Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be posting a reply ASAP

what is the mileage on it?

the delivery pump in tank is weak or
the injector lift pump is weak .

is there any fuel leak at the filter/water sperator connection, that is common problem , can you check that and let me know?

can you have it scanned and retrieve the fault code and post them back here for me , then i can be more accurate for you.

Please let me know

Thank You
