Description: Fuel Delivery Pressure below Critical
Troubleshooting:
Fuel Delivery Pressure (FDP) is a measure of the amount of fuel pressure that is entering the
fuel injectors.
Probable causes:
1) FDP below 70 psi (483 kPa)
2) Dirty fuel filter
3) Aerated fuel
4) Restricted or open fuel supply line
5) Low or empty fuel supply tank
6) Biased low FDP sensor signal
7) Failed fuel pump
