What’s the problem with my GMC Sierra truck?

Why does my Chevy Silverado not take gas?

Truck was at half tank before I started filling and wouldn’t take any gas in. Tried a different station the next day with same result. Dropped off at dealer and they were not able to find any issue.

Why is my Chevy Silverado transmission not working?

Why does my GMC Sierra take so long to fill?

Question Here.: There is a restriction between the gas fill goose neck and the tank making it accept gas but very slow. It takes about 10 minutes to put in 20 litres of fuel. Can I fix this myself.

Why are my fuel gauges not working on my Chevy Silverado?

In fact, this is,unfortunately, a common problem among most GM vehicles built from 2003-2006 – various gauges in the instrument clusters of these cars and trucks tend to fail as the mileage starts to get into the “high” zone. This problem is caused by defective drive motors that were used on the circuit boards of these instrument clusters.

How can I get my Chevy Silverado to accept gas?

The only way to get it to accept gas is to stand there holding the trigger at halfway and stand very still for about five full minutes.

What to do if you have Def in your diesel fuel system?

Why is my GM fuel pump going bad?

In this tutorial I’m going to show you two different methods to verify if the no start condition on your 4.3L, 5.0L, or 5.7L throttle body fuel injection (TBI) GM vehicle is due to a lack of fuel, which usually means that the fuel pump has gone bad. One method involves using just starting fluid and the other involves using a fuel pressure gauge.

Why is my Chevy truck not filling up?

I was also told that if you overfill the tank, and top it off, it could flood the valve with raw gas, instead of just fumes, which will damage the valve, so I will not be topping off my tank anymore.

Why is my Duramax diesel engine not working?

The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate.
