88 lx 5.0 speed density problem

Car wont start, started out with a fuel pump wiring short, fixed that, now it wont start . Starts with a 4cyl pcm, just not the v8. I even bought a new v8 pcm

I suppose I had a bad pcm relay. When I hit it it would reset and prime the fuel pump. I put an extra relay on and it started right up.
