Blown up computer or fuse
Ok I have a 1988 f-150 with a 4.9 I6 and I had a small exaust leak that was where the cat and the two tubes that go from the exaust manifolds and it was welded on and now I have no fuel pressure and the pump doesn't kick on and it's a brand new pump and I can no longer pull codes from the computer with a jumper wire on the check engine light or a test light

Yes and it stays on but when it turns on it fades in it doesn't just turn on like usual and i know for a fact it has one code for a neutral drive swicth but it ran fine before and it wouldnt turn the the check engine light on it would only come up when you tested it

Start checking battery connections and grounds. I'd also try swapping around your relays and seeing if you can elicit any kind of change.
