What is your question?
Injector failure code . 1,3,5 lean 2,4,6 rich.
ECM had hole in bottom & pulled in moisture . BCM lost interior lights . Have quality scanner . Says invalid pass lock code . Starts ok but runs poorly . No change when # 1, 2, or 3 injectors are cancelled out . 4.3 w/manual trans.
Strongly suspect fuel spider 'assembly' .. Fuel pressure test required. .. That's about the only thing that would cause lean on one bank and rich on the other... Don't think engine would continue to run on invalid passlock code! .. Start and die maybe but not run continuously... Hint: when engine is switched off - fuel pressure should NOT drop off more than 5 - 10 psi. (Am assuming any ignition system problems have been eliminated(?)
Thanks . Will test fuel press. Was thinking it could be that the BMC needed to be flashed for this vehicle .
BCM has no control over engine! .. Passlock enables - disables all fuel injector pulse through ECM.... IF disabled, security light in dash would be flashing and engine would not run continuously. Good luck with it!
Thanks for you're reply . Figured it out . Invalid pass lock code put ECM in limp mode . Flashed BCM , relearned pass lock & reran crankshaft learn . Running fine for now .
