The Passlock™ lock cylinder is a locking cylinder that turns a rotating magnet past a stationary hall effect sensor. The rotating magnet creates a resistance code (R-Code) that the cylinder sends to the instrument cluster.

I would have a close look at the fuel pump.These are one of the weaker links in the vehicle.Key On -Engine off will run this intank electric pump for 3 seconds.This gives you an opportunity to listen for the pump and how it sounds overall(in a quiet place ,like a closed garage)...Sometimes a failing pump sounds a bit squeelish and loud,somewhat labored.A good working ,fresh pump sounds very smooth and quiet.Fuel pressure diagnostics might be in order as these pumps seem to work about like they sound....good luck
