Answer
What is your fuel pressure when the ignition key is turned to the ON position ONLY, WITHOUT trying to start the engine.

You will need to install an external fuel pressure gage on the fuel line to see the pressure.

Check to see if you have spark to ALL the spark plugs as you try and start the engine.

See if it will start after it cools down after a few hours.
