Disconnected battery, now fuel, temp gauge won't work

I disconnected the battery and cleaned the terminals and connectors and when I put everything back, the fuel gauge and the temp gauge will not work. Battery light stays on. Oil Pressure and Volt gauge are okay. Any ideas? Had the battery and alternator checked. Autozone tried to see if it pulled any codes,said everything was fine. I have a 2000 Olds Bravada.

If all the other gauges are working, then it is definately the sending unit. Mine is out at the moment and has been all summer. Pain in the **** to fix so haven't yet. Have to know however cause the fuel pump went out. Gonna kill 2 birds with 1 stone. We have just been using the digital reader for fuel used to know how much gas is in it. The gas gauge will bounce between half and full but never go below half.

Okay .. had the EXACT same problem - word for word .. turns out, that my positive battery cable was corrodid badly.. the ignition switch wasnt getting any power or signal - so it didnt know the trans was in park, so it locked the key in place... and all power cut off obviously because no juice was going thru the cable.
Apparently however.. you will get almost the exact same symptoms if the ignition switch burns out... so first test the battery cables themselves.. if they are fine .. then plan on replacing the ignition switch.

SOURCE: temperature gauge not going above 100

I would replace the thermostat and temperature sending unit.

SOURCE: Silhouette will not start, but battery put out 12+ volts

You better have the alterntor checked, you said the battery was putting out 12v. was that with the car running or off? If it was running, it should have pushing between 14 and 15 volts, if it wasn't with it running, replace alternator.

It a 98 ranger xlt was having idle problems and it pulsated while driving at study speed say 40. I disconnected that sensor by the t.stat and those problems went away. Now dont want to start after running....


Scrape spade to bright metal, clean connector with toothpick put connector back on Clear codes, one way is to leave positive battery terminal off overnight. The brain(ECU) must have the
temp information to start and run. Without excellent connection
It doesn't know what to do.

Replaced battery and now the temperature gauge stopped working.


Usually, there are two temp sensors on the block. Depending on the car the one that controls the temp gauge is near the front of the block and connection is problematic. It may be in the region of the battery and become disconnected, and or I am finding bad connection due to corrosion or perhaps battery acid in your case? Double check the connection polish spade and try to clean connector with a tooth pick.

Fuel Rail Pressure Sensor Circuit high input.
1. Unplug the negative battery terminal connector (black one, NOT red) from the battery and set aside. Doing this will also reset your check engine light as well.

2. Unplug the fuel pump fuse. Check owners manual for proper location in underhood fuse block.

3. Start vehicle and run it until it dies to relieve pressure.
4. Disconnect the electrical connector to the sensor on fuel rail.

5. Remove bolts to fuel rail pressure sensor.

6. Disconnect hose on back of Pressure Sensor.

7. Once everything is disconnected, pull straight up on sensor. Be sure to pull up with a little effort, it has a snug fit. Of note, you will see gasoline when you lift up the FRPS so be careful so as not to let debris fall in there.

8. Install new FRPS and reconnect hose and electrical connector.

9. Put the fuel pump fuse back in.

10. Reconnect negative battery terminal.

11. BEFORE YOU START THE VEHICLE, you need to prime it. Do this by cycling the key to the ON position and Off position several times for the fuel pressure to build back up . Do this 2-3 times then start your vehicle.
CHECK FOR LEAKS, TEST DRIVE FOR ABOUT 10 MILES OR SO AND BE SURE EVERYTHING IS OK AND CHECK ENGINE LIGHT DOES NOT RETURN.

It will start when cold, and after driving and then parking, the starter will not turn over? Replace your starter/solenoid.

WARNING: WHEN SERVICING THE STARTER MOTOR (11002) OR PERFORMING OTHER ENGINE COMPARTMENT WORK NEAR THE STARTER MOTOR (11001) , BE AWARE THAT THE HEAVY GAUGE BATTERY INPUT LEAD AT THE STARTER SOLENOID (11390) IS "ELECTRICALLY HOT" AT ALL TIMES. BE SURE TO DISCONNECT BATTERY GROUND CABLE (14301) BEFORE SERVICING STARTER MOTOR .

Fuel gauge/temp gauge not working


There are two sensors, one for ECU temp. readings with two pin connector and other one with only one wire, which has been probably disconnected when you replaced the CPC solenoid - very close position.

Fuel gauge, temp gauge, and auto door locks stopped working while in transit. checked obvious fuses, found no problems. did not check all fuses. Ideas


I had a similar problem with a 2001 Saturn. We checked every fuse and they were all fine. We finally did a 'reset' on the car's computer by disconnecting the battery and reconnecting it a few minutes later. Everything was back to normal after that.
