2009 Pontiac G5 won't accelerate properly on hwy when low on gas	Sign In

I took my car in to a GM dealer and they replaced the fuel tank due to a leak. The cost was under covered under a special recall via GM. Now when the car is low on gas .. (Say about 50-60 miles left on a tank, or lesss) and I'm on the highway the car will not accelerate. When I try to speed up the RPM's drop and it seems like the engine isn't getting gas? almost like i'm running out of gas. I can still drive on residential streets going up to 40-45 mph but when i get on the highway it won't continously drops and won't let me get up to speed.

Brought it back in , they replaced the fuel sensor... but that still is not fixing the problem.

Below is link to a video of what it does.

Notice the RPM dropping..the whole time im trying to accelerate and pressing down on the gas pedal

I wouldn't be driving it that low on fuel in the first place. That's the best way I know to ruin a fuel pump.

Same - you probably already killed the fuel pump. Low fuel, hot pump = failure,

Obviously, you need a fuel pressure gauge to confirm anything.
