Car sputtering and stalling

When I drive my 2010 SS for about 45 minutes it starts to sputter and will eventually die. When I let it cool down it starts back up and happens again. I'm thinking it's the fuel pump. Does that sound right? I'm thinking it's over heating. Only thing done to the car is it's tuned. I'm thinking it might be trying to pull too much fuel and it can't keep up and it's on it's last leg. Time to get a ZL1 fuel pump??

That sure sounds like an overheating fuel pump.

Could be the fuel pump. Are you not getting a check engine light? If you are, make sure to get it scanned and figure out what the code is saying. Don't go out buying parts you don't need in hopes of fixing a problem. There are many reasons why the car is doing that, so make sure and have it figured out first before you go buying things for it.

I had a check engine light the other day. On star scanned it and it came back something along the lines of "fuel system delivery messed up". Not sure exactly what they said, I have it wrote down somewhere. I looked under the hood and realized when I took my air intake off the other day I forgot to hook te line that runs from the air box to what looks like the fuel rail. I hooked it back up and the light went away. Then yesterday I had the problems I originally talked about. It happens when I lightly start to get on the pedal. It bogs down and sputters and shifts irrationally. Any ideas? I was just thinking the zl1 pump because I'm having a nitrous kit put on it and I'll be putting bigger injectors on then.

Jcunningham, are you saying the SS and zl1 have the same fuel pump? I read a lot of posts yesterday saying people were swapping them because they pumped more. Not questioning you but I'd love to know.

You need to put a gauge on it to see if it is your FP.

I wouldn't jump at the fuel pump just yet. There's a bunch of things that should be considered. You need to check everything from the pump to the injectors.

You say the car was tuned, ?
Did you pickup a bad tank of gas, the fuel system don't like water.
how's the fuel filter?
Do you have a bad cylinder coil?
Bad or clogged injector, do they need cleaning
etc, etc, etc.

Last year my trailblazer started running rough. I envisioned the tranny was shot or the engine. It has almost 100k miles and is a 2003. Turned out to be a bad cylinder coil. Changed the bad coil and all 6 plugs, runs like a charm.

Last time I suspected a bad fuel pump in a vehicle I made damn sure that's what it was before I spent the $300.

You could try something simple to diagnose.

IIRC there are over 80 readouts provided by the Camaro.
