if you noticed no spark you must have maybe put the plug wires on wrong this happens you need to get the firing order and trace that down, make sure all wires are put in correct order, Is it turning over, you didn't say mayber more details would be good.

There is a possibility this could be your fuel pump fuse. Without current the fuel pump will not pump fuel and the engine will not run. Can you be more specific about which fuse is being blown? The fuses in the engine compartment are identified in the diagram on the fuse box cover. If this is not legible, take a picture and post it here to identify the fuse. The fuses in the inside compartment are identified in a diagram on the fuse panel door.

Does the fuse blow as soon as you turn the key in the ignition, or does it blow after you crank the starter?

Try this: turn the ignition key to the on position. The fuel pump is right under the rear seat on the passenger side. If it is running you will hear it humming. You can also hear it humming from outside the car. It will run even with the engine off, but with the key in the on position. If you do not hear anything, the fuel pump is not running.

If the fuel pump is not running it could be due to a number of causes. Could be a faulty pump, or faulty wiring, or faulty harness. You will need to diagnose the cause with a voltmeter.

Under hood, driver side, rear engine area, passenger side of master cylinder, mounted in fuel line ,

try a simple fix of putting injector cleaner in the tank to clean the injectors check for any loose body screws and panels

Check all the wiring from the vehicle speed sensor (VSS) to the ECM, including all connectors. It seems that there may be an intermittent open (or short) causing the ECM to sense the vehicle slowing down/stopping.

you take the vehicle to an accredited auto electrician and have them check the charge circuit and battery could be the alternator or voltage regulator or problem battery have them check the drive belt condition and tension if the units have been rebuilt by reputable electrical company, they are a cheaper alternative to brand new and should have a 6 months or 12 month warranty with them

You need an aftermarket serviice manual from Haynes or Chilton. They will have that kind of info.
I know of no car (I don't know them all) where that is needed and depending on the cover material (sheet steel or cast), could lead to warping and new leaks. I always use a thin film of silicone whether it is specified or not and there are torque specs for ALL valve covers I have ever seen.  

try checkin your dashboard wiring or checkin yor fuses.

Cannot confirm. Need to verify other sensors are functioning properly--map sensor, tps, maf...is the engine light on?
