[QUOTE="Fouledplugs, post: 425284, member: 18666"] Are you using an actual fuel pressure guage at the rail? Battery voltage good? Have you pulled the relay and physically inspected it for issues like burned melted, or corroded terminals? Have you tried swapping in a new relay? Even though a relay clicks, doesnt mean it is still fully operational. Hell, you could even jump it with a jumper wire and it should activate the pump, eliminating the relay. Having said that, the pump is your next part to troubleshoot. If power is getting to the connector at the fuel pump, diagnosing the pump woul Can you hear the pump prime when you place the ignition in, “key on, engine off.” [/QUOTE]
