To get the discussion started...
What is the mileage and general history of your car? Car driven gently or hard? Any mods?
Check coolant level. Any history of coolant loss?
Check compression. 135 is about minimum to start engine. 170 is good. Imbalance between cylinders can cause engine to not start. Low compression could mean a blown head gasket which may also explain loss of coolant and hot running.
Check for spark and fouled plugs.
Compression and spark testing tools are easy to use and are available at most auto parts stores.
Check fuel pressure although you believe fuel is not the problem and the sound you hear when you turn the key to on may be the fuel pump priming. That sound usually comes from the rear of the car. I personally have not checked fuel pressure but there are lots of videos available. Or search this and other Civic sites.
Here is a link to a similar problem. Unfortunately the issue was not resolved.
