I'm having a really tough time figuring out exactly what could be going on here and I would like to diagnose the problem before I throw money at it. I currently have an 04 whippled cobra running 13 psi. I'm running a stock pump with a KB-BAP. For some time now the engine has been throwing two codes saying that both banks are running lean. I would imagine that if the fuel pump died the car wouldn't run (duh), and if the BAP is dead since it's wired to the fuel pump power source, wouldn't that cause the car to shut off as well? I haven't checked the 02 sensors yet, but not sure if they would throw out this code. Any ideas?
Possible reasons for throwing a lean code???

- Start date
That's what I figured, but I have no way of testing that theory. I dumped a ton of smoke into the intake and didn't see it leaking out anywhere. guess the next step is getting some propane.
