CHEVROLET IMPALA FUEL PRESSURE PROBLEM

2001 Chevrolet Impala

Having a intermittent no crank problem. When no crank condition happens with key in crank position the bendix wire has no volts.
Maybe neutral safety switch or Ignition switch?

I noticed that when the car is running I can turn the key in the crank position and starter will not come on. Good for the flywheel but I think that feature could be hanging up intermittantly.

I need to find out how that works. Thanks

Closed O2 sensor reading fluctuates between.050v and.800v approximately, is that normal, or a little lean?

What is the fuel pressure suppose to be?

Fuel pressure is 52 psi at idle, and 58 psi at a quick full throttle.

Can you get me a better diagram of the starting system. I think is one of those integrated PCM systems. Thanks
