my fuel system on the electrical side of things was perfectly fine and worked flawlessly yesterday, but today, after uploading a stock map onto it. My fuel pumps didn't want to work.

both pumps are functional, all wiring was intact and great. But one really odd thing I have never really seen before (when I was probing around with a test light). My 5v fuel signal (that I am using to trigger my relays for my pumps), when i key the car on....instead of me getting a 5v for like 2 seconds and then it disappearing, it instead comes on for a millisecond and goes dead (i get nothing when im cranking the car either).

I thought it may have been a stock fuel pump relay problem, but it doesn't seem like it.

Have you guys ever seen something like this before?
