Smell the dipstick if you smell fuel in the oil you need to find out where it is coming from. How old are the plugs, wires, PCV/breather filter, cap/rotor, run a compression test and check the fuel pressures. Run some good fuel injector cleaner for a couple tanks of gas. How far does the spark jump with a spark gap tester you want at least 3/4 of a inch.

First, holding it to the floor puts the computer in "Clear Flood" and shuts down the fuel injectors. Holding it part throttle will help more.

Second, try priming the pumps a few times. Turn the key on, count to 5, shut it off. Rinse repeat 3 or 4 times and try to start it. If that helps go do the dealer and get a new "fuel reservoir". It has the anti-drain back valve that is probably shot and letting all your fuel pressure bleed back out of the lines over night.
