Help! My '88 Justy Just Keeps On Dying!

Now, it's doing it all the time. In town, on the freeway, whatever. It runs perfect when it runs but you never know when it will shut down on you. Sometimes it'll start other times you have to leave it where it sets for a day or so and then it will start, (eventually).
I just changed plugs, plug wires, rotor, distributor cap and the coil. Didn't help. A guy told me the exact same thing was happening to his wife's Ford Explorer and it was the oxygen sensor. Does this sound legit?
I live very rural and there are no dealers and the few mechanics here don't know diddly squat about any car newer than about 1975! Help me please!!!

Also check for loose ground connections, and corroded connections - especially around where the battery is located. These can cause intermittant random behaviour as you describe.
I would think by your description that you have an electrical gremlin somewhere - since it runs fine when it's running.

Try changing the fuel filter(s).

I'd also recommend running some SeaFoam/MarvelMysteryOil or your favorite carb cleaner through it.

I know where the main fuel filter is under the body, in the rear of the driver's side. I changed that one but does anyone know if there IS ANOTHER one somewhere? I wish I could be so lucky as it being a fuel filter!

Next time it cuts off, check for spark. If no spark, the module in the distributor sounds likely.
If you have spark, check for fuel in the fuel line to the carb.
It could be that there is crud in the fuel tank also. I've heard of crud getting sucked up on the intake screen and plugging it so the motor dies, then, after sitting a bit, the crud falls off and allows it to start.
Good luck and let us know what you find.

I tried a few NAPA el-cheapo replacement pumps, and they would not hold up to salted roads and rust. I finally spent the extra money and bought an O.E.M style pump (still from NAPA) and it's held up much better.
For reasons I can't explain, I haven't had a fuel pump go in any of my injected vehicles, yet the pump doesn't look to be of any better quality than those used in the carbed vehicles. Who knows? I wish they had the pumps in inside tank.

Intermittant problems stink!!!!
I have had that sympton in several cars.
A VW fox and it turned out to be the fuel pump.
A Cavalier and it was the esc electronic spark modual.
A Olds 88 and it was the ecm.
A Camaro, fuel filter, though not identical symptom.

If there is no spark, try replacing the module or the whole dizzy.
If you have spark, then it's probably a fuel delivery problem.
Good luck and let us know what you find!

Your problem seems to be temperature related, Yet you did not mention much about temperatures when the problem occurs.
Ask yourself these questions:
1.When the car cuts out is it warmed up to operating temp?
2.Does it cut out after a certain amount of minutes of run time regardless of engine temp?
3.What is the outside temp like when it cuts out? Does outside temp increase = Cut out frequency to increase and Length of time I have to wait to restart the car to increase.
The answers to these questions will help to narrow down the problem.
My guess is you will find a bad ignition module. But, Check Fuel and Spark to be sure!!!. (side note: My car has the original fuel pump and it has 173,000 mi on the clock..Its on its 2nd module)
