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.

does your car have the signal light flasher if so find it and replace it also check the fuses maybe both sides are fused separate

Replace the switch you must have broken it

Use a fuel pressure gauge to test pressure at key on, and while running. Compare to spec's for your engine.

Fuel problem by the sound of it the fuel keeps running back to the tank and you have to eind it heap untill the fuel returns to the carby fuel pump or maybe hole or leak 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

replace the serpentine belt and adjust it properly

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.  

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

Take all the spark plugs out and bring #1 piston up to TDC. Look at the timing mark on the pulley. If they don't line up, then timing has jumped. If that's the case replace the chain and both the cam and crank gears.

Number 1 is closest to the front of the engine. The front has all the pulleys and the serpentine belt.

Look for missing rubber parts around where that attach points are for the sway bar. Grab the sway bar and try to move it in any direction. If it moves then some rubber parts need replacing. There are rubber parts in the shock tower too. Age shrinks these parts, so look there too. Bearings don't make a clunking type noise, more of a grinding noise. To check a bearing. jack up one side till the tire turns freely. Grab the tire at the top and push and pull it towards you. Excessive play suggests a bearing is worn. Spin the tire. If it rolls slowly and stops abruptly , it's bearing time.

If you can, air dry the complete engine compartment where you used water to clean it. Possibly a few electrical connectors to the ignition system are wet. If you can disconnect these and air dry them, it may help. If you have not performed any type of maintenance like tune up, good time to do so.
