Sending unit for the fuel gauge is rarely available these days alone. Most require purchase as a unit (fuel pump and sending unit combo). It has become increasingly difficult to get around this.

To save the most money you can purchase the part yourself. You'll have to find a repair shop that allows you to supply your own parts. Some won't allow it as it cuts into the profit (usually claiming no gurantee of work if they don't supply the part). I know this being a technician in dealerships anda private shop owner for many years.

Compare prices between multiple part suppliers in your area (such as NAPA, Autozone, O'Rilley, Advance Auto, etc.). You can call around or check their prices online. Be sure to compare warranties.

Ask each prospective garage 1) shop hourly rate, and 2) flat rate for the job on your particular vehicle. Each and every job on a vehicle will be listed in the flat rate manual, broken into 1/10th hour increments with adjustemnts for special equipment, such as engine, power steering, air conditioning, etc. Multiply the shop rate x flat rate for your job. Compare this between shops. There will be a slight difference in the flat rate (time allowed) amount depending on if the shop uses a flat rate manual produced by Mitchell's, Motor's, or Chilton's (usually one of these three). Of course a lot of these have now gone to a computerized system rather than books, but the end result is the same - just faster & more convenient.

If your estimates vary quite a lot in time charged then something's wrong! While rates vary between these books it is very little.

This can all require a lot of work on your part. My suggestion is to find a local independent shop with reasonable rates that friends / co-workers recommend. Do NOT take it to a dealer. I worked for them too many years to recommend that!

2006 GMC Envoy XL gas gauge reads empty after filling continues reads empty and the light is on then the check engine light came on what can be the problem how ca i fixe it to save mesome $$$

It is most likely your fuel level sending unit has gone bad. It sits inside your fuel tank to tell the fuel guage how much gas you have in the tank.

The sending unit for the gas gauge is in the fuel tank and part of the fuel pump module, it is not sold seperately. Price is around $350.00, 2 hours labor to install the part.

Gas gauge problems

Common problem on the 03-06 Envoy instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Envoy fuel gauge problems
