 Ford F350 diesel

simple : obtain replacement pump from parts provider (no used stuff)

Now help me out here: thats the year they were bolted to the pass side front of engine
and not inside the tank right? (better go look to see for sure)

using a tube wrench unscrew the fuel lines (i use large wire nuts to temp block off fuel leakage)

with a 12 mm wrench undo the two side bolts holding the pump to block

wiggle pump it should come straight off

clean mounting place on block with solvent let dry

silicone back (or use gasket that comes with pump ) of pump

apply pump to block (depending on where crank stopped you may have some tension on arm you will have to overcome to get flange to meet block )

use locktite (blue)or simmiliar thread lock on bolts retighten firmly but not hang up the dog tight

use light grease or vasolene on tube connections don't try to tighten dry

Now the fun part your diesel now has air in the fuel system

there are two ways to remove this ( hard and harder)
your choice here are both methods

loosten the fuel supply line for #8 injector ( I did not say remove) 1 full turn ought to be enough

crank engine 30 seconds only
wait 5 minutes for starter to cool down
crank engine 30 sec again
did it start but runs rough while it's still running tighten #8 injector (caution fuel under high pressure)
engine smooth out good your lucky
engine did not start yet
wait 5 minutes
crank engine 30 sec again
start yet
if so tighten #8 injector up

Now here's something I've done to my diesel to make this much less a hasstle

trace fuel line as it comes up from pump
obtain a small low pressure electric fuel pump and a two short pieces of fuel line
and a few clamps

use tube cutter and cut fuel line just before it bends to go in filter
deburr edges
slide tube and clamps over pipe (both sides)
insert pump observe flow arrrow towards filter

the wires of pump can be stretched over to #1 battery terminals

now any time you change a filter or open your fuel system for any reason
all you need do is connect pump to battery
open sharader valve on top of filter for a few min
and start truck as normal
then disconnect wires and stow away for another day

2003 Ford Expedition is hard to start. I takes two to four turns of the key to get the engine to fire.


Could be fuel pressure loss.
The fuel pump is supposed to hold pressure when the engine stops.
If it falls to zero, you would have to cycle the fuel pump relay a few times to get it back up to start.
I would check the fuel pressure first.

Probably the inertia switch for the fuel pump..You owners manual should show you where its located..See if the button has pop up ..If it has push it back down until it clicks..If it wont stay down then hold it down and see if it will start..If it does you will have to replace it..If thats all good then check the relay for the fuel pump..

Your engine is a 5.4. Can you hear the fuel pump when you turn the ignition to "on" ?

Yor problem could be a bad fuel pump or the EEC diode in the main power distribution box.
