yea. the goofy part is i have a diffrent style of relay, mine is under the hood and big instead of the little one that runs on the kick pannle, just irritating,

Did you check your fuel pressure?

Id check the pressure at the rail. Also, you had your car at the bricks right? Looked very nice, my dad was admiring the paint.

i'd check the relay and fuel pressure first.

can you hear the relay clicking on when you turn the key to prime the pump?

if the relay sounds weird, try reading the voltage on the signal to the relay from the pcm, battery and see if its clean.

i had a problem with my car this year, turned out to be the pcm, something died that kept the relay on when the key was turned, found this after replacing the pump and relay.

good luck
