It sounds like ther might be an intermittent ignition (spark) problem... when the plugs don't fire, they will get wet with fuel...
So check all of the ignition components, make sure there are no loose connections to the coils are plug wires.
It is also possible that there might be a problem in the fuel injection, such as an injector stuck open and continuously feeding fuel to its cylinder (which would show as only ONE plug being wet), or possibly a bad fuel pressure regulator, letting fuel pressure in the injector rail go too high and causing an over-rich mixture and engine flooding (symptomatic of ALL plugs being wet).
Once the engine is "flooded" it is sometimes hard to "clear" the engine with modern injection systems, but try this: Hold the accelerator to steadily to the floor while cranking --- DO NOT PUMP THE PEDAL! --- This will allow the maximum amount of air to mix with the overage of fuel in the cylinders and help the engine to eliminate the excess without also adding too much back in...
If you still can't get it to fire off doing the above, then remove the fuel pump relay or fuse and repeat the above until the engine tries to run.... It will run briefly until it fuel starves and dies. Then replace whichever you removed and try starting again with fuel delivery back in service.
Velma, I would have answered this sooner, but I've been on a "road trip" and only recently got back home. If you still have problems, please post a comment describing as best you can the situation --- you have to be my eye, ears, nose, and hands in this long distance effort! Also let me know why the head gasket blew, if known... Racing or overheating? If this does help, please remember to rate my assistance --- your approval is my ONLY compensation for providing this help!

A COMMON PROBLEM I'VE SEEN MANY TIMES IS THE CRANK SENSOR DISRUPTING COMMUNICATION WITH PCM. UNPLUG THE CRANK SENSOR AND CHECK FOR RESPONSE OF PCM. IF COMMUNICATION IS NOW POSSIBLE YOU HAVE A BAD CRANK SENSOR. IT'S A PROBLEM I'VE SEEN NUMEROUS TIMES. DOUBLE CHECK YOUR TIMING.

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.
