Default Car Won't Start

A little background information on the car: It is a H/C/I car with most bolt-ons.

About three weeks ago, I washed my engine bay before a car show. After the show my car took about three attempts of starting to get it to fire. From then on it took more and more attempts to get it to fire. The starter will turn the motor over, but it will not fire.

To remedy the problem I have installed new spark plugs, plug wires, cam sensor and crank sensor. I have also checked every connection and fuse. Nothing seems to be out of the norm. I scanned the car, but it is not throwing any codes.

Any input would be greatly appreciated.

I have not checked for fuel pressure, but I do have fuel in the rails.

I do not know how to check the coil packs for power.

Get a piece of wire and strip 2'' of the insulation off one side, and get a alligator on the other side. Take the striped side and rap it around any spark plug you may have laying around. Pull one of your plug wires off and plug it in to the random plug. Ground the alligator clip to the engine and have some one crank the engine while you watch the plug for spark.

It is raining here, so I have not been able to get a video yet. Will I have to re-tune my car if I reset my PCM?

Take the positive and negative ends that connect to the battery, disconnect them, and touch them together for a minute.
