My shop had my Justy for 5 weeks and could not locate the component that
was 'droppping out'. They replaced the distributor, coil and attached
module, and a few other components. I am now even supicious of fuses.
. . .The 'check engine' light is usually on, unless it is a very cold
morning. The problem has been isolated to ignition. The code readings are
'fuel mixture solenoid'. I purchased another used one (top half of the
carb) 3 years ago, and it made no difference. I had a foreign vehicle
specialist work on it and he discovered both 'fuel mixture solenoids' were
functioning properly and the 'empty bowl' sensors were also
okay.
Initially, the car starts with no problems. But after running about 12
minutes, it quits. If I park it before it quits, the 'latent' engine heat
is enough to keep it from starting for about 15 minutes. If I try to start
it after it has been parked, after a run, it takes about 15-20 minutes. It
also seems the more I try to start it, unsuccessfully, it prolongs the
'wait' time before it starts. Usually when I get towed home, it starts
about one block from my house.
. . ..There is a transformer located in the engine compartment, on the right
fender well, that I believe may be a power supply/stablizer for the
computer...Car is 4 speed, and not injected. When it runs, it is a dream...
when it stalls, it is a study in patience.. . .
. . . I'm hoping to get info on any relays, ballist resistors, condensors,
or other electronic components I can check out by cooling with refrigerant.
thanks.



A reply to your OTHER POST had some good advice. Have you fed some gas
directly into the carb throat? If not, do it to isolate fuel vs. electrical
problem.

If it appears to be electrical, temporarily put lamps, or suitably
current-limited LEDs, on the electrical points of interest so you can see
where you do and don't have voltage when the failure occurs. If you can get
wires through the firewall, I suggest you put the "lamp box" in the car
where you can immediately see them while coasting to a parking place.

Frustrating, isn't it?

Good luck.
