<Has anything been done on the vehicle recently that may have caused this issue?>
No, only the information I provided in the background section.
<Is the scan tool powering up but not communicating with any computer in your vehicle?>
Yes, that is correct. I tried two different scan tools, an Actron and an AutoTap. I've used the Actron successfully with this truck before. The Actron powers up but does not communicate. The AutoTap is a PC-based tool, so "powering up" is not an issue (it is self-powered). I then plugged both of these into my other truck (2000 Suburban) and both recognized it, so the problem does not appear to be with the tools.
Again, the problem is:
--Vehicle cranks but does not start.
--Scan tool does not recognize vehicle.
Hi. I believe I said, both in my original post and in my first response to questions, that the fuses had been checked. I checked all fuses in the big fusebox under the hood with a multimeter and verified continuity.
