2FBE and JB4 G5 (HELP!)

I installed the JB4 G5 ISO in my car the other day, drove around, and then got the 2FBE code once i stopped the car. There were also 3 continuous beeps that repeated from the engine bay once the code was thrown. This continued all night and drained my batter to the point where it wouldn't start. Has anyone experienced anything like this? I installed everything exactly as the instructions say. Any and all help is greatly appreciated!

I would double check installation since it only happened after you installed the JB4.
As for the code it indicates that your HPFP is giving out.

I uninstalled the JB4 and everything turned back to normal most likely indicating faulty JB4 G5 board, I sent it to Terry to have diagnostics done and he's going to let me know if it is the board or not. Thanks for your help!

Update please.

I realize this hasn't been updated in a while but my roomate has identical symptoms.

Did you ever resolve this? Was it the board? I unistalled and re-installed the JB4 twice to confirm it only makes the noise and throws 2FBE code with it installed.

Always possible I messed up the install twice but I have had the JB2, JB3, and JB4 installed a dozen times on my own 335 without a hitch, so I feel pretty confident with it at this point.
