Attempt at test running a Magnum

Get a fuel pressure gauge and screw it to the fuel rail test port. (Napa auto zone etc) they are picky about fuel pressure. Fix the leaky regulator. I had to ground the jtec ecu (2001) on my test stand for it to be happy. If you have fuel pressure, and the ASD relay is powering injectors/coils AND the fuel sync hasn’t been messed up it will fire.
