Can you check the fuel pressure?Could be a fuel pump or fuel line filter problem.

It could be a leaking injector also. Do a fuel pressure test, turn the key off & fuel pressure stays where it is (1-4 psi drop is normal) don't worry, there is no problem. If it drops do a fuel pressure test, & if you can block off inlet & return after you get fuel pressure (be sure to turn the key off once you have pressure)you can see if the fuel pressure drops. If it drops, leaky injector. If it doesn't drop with the inlet & return lines blocked off, it is the fuel regulator. Where did you get the regulator you put in?

A fuel pump or filter problem would reduce the fuel getting to the engine, not increase it to cause flooding.
If it drops, leaky injector. If it doesn't drop with the inlet & return lines blocked off, it is the fuel regulator.
"it is the fuel regulator."... Or the fuel pump. If the pressure doesn't drop, it could be the check valve in the fuel pump. If it holds pressure with the both lines clamped try it with only the return line clamped. If the pressure, then drops, it is the check valve. However a leaky check valve won't flood the engine, only prolong the cranking time, maybe.
The "chevy place" spoke out of turn if they told you what to replace without diagnosing the problem. Holding the gas pedal to the floor puts the ECM into the "clear flood" mode where it shuts off the injectors to prevent additional fuel to the cylinders and allows for the cylinders to clear while cranking.

i replaced the fuel press reg. and the old one seemed like the rubber was to soft and spongy, plus it came loose from the center. would fuel additives soften the rubber and make it come apart? it starts fine now with the new one,

munday chevrolet did diagnose the problem and the regulator was what they said the problem was.

Hello
Just so every one knows when you hold the gas pedal to the floor when starting turns off the injector pulse, To help start a flooded motor.

I had the same problem and it was the temp sensor in the front of the block.

If they took the time to do a diagnosis, that is different than:chevy place said it was fuel press reg. so i changed it
