    Could be, can you hear the fuel pump prime when you turn the key on? Not nice to the fuel pump to run low/out of gas. Did he put a fuel pressure gauge on it? Not sure on LT1's but LS1's should show 58-60 PSI. Hope it's not the pump, your mechanic sounds like he has the right ideas.

    Does the engine turnover when you turn the key? If the engine isn't turning over at all it wouldn't be the fuel pump.

    Get under the car, by the gas tank and listen.

    Get someone else to put the key in the ignition and turn it ahead to the power on position. Do not turn it far enough ahead to make the engine crank.

    You should be able to hear a whining noise from the fuel pump when the power is turned on.

    I have had many fuel injected GM vehicles. On occasion they have run short of gas and I never had any problems with burning up the pumps. I did have a problem with a clogged fuel filter and poor flow due to picking up all the dirt contained within the last bit of gas in the tank.

    Me too. I have two friends that messed up their pumps/one fried and one just the sending unit - both went to a local shop for repair and they cut a hole in the rear deck instead of dropping the tank, easier to replace if it ever happens again...don't ever want to have to deal with it.
