Woa.... beaucoup info here... Thanks, I will keep you posted..

 

Thanks you two,
Chump, I think the wiring diagram you included is for a 5.9 engine.. I have a 318 (5.2L) engine.. For instance, I do not see the fuel pump relay on the diagram.....
Question: I should be able to check the "J2" voltage on pin 5 of the diagnostic connector, that seems to be the closest place to the PCM????

 

Final chapter: Is was the computer....

Thank you all
