N14 gremlin

[Boatymkboatface]

Hey everyone glad I found a forum that might be able to help. So to make a long story long. N14 525, came in for head gasket leaking. Block pitted. 25,000hrs on it. Log truck. Pulled motor and sent it out to get surfaced and line bored. Did the build and re-installed motor. Could not get the thing to start for the life of us. Gone through every diagnostic possible. Will not fire up unless you give it a little shot of ether. Then it runs like a top. No smoke no nothing. At cranking it wasn’t getting the minimum 25Psi of fuel pressure off the pump. So sent it out and got it rebuilt. Still only getting around 5psi. I believe the pump needs to be replaced with a new one but We also don’t want to throw 1000$ at it. Any help would be great. Anything.
