问：发动机曲柄但不会启动。

汽车运行良好，没有问题。下次我去开车时，它会摇动，但不会开火。毫不犹豫。自由翻身。但甚至没有溅射。在接下来的几天里，我尝试了几次，结果相同。我拉了并检查了所有发动机舱保险丝。一切都很好。试图再次重新启动并相同的结果。我从燃油压力传感器上断开了油腻线，以检查气体。 There was none. Reconnected I then rented a fuel pressure tester from Autozone. I hooked up the gauge and turned ignition to "on" but did not try to start the car. No pressure registered, Not sure if that is normal or not. I then tried to start the car. It sputtered briefly and then started right up! Showing around 35 psi. Test drove and and it ran fine. So far it has continued to start without issue. Is it possible that just hooking up the gauge did something? Relieved pressure, airlock or something?? Or was it just a coincidence?
