This is not a question but some information that I want to share. I had trouble for about two years with the fuel pump not starting, sometimes, for days at a time. I spent a lot of money having diagnostics and work done, but no-one could find the problem.
I discovered that a chip called PCM and the relay for the fuel pump, in the black plastic box located under the hood, needed to be changed. Total time was about 2 minutes and the total cost was $52.00. Problem solved.
