Default 1988 F-350 7.5 liter EFI

Engine appears to be getting to much gas and will not start. Plenty of spark and no codes.

Make sure to check the fuel pressure reg for a leaking diaphragm, fuel will be pulled up through the vacuum line in to the intake. All S plugs wet with fuel?
If no apparent codes, or management overfueling, good hot spark, and if the reg proves out, have you tried peddle clearing the flood?
