Check your " FUEL FILTER " for clogging. Work backwards toward the fuel supply tank, Hope this helps.

SOURCE: low fuel rail pressure

who did a conversion on this truck???? the duramax is a common rail engine and can not handle wvo or sve. it will destroy your entire fuel system in no time on this truck. if you want to do a vo conversion you need to get a diesel with an inline injection pump or one of the older powerstrokes. i would suggest you quit trying to run wvo through this truck if you do not want to do a lot of very expensive damage

SOURCE: Low pressure at the fule rail, changed out the

if you getting low fuel pressure after changing out the fuel filter and the pressure regulator, than the fuel pump may not pump correct amount of pressure. being 1993, the pump has age along and have run many miles, may have gotten weak and not pumping correct mount of psi.

SOURCE: 2005 Lincoln Town Car suffering from low fuel

The ford spec listed in the ford engine control manual is:

General Specifications Item Specification Fuel tank capacity 71.9L (19 gal) Fuel Pressure Hot restart 448-482 kPa (65-70 psi) Key ON Engine OFF (KOEO) 140-415 kPa (20-60 psi) Key ON Engine Running (KOER) 170-280 kPa (25-40 psi)

Are you measuring the fuel pressure with a mechanical gauge or are you using a scan tool . If with a mechanical gauge, does the gauge have an air purge? What symptoms does the vehicle present. If running rough you could have a fuel injector leaking. Are you measuring the fuel pressure with the key on engine off? If so, did you cycle the key a few times? Good luck

I'm getting a code for low fuel rail pressure


you can try to erase the fault code with your obd2 scanner, after a period of time, check it, if you get the code again, you must take it to repair.

My 03 duramax started fine this morning but only ran for a fiew minnuts then shut off on its own and now it wii turn over but not start it seems to have fuel pressure can it be cam sensor or crank sensor...


To start with, a Duramax Diesel runs on an excess of 20,000 Psi of fuel pressure. Unless you have some specialized equipment,(and know how to use it) I do not know how you could possibly tell that the fuel pressure is OK.

Duramax Diesels also have had a lot of problems with glow plugs. This could explain why it will not start. Then again, it COULD be something totally different like a bad sensor. This could even be caused by a faulty fuel pressure sensor or a bad fuel pressure regulator.

The best way to find out is to scan the engine computer for fault codes and read the engine data from the computer to see if all of the sensors are providing the correct input to the computer.

There is a service bulletin for this condition.It has to do with a ceramic high pressure valve ball fracture inside the fuel injection pump,which may lead to internal pump damage resulting in low fuel rail pressure.This could contaminate the fuel rails and injectors with debris.The fuel pump will operate but with reduced output flow.The fuel injection pump will have to be replaced or repaired.Look and see if there are any repair shops that specialize in injection pumps.Hope this helps.Good luck.
