I have a 94 chevy C1500 and just got the fuel pump changed in the gas tank.When I hit it and get to 30 to 35 mph, it starts sputtering and losing power like it's out of gas or about to shut off. I can drive steady at 30mph and let it climb gradually, and it won't sputter until i push the gas harder. Can somebody give there opinion on what this might be? Can't risk it going out and I have to miss work again.Don't have much time left.

Thanks

 

If it is not fuel related...


You could have a blockage in your exhaust system. Would start by checking catalytic converter.

 

did you replace the fuel filter at the same time? could be clogged.
