ok on todays automobiles the gas cap does more than just seal the gas tank. Now they run a return line to the tank. this does 2 things. it returns un used fuel and vapors back to the tank , and it pressurizes the tank to help improve the fuel pump. Now as it is possible running without the gas cap may cause problems I am not 100 % positive that is your only problem.It sound like the knock sensor is detecting the knock you mentioned and is trying to retard the timing to fix it . In doing so it has retarded it to far causing the engine to loose power and eventually stall. I would first replace the gas cap. then run a good gas additive to a full tank of gas to clean out any water and dirt that may have gotten into the tank while the cap was off. now the issue of the knock as you described. is it a knock or a ping? A knocking sound is loud metallic hammering noise. a ping is a ting not very loud. if it is a loud metallic sound I would have a reputable mechanic check it soon, as it could be a serious issue. Ping can be caused by bad or weak gas or cheap low octane gas. I would run a mid grade gas in it and see if it fixed the issue.

you might have air in the cooling system, or water pump might not be functioning right, I would try burping the system first too see. with the car off and cooled down pull the radiator cap off and start the car, let it run for about 30 minutes should force all air out of the system, keep a eye on the coolant level while doing this.

where is this f....fuse?

don't know if you can but you can try resetting everything. you disconnect your battery for 10 mins (positive post on battery) then reconnect it then start your car.

If you replace the timing belt, you line up the marks. There is no special timing. all you do is make sure cylinder one is Top Dead Center then install timing belt

Bad Battery Ground wire obviously willHave to keep in mind, only corrosion or a wire harness rubbing, would be an issueYou should have no issues there on a 2004vehicle,not that old to have those problems

it wont start just crank and crank

vibrate yes

check the fuse block out under the hood. the best way to check then is with a continuity tester. if it beeps its good. some times they are good but they are not seated good in the socket. Issues like this I always pull each fuse and test it then reseat it to make sure.

check fuses then check connection to the outlet

headlight fuses are out under the hood. check to see if they are good. some have a relay they will go bad. they should be marked to indicate what they are

ok first check cable to transmission to make sure it is properly adjusted, Does it lock into park ? (ie does the parking cog engage and hold the car from moving) If the park cog does engage the I suggest rebuilding the transmission as the band inside the transmission may be worn and welded to the drum.
