my 94 intermittently shuts off while driving.i have a CEL code of either 3 flashes then 5 and 5 or 1 then 2 then 5 and 5.there's also a strong fuel smell in the cabin.i can hear the the fuel pump cycle and the pressure sits at around 30psi and jumps to 40 psi with vacuum off.after it shut down on my way home I noticed there wasn't any fuel pressure at rail valve when I pressed it.this all started yesterday while I was parked for 10min with the A/C on. after I drove off it shut down and only restarted when in neutral(changed NSS) 4 months ago.
