Fuel Gauge problem
I have a 2004 EB Excursion 4X4 with a 6.0 with 142k miles. My fuel gauge is not working and hasn't in the almost year I've owned the truck. I had the sending unit replaced and all the connections checked from there to the cluster. It used to start and show a reading then it would drop off to empty or even below empty sometimes it would work correctly for a couple days and others by the end of a 30 minute drive it would fall to zero. It now reads empty pretty much all the time. My overhead display also shows 0 miles to empty. I've been just using the trip meter but its getting to the point of real aggravation.

step 1. with a known amount of fuel in tank check the voltage at gauge. the fuel gauge uses a standard 0-5v signal.
if voltage is present at the gauge then you have a faulty gauge.
if no voltage the you have a faulty sender , wire or connector .
if voltage is present at the gauge then you have a faulty gauge.
if no voltage the you have a faulty sender , wire or connector .

Currently at full. So I need to pull the cluster and test the gauge connection with a meter since it’s full I guess it should show 5v?

Put the cluster into self-test mode and 1) check for DTCs and 2) observe the behavior of the gauge during the GAGE sub-test.
No need to pull the cluster initially.

Instrument Cluster Dealer Test Mode
To enter the Instrument Cluster Dealer Test Mode, depress and hold the instrument cluster SELECT/RESET button and then turn the ignition switch to the RUN position. Continue pressing the SELECT/RESET button (five seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within three seconds of the odometer displaying tESt to begin the dealer test mode. Depress the SELECT/RESET button to advance through the following steps until dtc is displayed. Depressing the SELECT/RESET button will display any continuous DTCs stored before proceeding to the next step.
Odometer Display Description
GAGE Activates gauge sweep of all gauges, then displays present gauge values. Also carries out the checksum tests on ROM and EE.
All segments illuminated Illuminates all odometer segments.
bulb Illuminates all micro-controlled lamps and LEDs (low oil pressure/high coolant temperature, low fuel, service engine soon, brake, low range). Install a new bulb or LED as necessary.
r Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline).
EE Displays hexadecimal value for EE level (used when requesting assistance from the hotline).
dt Displays hexadecimal coding of final manufacturing test date (used when requesting assistance from the hotline).
dtc Displays continuous DTCs. Pressing the SELECT/RESET button will display any DTCs stored before proceeding to the next step.
enG Displays the speed in mph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0.
m Displays the speed data (mph) received from the PCM via the SCP network. Displays the metric speed in kph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0.
tAc Displays the tachometer data received from the PCM via the SCP network. Tachometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if engine rpm is 0.
FUEL Displays the actual A/D fuel level. The fuel gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically. If the value displayed is between 0 and 20, the circuit is shorted. Go To Pinpoint Test B.
255=open send +/-0
232=Full stop +/-10
215=Full mark +/-10
178=3/4 mark +/-8
138=1/2 mark +/-7
93=1/4 mark +/-5
41=E mark +/-4
54="LOW FUEL" (0-59)
0-18=short (0-20 max.)
OIL Displays the code (0-255) for the oil pressure switch input to the instrument cluster. Displays the oil pressure reading input to the instrument cluster. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6 psi) will display a value between 000 and 176. A low oil pressure (less than 6 psi) or an inoperative engine oil pressure switch will display a value greater than 176.
dEGC Display of engine temperature in Degrees C input from cylinder head temperature sensor. If the value displayed is -40C, the SCP message for engine temperature has not been received for more than 5 seconds. Go To Pinpoint Test E.
49 C="C" mark
60 C=Normal band start
120 C=Normal band end
119 C=Temperature warning indicator ON
"-40" C=No SCP Message for 5 sec
br Displays the brake fluid level input to the instrument cluster.
bAtt Displays the code (0-255) battery voltage input to the instrument cluster. Battery voltage gauge will indicate present battery voltage.
93-102=6.9-9.1 volts (low voltage)
115-124=8.5-10.7 volts (norm band start)
215-225=15.8-18 volts (norm band end)
230-241=16.9-19.1 volts (high voltage)
rhEo Displays the present hexadecimal value for the instrument cluster backlighting pulse width modulated (PWM) input to the instrument cluster (used when requesting assistance from the hotline).
rhi
rhS
rho PWM input duty cycle.
SCP hexadecimal dimming step (used when requesting assistance from the hotline).
Output driver counts in hexadecimal format (used when requesting assistance from the hotline).
Cr Displays the present RUN/START sense input. Display will show -L with the ignition switch in the START position and -h with the ignition switch in the RUN position.
ALtFa Displays 8-bit hexadecimal value for alternate fuel level. Display will show a value between OO and FF if the message is received.
PA-PE7 Not used.
GAGE Repeats test display cycle.
a Refer to 413-01B (F250 only).
Turn the ignition switch to the OFF position or press and hold the SELECT/RESET button for three or more seconds and release to exit Instrument Cluster Dealer Test Mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

Thank you very much for the procedure I will check this tomorrow and report back. Got busy with work and haven’t had a chance to mess with it. If it tests bad according to the above testing procedure then the fix would be replacement or rebuilding of the cluster I assume?

Many seem to feel that 9352 is one of those codes that is apparently meaningless. However a thorough search of the internet concluded that it is either a low battery code or "key on ignition off" code.
D262 ..........U1262 Missing speed, tacho, engine temp, or odometer count. <- who knows what that means.

Were you able to find out what the root cause was? I've got the same issue on 08 F250 and wonder if the short is in the cluster. I haven't opened the cluster out yet.
