I have installed new pump, made sure I was getting 12v to rear of car, new fp relay, all fuses are good and still no fuel pressure. If I use test connector fuel some out of fuel canister, what is that all about. Does that point to fuel pressure reg? This is 2nd day I'm chasing this no fuel pressure issue. Not getting any fuel at rail, I was last week when I was trying to fix, but now I don't get any fuel at rail. Driving me nuts as all else has checked out.
