First of all, you shouldn't be fueling your vehicle while it is running. It is dangerous for you and everyone else on the fuel deck. Second, your fuel cap is part of the EVAP system. When you run the vehicle with the cap removed, the computer perceives a mass leak in the EVAP system. It is supposed to set a code and turn on the check engine light. If you regularly run your vehicle with less than 1/4 tank of fuel in it before filling, it will cause premature failure of the fuel pump. The pump is inside the tank and is cooled by the liquid in the tank. If the fuel level drops below 1/4 tank, the pump is no longer submerged, it cannot dissipate the heat and will overheat causing it to burn out over time. This is not only true of your vehicle, but every fuel injected vehicle with the fuel pump inside the tank. most of your problems are operator error, and I suspect that the fuel pump is also.Report it
to comment to moogvo your right about everything even not letting them go below 1/4 tank. But pump failure is inevitable, their is even a recall on it (finally) but even with the recall at the dealer it still cost a couple hundred dollars. and by the way!! I'm a used car dealer and I've had NOTHING BUT TROUBLE with Envoys and Trailblazers!!! I won't even buy them anymore. With low miles or high miles doesn't matter, I've even had GM technicians tell me they would never buy one. I've spent my last penny on them. I wouldn't do it to my customers I don't care if you buy a car from me or not when customers ask about them I tell them the truth and let them know I don't care if they buy from me just don't buy one for your own sake!!till cost you a couple hundred dollars. and by the way!!Report it
