Motor swap help

Hey everyone. Have a 91 150 that had 5.0 in it. Got my hands on a 89 250 complete parts truck. Did the swap. Motor won't start now. Have power to injectors just no pulse. Fp won't kick on whe cycling the key. 89 had HP fp onthe frame rail 91 does not. Used computer from 89. Please help. Trying to get this done in the next 2 months so I can bring it to the mud runs. Thank you in advance.

The engine harness is the same, unless someone tampered with it along the way or for the obvious reason of you swapping a v8 for an i6 or vice versa.

So, what engine did you have and what do you have now?
