low rail pressure and voltage

jeudi 4 septembre 2014

Truck started throwing these codes several months back. Figured the low fuel rail pressure could be cured by the airdog 150. Not the case. Truck wont hold fuel rail pressure even with the programmer on stock and normal driving conditions. Truck also takes longer than normal to turn over not sure if the that's due to the low system voltage or low fuel rail pressure. Any suggestions or help would be appreciated. Thanks in advance.
