i see u have changed your fuel filter.
i do not know where u r at now because your last post was Friday. if u have not started on the injectors u might want to try the starter fluid a couple of times to see what happens. may be it u can get some new gas into the injectors it might clean it up. if i was working on it i would want to put a fuel pressure gauge and measure the pressure on it however u might have a prob with cost or availability.
it seems that u have a limited mechanical ability so u might consider a good bike shop. if u do pull the injectors i would take them to a professional to have them cleaned.
when the bike starts can u get it to rev a little? may be will rev if u try the starting fluid and then see if it will rev? hth
