Silverado :: 2001 5.3L 4WD - Erratic Fuel Gauge
Oct 23, 2012
I have a 2001 Silverado 5.3L 4WD. About 40k miles ago the fuel pump decided it didn't want to work anymore, so it got replaced. Now, my fuel gauge is out of its mind. I have read that it could be a sending unit, or it could be an issue with the gauges. I checked the invoice, I got an Airtex fuel pump, which is apparently not as desirable sadly. Is there a way to check where the problem might be? Is there a way to somehow diagnose if it is the sending unit or the gauge cluster without spending a couple hundred bucks at a shop?

I'm having an issue on my 2002 F350 7.3. Today I hop in it and drive off I notice my speedometer stopped working. My overdrive light on the shifter started flashing. The trans seems like its not shifting correctly. It will eventually shift into overdrive but not always. Also now when I start off my fuel gauge raises and when I come to a stop it drops all the way to E and causes the ding and fuel light to light up. I figured this was all due to the VSS being bad. So I drove over to Autozone bought another VSS and a cheap tool set and changed it in the parking lot. No dice. I do have a scanner to pull the trans code but its late and I just got home.

I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

My dads 05 f250 6.0 PSD. He says he'll take off in the morning and the fuel gauge will randomly drop to empty and trigger the low fuel light, but then also the Check Engine Light will come on. My brother did a code scan and no codes come up. Where we should be looking to remedy this one?

I have a 2000 Silverado Z71 with the fuel gauge swinging from empty to full and all in between. I have heard of others doing this. I guess maybe its time for a new fuel module. It's been doing this for a couple of years, just keep putting it off. Is it easier to move the bed back or drop the gas tank? Also I have developed hard starting problems here lately, It having too crank extra long before it starts up. Could this be a sign the fuel pump is getting ready to go out.

New battery installed a few weeks ago - 120k on 2001 Silverado. When it is rainy out, the gauge acts erratically (yesterday the needle was between 14 and 19, today it is between 9 and 14 and the battery light is on. What can I check to figure out what might be happening?

Having 55k on my 2007 Santa Fe, and having brought it in 1 month ago for that 46k check up, this is my problem since. It started with an erratic gas gauge last Friday ,my tank said empty knowing i still had 1/4 tank, so l filled it up, 30 minutes later light goes on seems no gas in it, 30 seconds later check engine goes on, the Fe is running fine though, I called the dealer and made an appointment for next week, he said as long as car runs fine I can drive it.
Engine light goes off when fuel indicates 3/4 full, but erratic gas gauge seems to fluctuate.

On my 2002 Santa Fe, the gas gauge moves slowly after filling up. It takes about a minute or two for the gauge to reach full. I'm not sure if this is normal or not but the more troubleshooting I do I'm starting to think it is. Need to confirm this?
Also, the low fuel indicator never comes on. I disconnected the connector from the fuel pump and jumpered pin 1 to pin 5 and the light did come on (after turning the key on). I replaced the sending unit (driver side only) but the light still doesn't come on. The only other thing I could think of was dirty contacts so I cleaned them really good. Still no light. What else I can try?

I replaced my battery. Once I connected my new battery, my fuel and temperature gauge started working strangely. They would either be high, then go low, then go back high. My interior lights, clock, and radio stopped working. Could it be a relay? I checked all the fuses with a test light and they all looked good.

I have a 2001 prius. It has around 105k miles on it. i bought it when it had 86k. I've had 0 issues with the car other than replacing the 12v battery in the trunk and its always run like a champ. Today though, i went to start the car and it started up as normal. I left the keys in the car for a second to get out and talk to my wife.
When i happened to look in through the window though i saw that the cars fuel gauge was all of a sudden flashing. The entire bar. (when i started it originally it had 5 bars of fuel) I got back in the car to investigate and noticed that the engine had turned off. All the power was still on with no triangle of death/turtle or anything else. only the flashing fuel gauge was on. I tried restarting it multiple times to no avail. The power will come on fine, and the dash will appear as normal. The motor just will not start.
I thought it might be fuel so i went and added a gallon just in case, but still no luck. Problem usually have lights that come on or the triangle of death.

I've got an 01 that I recently bought with bad batteries. I replaced the 12V and the hv batteries, and all the codes cleared out. The gas gauge was flashing 1 bar and I got the message to add fuel. I first put 1 gallon in thinking at least the gauge should stop blinking. When it didn't, I added 2 more gallons. Still no change. After pulling the rear seat to look for the sending unit, we dropped the tank only to find that it's not replaceable!

My 01 sl2 wont start and the gauge says that the car is empty (before this problem, everything was working fine). I know that I have more than a half tank of gas, the car continuously turns over but wont start. I replaced the fuel pump and still it wont start (not to mention that the tank was more than half full at the time). I checked all the fuses and relays and everything seems fine. I am not even getting gas pumped to the filter.

