On my crx my fuel pressure regulator keeps failing. This is probably the 7th one ive put in. the stock one went bad at about 150k and put aftermarket ones in that kept going bad. i ordered a oem and put it in and it worked longer than the other ones (which was only for about a day). the aftermarket ones would work for about 5 min then i would lose pressure. symptoms car runs like ****, sounds like a lawn mower from it misfiring, cant get past 40mph. no cel, basically just the things i just listed. could there be a vac leak somewhere causing it? it gets pressure when i start it up but after about 5 min it loses all. no pressure when i turn the car off either.
