fuel pressure at the schrader valve? hook a gauge so you can see what is happening with key on, cranking ,etc.
if not mentioned, the FP relay is likely under the driver side seat. if not, on some later cars, it can be found on the pass side fender. you can also jump the terminal on the self tester to run the fuel pump.
also, while im not a fan of starting fluid, as NKau mentioned, giving a shot might not be bad and really helps with quick diagnostics.
good luck.
