Low fuel pressure on rail on code reader

[ian cooper]

I was wondering if anyone else has had this problem.i have had pump/sender unit replaced on e270 and I am still getting the same reading,any ideas?

the o-rings of the low pressure lines, plastic lines themselves, pressure regulator of the rail, pressure sensor of the rail, injector leak... should have more detailed codes and/or perform the individual component tests.

Edit: what you mean pump/sender unit, has high pressure pump refurbished? When fuel filter has been changed? Make a leak test for injectors. can be done without wny special tools.
