I agree pump is going South. Also are you using Ford Filters??? If not you should be!! Hard start might be a glow plug or 2 going bad also. Run a scan tool and see. If not you can pull each glow plug out and use a meter to check it out. Be careful not to break the harness.
Hope this helps.

i changed the pump and i always use ford filters. i am changing the filters tonight for a good measure. my issue was stiction. iv got some REV-X and i will be changing my oil tomorrow and putting some of that in as well.

well iv been seeing close to 70psi with my blue spring. i saw 75 once but it came back down once it was started

I get 62-64 on warm days, cold days (30 or lower temps) for some reason it shows 70 psi and stays there.

I had some stiction issues also with 15-40 dino, switched to t6 with hot shots and stictikn is gone even down to -15f temps. Im thinking your fuel system will be cine after the filter change, me also still thinks you got an air pocket in your sending unit causing the weird psi readings.

It might be but it's not a line like you have it's just an adapter fitting.

your sending unit has an air pocket that cant get out because it it is above the bottom of the fuel bowl.

Well how do I purge that then?

It's slowly going to 85psi now. All mine is a little adapter price for the isspro gauge

I havent heard of isspro senders going bad but that may be the case also. I went through three gs senders before i got one that worked.

Thats sucks cuz your fuel system should be fine now but the gauge is acting up.

Well I hooked up a mech gauge that the ford techs use and it's making like 35-50psi sporadically. So I gotta pull my regulator apart to see if anything go messed up when I did the blue spring

I pulled the regulator apart and nothing at all. Still is only making 35psi. I am so stumped!!! Unless I did the blue spring wrong on it. Everyone I see doesn't have a black cup like mine does. Any info there?
