Need help, possible fuel pump problem Hey guys, I'm posting this up for a friend. He has a 2002 SS with an MS4 and bolt-ons. He is only running an email tune and said the car is running a tad rich.
The best explanation of the problem is that when he is driving the car at a normal rate, the gas pedal seems to be normal/soft, but the minute he begins to accelerate or flat out floor it the pedal begins to harden and will not accelerate. When he stomps on it outright, it goes nowhere. I know this is vague, but those were the best possible symptoms that he could gather. Could it be a passing fuel pump or some other fuel related part? Please post any ideas/suggestions.

He says the pedal feel changes??? That's really odd... Torque Management settings maybe? Without seeing a tune, it may be hard for someone on here to diagnose that.

Much thanks for the suggestions. After calling around to some shops, someone suggested that it might be traction control related. Any other ideas?
