I will check those issues and let you know how it turns out. I assume if I replace the cam or crank sensor I will need to have the timing reset?

No, the sensors are in fixed positions--nothing to adjust. The PCM first uses the crank sensor to initialize the firing of the COPs, firing both cylinders that are at TDC, one is a wasted spark. Once it (the PCM) picks up a stable cam sensor signal it fires only the charged cylinder. The output of both sensors are used to calculate injector timing.

One other thing, I have sometimes been told the "generator" thing is a Ford only issue. Not so, here are some other schematics:

2001 Camaro LS1:


2001 Dodge RAM:


2008 Cadillac DeVille:


2009 Suzuki Burgman:


You will find that as last as the early 90s some US manufacturers were still referring to the "alternator", however few if any still do. Some of the European makers still do...

I put a new generator in the car. Didn't fix the stalling issue. One the up side the old one wasn't charging the battery anyway so I didn't lose anyhting by replacing it. I can hear a whine coming from under the car and not from the engine compartment. It is like the sound that is made when you run a wet finger around the rim of a crystal goblet. Could this be the fuel pump? And why would it shut off when the car is at operating temp?
