not sure if the 93 has the same check valves as my 97 but...

I just had a similar set of symptoms that started after installing my new fuel pump ... no starts... rough idle on occation vapour lock in the line that required jumping the pump fuse loosening off the fuel rail bolt until gas was spurting everywhere

The old valve looked fine but as soon as I put in the new valve my no start problem disappeared I hope its gone anyways ... its been only a day since install

My uneducated diy Guess is that the increased pressure from the new pump caused the check valve to fail

hope this is your issue as well I feel your pain
