Replaced wires, plugs distributor, timing chain, fuel pump, just about everything I can think of even tried starting fluid but it just won't run. Tries to start but won't run.
Have you checked for a broken timing chain, that would be the next step. Make sure number one cylinder is up on compression stroke when the timing mark is on 0 degrees BTDC on the crank pulley. Pull the plug and feel the pressure as it nears TDC.

Hello I would think if you replaced all those components, It would lead me to say its the ignition module, Or Pickup coil, they are both located under the distributor Cap. Fairly Easy to change should take about 15 to 30 minutes depending on you mechanical ability. I sure hope that Helps you out. If not get back and we can do somemore trouble shooting, For spark,fuel pressure. Ect.. Thanks Hopefully that will get you going.

Just from what you said it sounds like your vehicle might not be holding its residual pressure which means after you turn a vehicle off, your fuel injection system should hold a certain amount of pressure in the system, but if that pressure drops to fast your vehicle may have a hard time starting. Things to look for when you lose fuel pressure is the fuel pressure regulator may be leaking, fuel pump check valve,leaky fuel injector or they maybe a small leak in one of the fuel lines. I only suggested this cause i had a car with the similar problem.

looked it up online, looks like its in the underhood fuse box but couldn't get a good diagram that shows which relay number it is. the website i use is sort of dependent on the manufacturer, apparently acura did not feel like sharing that info. hope that helps
