My fuel pressure reads 35psi when it is running and when I shut off the fuel pressure slowly climbs to 39psi after 15 minutes its starts to go down. After a ½ an hour or so it about 5psi is this normal. I ask because sometimes when I shut it off and go in the beer store and try to start again I have to crank it for like 5 to 10 seconds till it starts. And when it starts I can smell fuel. I put on a new fuel pressure regulator and it does the same thing (I put the original back on) In December I put in a new fuel pump after it went bad. It seam to me it stated to do this when after I changed the fuel pump. I got the fuel pump from my local ford dealership.

I’m going to try changing the fuel filter to see if anything changes. Or maybe I should stop going to the beer store. Thanks for your help

I would do some injector leakage testing AFTER I determine whether there is a leak in any of the fuel system O-rings (which it sounds like you may have since you smell gas).

I don't smell gas all the time it's only when it's been shut off for a short time an i go and try to start it. sometimes its start as soon as i turn the key. Sometimes it takes 5/10 secondsto start. That's when I smell the gas. when it takes 5/10 seconds to start.

If the pressure is increasing after you shut it off you may have some vapor lock going on.
Ford EFI cannot vapor lock.

Ooops. Should learn to read the Bronco info tag.

The issue sounds like a heat soak problem.

Have you checked fuel flow, not just pressure. Plus you should try and check the pressure and flow during one of your no start conditions if possible.
