See if there is no spark

Our next step is to see if the oil line is clear? Find the oil line test point on the engine and start the car to see if it supplies oil? See, no oil supply either.

Try it and see if you can start the vehicle? The result was a successful start, wasn't it easy? Learn a little car repair every day and do it yourself.
