Here are the relevant details ...
Thursday evening, when I started the Vette to move it back into the garage, I noticed that it turned over just a bit reluctantly. Not enough to keep it from starting, but just on the edge of my consciousness.
Yesterday morning, getting ready to pull it out of the garage, it did the same thing (this time I was paying attention to it). I pulled it out, shut it down, then restarted it, and the starter motor sounded like it normally does.
Yesterday afternoon, the wife and I decided to take a Friday afternoon drive. It was back to the "slow" start - but started. When we stopped to get a drink, I stayed in the car with it running. At that time, I noticed that SYS was flashing.
We then returned home (no sense tempting fate). I then consulted my trusty FSM, which states to pull the codes.
I also took a look at the Delco battery (I'm pretty sure it isn't the original), and it has a nice green dot showing.
At that point, I decided to fire it up again. Battery voltage prior to starting (after the fuel pump primed & stopped) was 13.7 V. During starting, it dropped to about 10 (hard to tell). The car fired up with no starter hesitation, and battery read 13.7 V. I turned on the AC, and battery voltage crept up to about 14.
However, this time there was no SYS light flashing.
I pulled the following codes this morning ...
H31, H33, H35, & H37 - all from Module 1
There are no current codes.
How long before these codes go away? 100 starts?
I also took the car to Autozone, where they tested the battery. That test came back indeterminant. At the end of the test, the machine said to recharge the battery and repeat the test. That would seem to point toward a battery that is getting ready to fail.
Any thoughts/suggestions?
Thanks,
Steven
