On that particular model if my memory serves me well, the harness for the fuel pump and sending unit, goes in at back of tank, right where it's pretty good at collecting dirt etc all around it. I would take the time to get under there and clean area around sending unit/fuel pump. Once that's cleaned off as best you can, remove wiring plug & clean & inspect the contacts in it, as well as on tank unit with electrical cleaner, then add some di-electric grease to contacts before putting it back together. Also, follow harness back from tank a little way, as there might be another connection in that area, that you can pull apart & try the same. All that will cost is about $5-$10 in spray & lube, and a llittle of your time.

I am assuming that you have checked all the wires going to the fuel gauge under the dash. Next check the wires on top of the fuel tank, make sure that the ground wire is secure, you may have to drop the tank to do this, but if the wires are ok the fuel sending unit is bad. Its inside the tank and accessable by removing the screws holding it to the top of the tank. Be careful, you may want to run it low on gas before attempting this, makes it easier. Good luck. Dont forget to rate.

Check gauges light on, Temp gauge at 0, vehicle wont start.

Could be connected, but could also be two different problems.
It could be something in the key switch, or a wiring problem. Or it could be a wiring problem with the temp gauge and something else causing the engine not to start.
Do you have spark and fuel pressure at the injectors ? And does the gas gauge work ?

95 bmw 525i no dash lights no tach no tremp gauge and fuel gauge pegged way past full

Why was the battery missing to begin with? I would start by checking all fuses under dash and Central hub. Check for burned in-line fuses,if any, coming off of battery cables.

Fuel gauge does not work

The fuel sending unit is part of the fuel pump assembly so the first thing I would check is the fuse panel for a shorted fuse.
Next I would check for lose connections on the fuel pump assembly and the instrument cluster.
Hopefully theres a lose connection or you may have to change the pump assembly and they can get pricey.
Hope this helps

I just bought a 98' Tahoe and the gas/fuel gauge does not work. Checked the fuses and tried a new one for the gauges fuse and the gauge worked but then went back to empty. When I removed the fuse the...

The computer does a sweep test everytime it senses power. Check it next time you turn the key to run the gages do a little self test. However the fuse and gage won't be your problem. They are very bad for the fuel level sensor in the tank getting corrupted or dirty and doesn't read properly. You can try to add port fuel injector cleaner to the tank, but problem will usually reoccur. You will need the fuel tank dropped and the level sensor replaced.

My gas gauge does not work at all is it my fuel pump filter or is it something else

Fuel gauges in general are a separate from fuel pump circuits. Usually you start by finding the fuse panel and check the gauge fuse, if the rest of your gauges are working this usually means the fuse for all gauges including temp, oil, fuel are ok. Next you'll have to locate the sending unit wires at the fuel tank and look to see if any are disconnected or damaged and have good clean connections. Next consult a factory manual regarding the method of checking the gauge some companies ground the wire or while others manufacturers require a variable poteniometer usually between 0-100 ohms resistance. slowly turn the pot from 0 through the specs to cause the gauge to sweep from empty to full while watching the gauge making sure it sweeps smoothly. If the gauge is fine the tank will have to come down and a new sender installed, also while you in the tank check that the fuel gauge float does just that floats!

HELP!! Having electrical issues with my 2005 Pontiac

electical is hard to diagnose with out being there. i would treat each problem seperately. first you will need to test the engine temp gauge sending unit. in a dealership this is easy with a scanner they can run a sweep test to se if the gauges are don't want the engine to over heat if the gauge is not working. next problem the dome light should be easy to fixe does the dome light work with the dome switch?remove the bulb and with the doors open and switch on check for voltage, if voltage check connection and or replace bulb. if no voltage check fuses for voltage.last will need to have the dtc po243 checked out by a repair shop. i hope this will help.
