Code 2215 low fuel pressure

[Brock]

I took a air gun and blew out the transfer pump real good then reinstalled it and I swear when I turned the key on, I saw that pressure guage slowly go up over 10 psi but then when I grabbed the guage to get a picture, it was at 0 or just above, maybe 5. Ffs!!

I'm gonna check and see how the regulators work and if theres a bypass valve in the ifsn or something that could be making it have fuel and be running but yet have no fuel pressure?

I'm also going to swap that compucheck fitting to be safe, I used the same one when priming the system to drain fuel into a bucket so I'm certain it's not plugged but may as well rule it out.

Anyone have any ideas? No fuel pressure says bad fuel pump but as someone stated earlier, my engine should be running if its showing no fuel pressure.....
