Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
In allot of cases this model can be common for a restricted fuel filter that causes this issue here.If this was not replaced and your not sure when it was replaced last I would replace it and see if this resolves the fault.If this does not resolve the fault or was already replaced let me know.

Have you had the fault codes checked at all with a fully compatible scan tool for your model?
On some models there is a low pressure fuel pump in the fuel tank that fails.I dont have the complete data for your model here but yours may have one like most and it sounds like it may have failed to provide the low fuel pressure to the fuel filter then to the injection pump.I would have this tested further to see if this is the case for sure here and the low pressure pump replaced as needed.
Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.
In most cases it is usually the low pressure fuel pump in the tank.I havent seen any relays fail before myself that had caused a no fuel issue like this here.
