I just acquired a 35th SC but I have a no crank no start condition , battery is good, previous owner replaced crank sensor. I can turn over the engine by jumping terminals at starter relay but it still won't start, at the key ignition itself, it doesn't crank the engine over but you can hear the fuel pump prime. What else should I look for? I was hoping that leaving the ignition in the run position and jumping the relay would result in a running car but that didn't happen. Any suggestion would be appreciated
