"disconnect the harness from the fuelpump cutoff switch in the trunk....and then start the car (if it even starts mine never does) and it will use up all the gas left and u should be good"...
Yep, thats the quick and easy way... then just for kicks, start the car agian, and make sure it quits, and wont start agian, prime to pump and couple times too... Then you can go to the fuel rail and press the valve in ( with a rag on top)
Then your good to go.
