Two Weird Reasons Why Silverados Have Fuel Gauge Problems

silverado fuel gauge problemsIf you are the owner of a 2003-2006 Chevy Silverado or GMC Sierra and you have fuel gauge problems and your fuel gauge has quit working you’re not alone.  There have been dozens upon dozens of reports of fuel gauges that stopped working on these models in the last few years.  This causes vehicle owners a lot of unnecessary stress and more than a few instances of drivers being stranded along the side of the road after running out of fuel.  Here’s the two most common reasons for this problem.

Silverado fuel level sensor

Deep in your fuel tank lies your fuel pump and fuel sending unit, bathing in fuel and quietly doing their job, until they don’t.  It appears that on the Silverado and Sierra the fuel level sensor which is part of this assembly is prone to failure.  When the fuel level sensor goes out the instrument cluster no longer has any way to show you how much fuel you have.  When this happens you’re left guessing how many miles you have left on your tank of fuel and using your trip meter as a guide while your fuel level gauge bounces around from empty to 1/2 to 1/4 to full and back again.  If this is your vehicles problem have it diagnosed by a local mechanic and repaired as soon as possible.

Silverado Fuel Gauge Problems

The second and possibly more common reason for a Chevy Silverado fuel gauge or Sierra fuel gauge to quit working is a faulty instrument cluster.  A common problem among GM vehicles built from 2003-2006, various gauges in the instrument cluster will fail often affecting higher mileage vehicles.  This problem is caused by defective drive motors used on the circuit board of the instrument cluster itself and has been linked to over 30 different GM models and is sometimes covered under warranty but only if your vehicle has 70k miles or less.

How Do I Tell Which Problem I Have?

If your fuel gauge has quit working and another gauge in your instrument cluster has stopped working as well then you should have your instrument cluster fully rebuilt.  If only your fuel level gauge has stopped or is reading erratically then it would be best to have the problem diagnosed by a local mechanic first to determine if it’s a fuel level sensor issue.
