Top 10 2003 Ford F350 Super Duty DRW SuperCab Questions & Answers

have put a new fuel regulator on this truck if you done everything else try that

I have recently had this problem with a customer. It seems the 4x4 low will only engage in neutral with the brake applied. And also check fuse. Then select drive and you will feel it lock in. Don't "goose" the fuel when attempting this.

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

DTC P2285 indicates the injector control signal circuit is out of range
so its either the ICP sensor located ontop of the passenger valve cover
or an open or shorted wire between the pcm and icp sensor

The neutral safety switch is located on the drivers side of the transmission where the shifter cable connects to it. Have you tried starting it in neutral?

They will be on the battery side connection,of the starter solenoid switch,on the firewall.

Hello freefallcrus
The fuel pump relay for the 2003 f350, is an integral part of the central junction block(fuse box) located under the left side of the dash. So in order to replace the relay, you would have to replace the junction block. Hope this is helpful.

there is no wastegate on a 6.0l turbo. its a variable geometry turbocharger and doesn't need it. i have never seen a turbocharger cause a misfire, the turbocharger is most likely not your problem. if you didn't clean the intake out when replacing the egr valve there is a really good chance that the egr is bad again. also, a bad egr cooler can cause repeat egr failure. also, fuel injector control module is a common cause for misfire

Does the vehicle has a PATS - anti-theft system ? red light flashing on top of the instrument panel when trying to start ? Fuel pump relay is energized by the PCM - engine computer if no anti-theft system problems . Do you know how to test automotive electrical circuits using a wiring diagram an a DVOM - digital volt ohm meter ?
