97 Ford ranger 4L V6 here
I'm having a hard start issue, but the truck runs great after starting. If I prime the pump a few times first I have no issues. If I don't prime the pump first then the truck will take 3-5 seconds to crank.
Ran a fuel pressure test today and findings are below.
When I first turn the key to the on position the gauge reads about 10
Second prime the gauge reads 20 and third prime the gauge reads 30
This is what I believe is causing my issue.
While running the gauge reads about 28 and gauge doesn't fluctuate at all if I'm revving the engine or maintaining higher rpms (no tach so no idea what I had the rpms at)
When I remove the vacuum tube for the fuel pressure regulator it reads a little over 40
With that being said, I'm having a hard time verifying the correct specs for this pump and am seeing a lot of differing information. Am I need of replacing the fuel pump or is there something else I should be looking at before going to all that trouble?
Thanks for any help!
