2000 V70 not holding fuel pressure

tombrisk · Post by **tombrisk** » 28 Jul 2020, 09:07

Usually have to crank 3-6 seconds
New: fuel filter 200 miles ago
Vid shows 52ish running, several on/off cycles up to maybe 30ish with several tries
Then bleeds off
Q: What's the most likely cause/fix?
The long crank is my concern
Thanks!
Oops- can't attach .mp4
1st On: 12psi
2nd: 32psi
3rd: 42psi
Start: 52ish, slight fluctuation

Sounds like fuel pump is failing. I has same symptoms on my v70.

Yeah, dang
One (tiring, messy) search result mentioned a non-return valve.
Thoughts?
