Hi and thanks for using 2CarPros.com.

If an engine fails to start when the starter engages and turns it, there are only a few things that can be wrong, no fuel or air to the engine, no spark from the ignition, ignition timing or broken timing belt, low compression/no compression. Take a look through these links which describes different causes for no start or hard start issues:

https://www.2carpros.com/articles/car-cranks-but-wont-start

Now, I need you to check for both spark and fuel to the engine. Here are the links which describe both:

I have attached a picture which contains the manufacturer's fuel pressure specifications.

Let me know if you have questions or need additional information.

Take care,
Joe
