showing no fuel pressure

[CHINI]

Well got my car back from the shop today and i filled it up with a tank of 91. I drove a few miles and the car starting rumbling at the light. I didnt even get on it. It really scared me! I look at my gauges and i had 5 fuel pressure. So does that mean my frps went bad? If it is, i am sure thats an easy fix. I have never blown one.

That could be the problem. I always carry a spare with me, but I have not had to use it yet. Either that, or the fuel that you got was really shitty.
