do i need a new fuel pump
so my camaro will shut of in the middle of the road sometimes but will start right back up after like 10 mins and when i hit the gas pedal the car doesn't accelerate right it will go real slow until i finally get around 40 mph. but when i stop at a stop sign or a red light it just does it again. I think i need a new fuel pump and a new icm am i right.

Re: do i need a new fuel pump
Can you tell us some specifics like engine size and whether it is carbureted, TBI, or TPI?

Re: do i need a new fuel pump
TBI = throttle body injection and TPI = tuned port injection. Being it's a 3.1 you probably have injection of some sort, but not TPI. Don't know much about the V6's, but to rule out the fuel pump, disconnect the fuel line from the engine and attach a pressure gauge and check it. The correct pressure you can find in a service manual or a Chilton's or Haynes manual. If you don't have one of those, I recommend getting one. You can pick them up for about $20 at your local auto parts supplier. Could also be a fuel pressure regulator.
