SOURCE: fuel gauge stop working
Most likely your problem is the fuel sending unit in the fuel tank mounted with the fuel pump assy. The symptoms might let the gauge sit on or work intermittently then is goes to empty. DON'T let the dealer tell you its only replacable by changing the whole fuel assy.(400.00). This is not true. Look up your vehicle on the AC Delco web site at the top of the page click the link for part look up, it will ask you the year, style, eng size, etc. then you look at fuel , the part is actually called TBI Fuel Meter. If your truck is a 5.7 your part is #17113274 (around $100.00). This is a actual GM part number, some are the AC Delco part number that may have 2 letters and 4 digits, the dealer can cross reference it or order the AC Delco part. This kit comes with a new wiring harness, and instructions. Having said this the other symptom you may have is the gauge goes past full, this is because of a bad ground, most likely around fuel tank. I have replaced approx 6 of these sensors in GM vehicles( 2 of the same year and make as yours) in the last year, its cheap design lets it fail easily.

The dealer near me charges $365 for a 4-cyl, $395 for a 6/8 cyl, or $425 for a 12-cyl. The only actual repair/maintenance you get for that price is an oil change (with Mobil1 and the MB filter, which are CRITICAL, ~$120 on its own) and tire rotation. This makes a lot of people think it's a scam, but really, it's a little steep, but definitely worth doing. The rest of the service consists of a massive inspection of your vehicle covering the following items.
-- Fluid levels
-- Tire tread/pressure/wheel condition
-- Air filter (inc. clean out housing)
-- Cabin air filter (inc. clean out housing)
-- Lubricate sunroof rails, locks, hinges, and seals on body.
-- Drive belt and tensioner
-- HVAC system operation
-- Instruments, cruise control
-- Windows/sunroof operation
-- Transmission fluid
-- Driveshaft, inc. flex discs
-- Road test
-- Reset maintenance light
This is actually pretty essential to do, despite seeming like a lot of money for not much work. I have very rarely done one without catching a few things that the customer needs, and often it was a problem that would have gotten far worse had it been left to its own.

Try this, it is the procedure
for resetting the ASSIST computer on many Mercs
1...Turn Key to position No:2 in the ignition / steering lock and immediately press AND Hold the button "000.0" (the trip reset button) TWICE within the space of 1 (one) second.
2…Turn the key to position No: 0 in the ignition / steering lock. Then release the button.
3...Press AND Hold the button "000.0" (the trip reset button) and turn Key to position No:2 in the ignition / steering lock. Keep button pressed
After about 10 seconds the service indicator will reset and an acoustic signal may briefly sound
That should do it....Good Luck…...Let me know if it works?

I thought they where either on the side of the core support(follow the wire harness and it should go to the relay). If not remove the fuse box lid and then take out the screws retaining the lid housing and you will find a series of relays. There will be one for high speed (engine uses this when temp. is to high) the other is a low speed relay(this is the climate control aux. fan relay) They may have fuses on top of them I know the older models did. I hope I have been helpful.
