1994 miata stalled and now won't start

Hi,

I have a 1994 miata. Back in March I started to have a few problems.
I noticed that the tachometer stopped working and then on the way home
one night the car just died and rolled to a stop. Since I have
~120,000 miles (~60,000 since the last timing belt change), I figured
that the two problems were unrelated and that the timing belt broke.
After the car died, the electrical system seemed to be working (stereo,
lights, starter) but the car just wouldn't start.

Well, today (8/5/2006) I found time to start working on my miata. The
timing belt is intact, but before I replace it (and the water pump, cam
seals, thermostat etc.), I thought I should ask the group if anyone has
had a similar problem. Could the stall be an electrical problem (fuse,
computer) or perhaps the timing belt slipped? I have "Rod's 1.8 Liter
Miata 'Shop manual'" and I have found the nice web-pages that show how
to replace the timing belt etc.

I haven't worked on cars for > 20 years and I could use some advice.
I'd hate to get stuck in a loop trying to figure out if the timing belt
was installed incorrectly or whether the initial stall is due to
something else.

Thanks!
