Q: My car will turn over but will not start and it started after I added oil.
I bought the car 3mos ago. It needed 1 new spark plug (but when I get it done I’m going to do all of them). I have not got them done yet. All I did was go get an oil change. When it started getting cold here in GA about a month ago, every time I would start the car, it would lag (it would start, then go quiet like it lost power, then run fine). Well about 2 weeks ago, the oil light came on. So I added a quarter of a quart of oil to it. When I started the car after I added it, it made a whizzing sound and the oil pressure gauge started going up and down, both lasting about 60 seconds. After that, the car ran fine. Well 3 days ago, the oil pressure light came back on. My husband added the rest of the quart of oil to it and after I tried starting the car. It turned over but would not start. We tried 3 times. Then we waited until yesterday and tried again. Still the same thing. But I noticed there is like a foamy oily substance on the right front side. Almost in front of the car.

There could be an issue with the oil level and/or the oil pressure. But, the oil pressure can only be measured once the engine is running. If the engine won’t start at present, the best course is to request ano start diagnostic而且，一旦发动机运行，机械师将有一些迹象表明它是否可靠地运行或是否还有其他问题。如果您试图自行诊断NO启动，请首先确认没有激活发动机固定器系统（安全系统），从而阻止汽车启动。如果固定器系统打开，您可能会看到安全警告灯。如果警告灯打开，要暂时覆盖固定器系统，请参阅这些instructions。如果发动机以足够的RPM启动，请确保燃油箱中有足够的燃料，并且燃料不旧。下载已存储的任何OBD-II故障代码，并检查这些代码以找到诊断线索。检查是否有足够的燃油压力，喷射器操作以及火花塞处的火花。基本上，如果起动器电动机以足够的rpm迅速转动发动机，但发动机不会捕获和运行，这意味着发动机的点火，燃料，空气感应或机械故障必须是必须的修理。检查是否存在真空泄漏，诸如闲置空气控制阀之类的空气感应故障，或者考虑燃料，检查是否有失败的温度传感器，该温度传感器必须正常工作以发出PCM的信号，以使混合物在冷启动下富含混合物。其他可能的没有开始故障的是低压，火花塞有故障，线圈有故障，曲轴或凸轮轴位置传感器，节气门位置传感器失败以及正时皮带破裂。不管是什么根本原因，如果您要求no start diagnosticthe responding certified mechanic will get the problem diagnosed and repaired for you promptly.
