When I did the timing belt on my 94 Mazda B2300 I did exactly that. Started it and let it run 60 seconds or so with none of the components you mentioned hooked up. I too wanted to be sure it would start and run without reassembling the whole thing. The timing cover just snaps into place. As far as an illustration get a manual for your truck. They arent expensive and it will come in handy with other problems/repairs. Or you could probably google it and come up with pics and instruction. Its not a hard job to do the actual belt change will take less than 20 minutes its the disassembly and reassembly that is time consuming.That crank bolt is tourqed over 100 lbs. An impact wrench will most likely spin it out. Replace the timing belt tensioner while your there too. If it does start and run you might want to replace the water pump and thermostat while your that far into it. If this truck hasent ran in a few years the fuel will be separated and varnish like. So get as much of the old fuel out and replace it with fresh gas. If and when it starts you will want to run some sea foam through the fuel to clean up lines ....injectors ect
. As far as hoses look at the junk yard or go on Ebay. Good luck with your new truck I BET you will get it figured out.
