Do you still hear the fuel pump running after you turn the key off? if you do then yes it could cause a flooding problem, but with the age of the rig I am leaning towards leaking fuel injectors, you could find out by running a fuel pump pressure tests and see how long it hold pressure after turned off, if it bleeds off really fast, block off the fuel return line and retest, if it still drops and won't quit falling then you have some leaking injectors.