I just bought a 01 Intrigue that the dash lights don't work and the gas gauge stays at fuel when you start the car. It goes to empty when you shut it off.

So right now I'm not able to start my Toyota's engine. I checked multiple screens and found several weird symptoms that I never saw before.
1. When attempting to turn the engine on, the square light that appear over the selected D, N, P positions etc does not appear at all and the 'Ready' light never appears. When putting the car into the Parked mode the square does not appear over the 'P' on the dashboard or any of the other modes and Ready light does not display.
2 . On the dashboard the fuel gauge is blinking continuously. Its showing full bars while blinking even though I have about 3 cars worth of gas in the car.
3. On the computer screen when I go to the Energy menu (The screen that shows the Battery life and the Motor and Engine working together) The battery life is showing as completely empty. But the battery should be working considering the computer screen even turns on. Radio also works.
4. The OBD II scanner does not get a reading. The scanner powers on when plugged into the car, but a "Linking Error" occurs when attempting to read any error codes.
5. On the same computer screen where the Energy menu is displayed, the Temperature gauge is showing an "E" instead of an actual temperature.
6. On the outside of the car I hear a very faint sound that I don't recognize. It could be nothing but its not a sound I ever heard before.
Also NO WARNING LIGHTS are appearing on the dashboard. Which makes sense considering the car engine is not turned on to show anything. I don't know where this issue is coming from?

Just bought my 5th Vdub an 01 Jetta Wolfsburg with 1.8T and 5 speed manual. I bought it from a local dealer and found the speedo not working. they ordered parts for it to fix that and the front end. They tried to fix it by replacing the VSS. CEL was off when I first started driving it then came on shortly and began to stutter. I haven't hooked my vag-com yet because I just got home with it a little while ago. I think it may be a loose wire because it also beeps and fuel gauge goes to empty around corners. Typical areas to look for etc???

I have a 2001 F150 Supercrew (5.4 V8, 2WD,Auto trans) and recently when we fill the gas tank, the fuel tank doesn't go all the way up to the "full" line. Don't know if this matters but: about a year 1/2 ago in a little town (while on vacation), we broke down and the trouble was the fuel pump. The little town did have a small auto-parts store, and luckily had the fuel pump we needed. Unfortunately we didn't have much as far as tools and we wound up tearing/cutting the filler hose and the vent line.
The little auto store did not have the correct rubber filler & vent hoses for my truck and would take a few days get in stock. We changed out the entire fuel pump and sender unit, and were able to modify some rubber hoses for a new filler & vent line hose. Everything worked great for a year 1/2 but in the last few weeks we have noticed that when we fill the tank, the gas gauge does not go all the way up to the "F" line to show full. With the price of gas, it is important to know exactly how much is really in the tank. Also, is there a battery in the ceiling console for the temperature and compass? Ours just stopped working yesterday.

My 2012 Sonata has the erratic fuel level indication. I've read enough posts here to pretty much assume I need to replace the sending unit.
I could go with OEM, but it seems this has plagued Hyundais for many years and across many models.
While I have the (fuel pump, filter & sender) assembly out (of the tank), when (miles) is it recommended to replace the fuel filter?

Ok so the fuel gauge says empty and the low fuel light stays on even though the tank is full. I'm assuming its either the gauges or the sending unit. If it is the sending unit where is it located on this car?

I have a 2002 Prius with about 150,000 miles on it. A couple weeks ago, I noticed that the parking brake light on my instrument cluster didn't light up when I engaged it. Soon, all 10 bars on the fuel gauge started blinking. The seat belt reminder, open door warning, and headlight indicator lights aren't working, either. Any clues as to what could be causing all these malfunctions, or have I had more than one problem develop in close succession?

97 shortie. 3.0 245,000 miles. I've already cleaned the throttle body and the idle air control valve. Throttle position sensor reads 5 volts, good ground, and a smooth voltage increase from idle to wide open throttle and back down. Which of these codes is most likely to cause erratic idle? Mostly in the morning.
P0340 Camshaft position sensor.
P1443 Evaporative purge flow sensor.
P0401 Insufficient EGR flow.
P0171 Air/fuel ratio is too lean or rich for PCM to correct.
I doubt it's number 1, and number 4 seems too general to be any use. I'm leaning toward number 3. Seems I read somewhere that the tube from the exhaust gets plugged up. This started when I disconnected a plug from the blue air bag box to get rid of that beeping. Coincidence?

I have a 2001 Elantra GLS. The tranny shifts smooth. At around 40mph, it wants to shift into what I guess is overdrive. At that speed it is like it can't figure out where it wants to be and will down and upshift. Aside from that the tranny has no other problems.
