I'm thinking about an instrument cluster that will tell me what's happening
to my 91 2.1L DoKa as I drive.  Here's the problem:

Starts right away.  A block later we die.  Sometimes starts again,
sometimes not.  Sometimes idles at stop signs, sometimes not.  If I park
for 5 minutes, maybe we start again, maybe not.

It's time I solve this problem.  So the problem might be electrical, or
maybe fuel-trical.   Fuel-trical?  Fuel-trackle?  Well, a fuel problem.

Is there a diagnostic cluster I can put on my dash so I can monitor my
engine?  Or lacking that, what is the first steps in driving diagnostics?

ed-91 DoKa, mostly parked in my driveway.
