How do i get the fuel tank ring off 2005 gmc envoy

Google the question & look on the internet

I bet your going to drop the fuel tank, if you have
issue with either

Better use a professional scan tool & smoke the evap
system, to do the proper testing before, you do a hard
job for no reason or no testing to find a problem

Get the codes then google them

The fuel level sensor is in the gas tank, and if it needs to be replaced, the tank must be removed from the truck.
Does your gas gauge work correctly? If not, there could be a bad connection at the tank/sensor or the sensor itself is defective.

Yes, in vehicles with the fuel pump sending unit in the tank, you have to drop the tank to replace the parts there.

It is installed in the fuel from the top of the tank so the fuel tank has to come out. You have to disconnect the electal plug, the fuel lines, the filler tube and EVAP hose and unbolt the fuel tank straps. On some vehicals pulling the drive shaft is a must some it just makes it a lot easyer. The sending unit is where the fuel lines and wires go into the tank.

Your fuel pump is located inside the fuel tank of your Envoy. It can only be replaced by removing the tank, then taking the pump out of the tank.

First check to see if you have a fuel filter. It will be located between tank and engine. Apparently, some Envoys do not have a filter, just a screen mounted on underside of fuel pump which is in fuel tank.

most likely need a fuel level sensor
you need to remove the fuel tank then remove
remove the fuel pump module
the sensor is on the side of the fuel pump module (the float is part of the sensor)
hope this helps

You will need to replace the fuel level sensor which is in the fuel tank.They have a lot of problems because the metal fingers on the sensor wear off and gives you the incorrect readings.This will also cause the check engine light to come on.You will probably have a level sensor code.This will be a lot easier if the fuel level is down to about a quarter tank or less.Also you should be able to get just the level sensor and not have to get the complete fuel pump module.Good luck.

Check your fuse, if the fuse is fine, check for broken wir or unplugged connection inside or out of tank.

You will need to remove the fuel tank from the truck and replace the fuel pump/fuel level sensor module that is inside the fuel tank. Use extreme caution when doing this as there is a real fire hazard.
