Hi, I'm Dan.

An engine needs five things to run, spark, fuel, air, compression, timing. I've added a couple videos that can help narrow this down for you.
Is there any codes stored in the PCM? Here is a guide that will help with pulling codes.

Next we need to run through this guide that will talk about this issue in more general terms and cover the things I mentioned above.

Lastly, I suspect this is a fuel pressure issue so we should start with that.

This guide will take you through checking the pressure.

Please let me know what you find with this. Thanks

If you have Cam and Crank sensor correlation codes then most likely the car is out of time, meaning the timing belt could have broken.
This can be bad for the engine because the valves will then contact the pistons and can bend all the intake and exhaust valves causing internal engine damage.
Can you check the timing belt? Remove the belt cover to see if the belt turns when the car is cranked over?

I attached the printout showing the upper timing cover. You should be able to remove this easily.

Can you take a compression reading on the cylinders? If the compression is low, you would then have to check the timing.
