Default Fuel Pump????

My 1994 Corvette was acting like it was flooded when trying to start. I would prime it 3-4 times to get it to start. Ended up replacing the fuel pump and seemed to fix the problem. However month later I am getting the same thing again. Started one time and died when I hit the gas. Now just acts like it is flooded.


Any thoughts?

Read that wrong, sorry for what I wrote at first. Have you checked the fpr, injectors, and a good blue spark at the plugs?

Your post is contradictory. You said "flooded", which is too much fuel. Then you said you primed it several times, which sounds like not enough fuel.

If it's really flooded, hold the accelerator pedal to the floor while starting. That will put the ECM in "clear flood" mode, which basically turns off the injectors.

Also, did you re-use the old fuel pump pulsator? The general consensus around here is that it is not needed on our cars. Ditch it and run submersible fuel line in its place.
