Engine Mechanical problem
1998 Volvo S90 6 cyl Two Wheel Drive Automatic 250000 miles
had a new fuel pump installed, in tank, about 7 months ago. Now, it seems the same thing is going on, though it seems I have pressure in and out of the inline filter. Disconnected the out line of filter, turned key, good fuel flow. No pressure to injectors, I think. Regulator? If so, how to replace? Other suggestions? Thanks.
