Short B+ and Fp terminals on the diagnostic port on left shock tower. This should energize the fuel pump bypassing relays, if pump runs, then fuel pump relay or fuse is bad.
If pump does not run, then pump is bad or wiring to it.
You can also remove the air tube to throttle body, spray some starting fluid in, if car starts and runs for a few seconds, then the pump/fuse/relay is bad.
If car does not fire, then ignition problem.
