Last night, me and a friend finished wiring the valver. Key on, but pump not priming. Tried a different relay (was using the one from my Nova GTE engine), checked the ECU for codes, but nothing. Then, I decided to crank the engine to get oil arround, and... the pump primed on cranking. Conected the fuel lines, cranked again and it starts! What’s going on? Should this be happening?
