[Shotimes] SHO will not start

[Wax, Ed]

I have a '91 SHO.  It will crank but will not start.  I am not
mechanically inclined so I had it towed to a Ford dealership here in the
Denver area.  It's been 2 weeks now and they still cannot get it to
start, even after consulting with the big boys at Ford Engineering.  Has
anybody out there had this problem before and found a way to fix it?
I've looked through the archives and have seen a number of WON'T START
posts.  I've been told I need a new PCM (pretty sure that's the name)
but a new one didn't solve the problem.  Any help would be appreciated.

Thanks,
