I recently bought a 90 RC for a decent price but the TBI it has is awful. I regularly go camping in the mountains and this thing barely pulls its own weight much less a little pop up. So I just installed a 4 barrel, new distributor and all that fun stuff. The only issie now is the fuel pump only turns on for a split second to prime the line then shuts off. Does anyone know how to wire this so that it will work properly?
