How old is your battery?
I had replaced my CPS with an Advanced Auto one.. a few months later I noticed it seem to take and extra second or so of cranking to start. I
was ready to put my spare Bosch brand in come the upcoming holiday weekend.

This went on for about a week or so.. then I had a battery without enough juice to engage my "autostart".. just one click and that was all.

Gotta figure your reading voltage from the alternator aren't you? Or are you turning on the key and waiting for the blue tooth connect and checking voltage...
